New FortiOS and FortiProxy Critical Vulnerabilities

Fortinet has released patches to address 15 security flaws, including one critical vulnerability in FortiOS and FortiProxy that could allow an attacker to take control of affected systems. The buffer underwrite flaw (CVE-2023-25610) is rated 9.3 out of 10 for severity and was discovered by Fortinet’s internal security teams. The vulnerability could enable a remote, unauthenticated attacker to execute arbitrary code on the device or cause a denial-of-service attack. Fortinet has not yet seen any malicious exploitation attempts against the flaw, but users are urged to apply the patches quickly, as prior flaws in software have been actively abused in the wild. Workarounds include disabling the HTTP/HTTPS administrative interface or limiting IP addresses that can reach it. Just last week, nGuard wrote about another Fortinet critical vulnerability that was actively being exploited. As this continues to develop, nGuard has a number of solutions that can help your organization stay ahