Black Arrow Cyber Advisory 17 July 2023 – Cisco SD-WAN vManage Vulnerable to Remote Unauthenticated Access

Black Arrow Cyber Advisory 17 July 2023 – Cisco SD-WAN vManage Vulnerable to Remote Unauthenticated Access

Executive Summary

A critical vulnerability has been identified and addressed in Cisco's network management software, SD-WAN vManage. The vulnerability allows a remote unauthenticated attacker to gain read or limited write permissions to the configuration of an affected Cisco SD-WAN vManage instance. This vulnerability only affects the REST API and does not affect the web-based management interface or the command line interface.

What’s the risk to me or my business?

A successful exploitation of the critical vulnerability allows a remote unauthenticated threat actor to read sensitive information from the compromised system, modify certain configurations, disrupt network operations. This will compromise the confidentiality, integrity, and availability of data in your organisation.

The following Cisco SD-WAN vManage versions are affected by the vulnerability:

  • v20.6.3.3 – fixed in v20.6.3.4

  • v20.6.4 – fixed in v20.6.4.2

  • v20.6.5 – fixed in v20.6.5.5

  • v20.7 – Migrate to fixed version v20.8 – Migrate to fixed version

  • v20.9 – fixed in v20.9.3.2

  • v20.10 – fixed in v20.10.1.2

  • v20.11 – fixed in v20.11.1.2

What can I do?

There are no workarounds for the critical vulnerability. As such, it is advised that patches are applied immediately. For versions v20.7 and v20.8, Cisco advises customers to migrate to a fixed release. Cisco has given advice on how to reduce the attack surface for this attack, this includes actions such as monitoring logs for the REST API and limiting instances to specified instances. If you are unsure check with your MSP or network team to ensure these are in place.

Top Cyber Stories of the Last Week

  • CFOs’ Overconfidence in Cyber Security Can Cost Millions

Kroll announced its report entitled ‘Cyber Risk and CFOs: Over-Confidence is Costly’ which found chief financial officers (CFOs) to be woefully in the dark regarding cyber security, despite confidence in their company’s ability to respond to an incident.

The report, conducted by StudioID of Industry Dive, exposed three key themes among the 180 senior finance executives surveyed worldwide:

  1. Ignorance is bliss. Eighty-seven percent of CFOs are either very or extremely confident in their organisation’s cyber attack response. This is at odds with the level of visibility CFOs have into cyber risk issues, given only four out of 10 surveyed have regular briefings with their cyber teams.

  2. Wide-ranging damages. 71% of the represented organisations suffered more than $5 million in financial losses stemming from cyber incidents in the previous 18 months, and 61% had suffered at least three significant cyber incidents in that time. Eighty-two percent of the executives in the survey said their companies suffered a loss of 5% or more in their valuations following their largest cyber security incident in the previous 18 months.

  3. Increasing investment in cyber security. Forty-five percent of respondents plan to increase the percentage of their overall IT budget dedicated to information security by at least 10%.

According to Kroll: “We often see that CFOs are not aware enough of the financial risk presented by cyber threats until they face an incident. At that point, it’s clear that they need to be involved not only in the recovery, including permitting access to emergency funds and procuring third-party suppliers, but also in the strategy and investment around cyber both pre- and post-incident.”

“Ultimately, cyber attacks represent a financial risk to the business, and incidents can have a significant impact on value. It is, therefore, critical that this is included in wider business risk considerations. A CFO and CISO should work side-by-side, helping the business navigate the operational and financial risk of cyber.”

  • Cyber Security Outflanks Inflation, Talent, Logistics in Business Worries

Nearly six in 10 IT leaders in a new study view cyber security as their top business concern, ranking it higher than inflation, retaining talent and supply chain/logistics management.

Less than half of respondents (43%) believe their critical data and assets are protected from cyber threats despite increased cyber security investments by their organisations, greater board visibility and increased collaboration between the security team and the C-suite, Rackspace said in its new survey of 1,420 IT professionals worldwide.

The multi-cloud technology services specialist said that a “large majority” of the survey respondents report being either unprepared or only “somewhat prepared” to respond to major threats, such as identifying and mitigating threats and areas of concern (62%), recovering from cyber attacks (61%) or preventing lapses and breaches (63%).

Cloud native security is where organisations are most likely to rely on an outside partner, such as a managed security service provider, for expertise.

Here are more of the survey’s findings:

  • The top three cyber security challenges their organisation is facing: migrating and operating apps (45%); shortage of workers with cyber security skills (39%); lack of visibility of vulnerabilities across all infrastructure (38%).

  • 70% of survey respondents report that their cyber security budgets have increased over the past three years.

  • The leading recipients of new investment are cloud native security (59%); data security (50%), consultative security services (44%); and application security (41%).

  • Investments align closely with the areas where organisations perceive their greatest concentration of threats, led by network security (58%), closely followed by web application attacks (53%) and cloud architecture attacks (50%).

  • 70% of respondents said there has been an increase in board visibility for cyber security over the past five years, while 69% cite better collaboration between the security team and members of the C-suite.

  • Only 13% of respondents said there were significant communications gaps between the security team and C-suite, while 69% of IT executives view their counterparts in the C-suite as advocates for their concerns.

The authors stated “We are seeing a major shift in how organisations are allocating resources to address cyber threats, even as budgets increase. The cloud brings with it a new array of security challenges that require new expertise, and often reliance on external partners who can help implement cloud native security tools, automate security, provide cloud native application protection, offer container security solutions and other capabilities”.

  • Attackers Can Compromise Most Cloud Data in Just 3 Steps

An analysis of cloud services finds that known vulnerabilities typically open the door for attackers, while insecure cloud architectures allow them to gain access to the crown jewels.

Companies and their cloud providers often leave vulnerabilities open in their system and services, gifting attackers with an easy path to gain access to critical data.

According to an Orca Security analysis of data collected from major cloud services, attackers only need on average three steps to gain access to sensitive data, the so-called "crown jewels," starting most often — in 78% of cases — with the exploitation of a known vulnerability.

While much of the security discussion has focused on the misconfigurations of cloud resources by companies, cloud providers have often been slow to plug vulnerabilities.

The key is to fix the root causes, which is the initial vector, and to increase the number of steps that they attacker needs to take. Proper security controls can make sure that even if there is an initial attack vector, you are still not able to reach the crown jewels.

The report analysed data from Orca's security research team using data from a "billions of cloud assets on AWS, Azure, and Google Cloud," which the company's customers regularly scan. The data included cloud workload and configuration data, environment data, and information on assets collected in the first half of 2022.

  • Cyber Insurance Premiums Soar 80% As Claims Surge

Cyber insurance premiums have soared in the past year as claims surged in response to a rise in damaging attacks by hackers.

The cost of taking out cyber cover had doubled on average every year for the past three years, said global insurance broker Marsh. Honan Group, another broker, pointed to an 80 per cent rise in premiums in the past 12 months, following a 20 per cent increase in the cost of cover in each of the previous two years.

Brokers are calling cyber “the new D&O”, referring to sharp rises in directors and officers insurance premiums since 2018. Brokers were hopeful premiums would ease, but have warned insurers would continue to demand companies prove they had strong security systems and policies in place before agreeing to sell them insurance.

There’ll be a number of insurance companies that won’t even look at a business that doesn’t have a bunch of security measures in place. They’ll just turn around and say, ‘we’re not going to insure you’. The chief reason for the price rises is the increase in the number and size of claims relating to ransomware, where criminals use malicious software to block access to an organisation’s computer system until a sum of money is paid. In addition, some insurers left the market, while remaining players attempted to recoup the cost of under-priced contracts written in previous years.

The rise in the premiums is mainly due to ransomware and cyber attacks across the board have risen sharply over the past few years.

  • One In 10 Employees Leaks Sensitive Company Data Every 6 Months

Departing employees are most likely to leak sensitive information to competitors, criminals or the media in exchange for cash.

Insider threats are an ongoing menace that enterprise security teams need to handle. It's a global problem but especially acute in the US, with 47 million Americans quitting their jobs in 2021. The threat of ex-employees taking sensitive information to competitors, selling it to criminals in exchange for cash, and leaking files to media is making data exfiltration a growing concern. 

About 1.4 million people who handle sensitive information in their organisation globally were tracked over the period from January to June 30 this year by cyber security firm Cyberhaven to find out when, how and who is involved in data exfiltration.

On average, 2.5% of employees exfiltrate sensitive information in a month, but over a six-month period, nearly one in 10, or 9.4% of employees, do so, Cyberhaven noted in its report. Data exfiltration incidents occur when data is transferred outside the organisation in unapproved ways.

Among employees that exfiltrated data, the top 1% most prolific “super stealers” were responsible for 7.7% of incidents, and the top 10% were responsible for 34.9% of incidents.

North America accounted for the highest number of incidents at 44%, followed by the Asia Pacific region at 27%. Europe, the Middle East, and Africa accounted for 24% of incidents while 5% of incidents were recorded in South America.

  • Business Application Compromise and the Evolving Art of Social Engineering

Social engineering is hardly a new concept, even in the world of cyber security. Phishing scams alone have been around for nearly 30 years, with attackers consistently finding new ways to entice victims into clicking a link, downloading a file, or providing sensitive information.

Business email compromise (BEC) attacks iterated on this concept by having the attacker gain access to a legitimate email account and impersonate its owner. Attackers reason that victims won't question an email that comes from a trusted source — and all too often, they're right.

But email isn't the only effective means cyber criminals use to engage in social engineering attacks. Modern businesses rely on a range of digital applications, from cloud services and VPNs to communications tools and financial services. What's more, these applications are interconnected, so an attacker who can compromise one can compromise others, too. Organisations can't afford to focus exclusively on phishing and BEC attacks — not when business application compromise (BAC) is on the rise.

  • SMBs Are Hardest-Hit By Ransomware

Coalition announced the mid-year update to its 2022 Cyber Claims Report detailing the evolution of cyber trends, revealing that small businesses have become bigger targets, overall incidents are down, and ransomware attacks are declining as demands go unpaid.

During the first half of 2022, the average cost of a claim for a small business owner increased to $139,000, which is 58% higher than levels during the first half of 2021.

“Across industries, we continue to see high-profile attacks targeting organisations with weak or exposed infrastructure — which has become exacerbated by today’s remote working culture and companies’ dependence on third-party vendors,” said Coalition’s Head of Claims.

“Small businesses are especially vulnerable because they often lack resources. For these businesses, avoiding downtime and disruption is essential, and they must understand that Active Insurance is accessible.”

The good news: both Coalition and the broader insurance industry observed a decrease in ransomware attack frequency and the amount of ransom demanded between the second half of 2021 and the first half of 2022. Ransomware demands decreased from $1.37M in H2 2021 to $896,000 in H1 2022.

“Organisations are increasingly aware of the threat ransomware poses. They have started to implement controls such as offline data backups that allow them to refuse to pay the ransom and restore operations through other means,” said Coalition’s Head of Incident Response. “As ransomware is on the decline, attackers are turning to reliable methods. Phishing, for example, has skyrocketed – and only continues to grow.”

  • 65% Say Legacy Backup Solutions Aren’t Up To Ransomware Challenges

HYCU researchers are reporting 65% of respondents lack full confidence in their legacy backup solutions (HYCU is a multi-cloud backup-as-a-service provider).

According to the report, 65% of surveyed enterprise organisations are increasing spending on detection, prevention and recovery, and respondents are beginning to understand that air-gapped or immutable backups are the only ways to ensure that the backups themselves don’t fall prey to encryption worms when ransomware hits.

Key findings include:

  • 52% of ransomware victims suffered data loss

  • 63% of victims suffered an operational disruption

  • Just 41% air gap their backups

  • Just 47% routinely test their backups

  • Only 35% of respondents believe their current backup and recovery tools are sufficient.

  • Four-Fifths of Firms Hit by Critical Cloud Security Incident

Some 80% of organisations suffered a “severe” cloud security incident over the past year, while a quarter worry they’ve suffered a cloud data breach and aren’t aware of it, according to new research from Snyk.

The developer security specialist polled 400 cloud engineering and security practitioners from organisations of various sizes and sectors, to compile its State of Cloud Security Report.

Among the incidents flagged by respondents over the past 12 months were breaches, leaks, intrusions, crypto-mining, compliance violations, failed audits and system downtime in the cloud.

Startups (89%) and public sector organisations (88%) were the most likely to have suffered such an incident over the period.

The bad news is that 58% of respondents predict they will suffer another severe incident in the cloud over the coming year. Over three-quarters (77%) of those questioned cited poor training and collaboration as a major challenge in this regard.

“Many cloud security failures result from a lack of effective cross-team collaboration and team training. When different teams use different tools or policy frameworks, reconciling work across those teams and ensuring consistent enforcement can be challenging,” the report argued.

  • Homeworkers Putting Home and Business Cyber Safety at Risk

BlackBerry published a European research report exposing the cyber security risk created by cost-conscious homeworkers who prioritise security behind price, usability and ease of set up in their purchase of domestic smart devices.

32% of European home workers who own a smart device surveyed said security was a top three factor when choosing a smart device, compared to 50% who prioritised price. 28% of businesses aren’t putting adequate security provisions in place to extend cyber protection as far as homes. This heightens the risk of cyber attacks for businesses and their employees, as hybrid and home working become the norm.

The survey of 4,000 home workers in the UK, France, Germany, and the Netherlands revealed that 28% of people say that their employer has not done or communicated anything about protecting their home network or smart devices, or they don’t know if they are protected.

Furthermore, 75% of Europeans say their employers have taken no steps to secure the home internet connection or provide software protection for home devices. This failure to extend network security to home devices increases risk of the vulnerabilities created by hybrid and home working being successfully exploited. These are particularly sobering findings for small and mid-sized businesses who face upwards of eleven cyber attacks per device, per day, according to the research.

Through even the most innocent of devices, bad actors can access home networks with connections to company devices – or company data on consumer devices – and seize the opportunity to steal data and intellectual property worth millions. It’s likely businesses will bear the brunt of cyber attacks caused by unsecured home devices, with knock-on effects to employees themselves.

  • Uber Hacked, Internal Systems Breached and Vulnerability Reports Stolen

Uber suffered a cyber attack Thursday afternoon with an allegedly 18-year-old hacker downloading HackerOne vulnerability reports and sharing screenshots of the company's internal systems, email dashboard, and Slack server.

The screenshots shared by the hacker and seen by BleepingComputer show what appears to be full access to many critical Uber IT systems, including the company's security software and Windows domain.

Other systems accessed by the hacker include the company's Amazon Web Services console, VMware vSphere/ESXi virtual machines, and the Google Workspace admin dashboard for managing the Uber email accounts.

The threat actor also breached the Uber Slack server, which he used to post messages to employees stating that the company was hacked. However, screenshots from Uber's slack indicate that these announcements were first met with memes and jokes as employees had not realised an actual cyber attack was taking place.

Uber has since confirmed the attack, tweeting that they are in touch with law enforcement and will post additional information as it becomes available. "We are currently responding to a cyber security incident. We are in touch with law enforcement and will post additional updates here as they become available," tweeted the Uber Communications account.

The New York Times, which first reported on the breach, said they spoke to the threat actor, who said they breached Uber after performing a social engineering attack on an employee and stealing their password. The threat actor then gained access to the company's internal systems using the stolen credentials.

  • IHG Hack: 'Vindictive' Couple Deleted Hotel Chain Data for Fun

Hackers have told the BBC they carried out a destructive cyber-attack against Holiday Inn owner Intercontinental Hotels Group (IHG) "for fun".

Describing themselves as a couple from Vietnam, they say they first tried a ransomware attack, then deleted large amounts of data when they were foiled. They accessed the FTSE 100 firm's databases thanks to an easily found and weak password, Qwerty1234. An expert says the case highlights the vindictive side of criminal hackers.

UK-based IHG operates 6,000 hotels around the world, including the Holiday Inn, Crowne Plaza and Regent brands. On Monday last week, customers reported widespread problems with booking and check-in. For 24 hours IHG responded to complaints on social media by saying that the company was "undergoing system maintenance".

Then on the Tuesday afternoon it told investors that it had been hacked.
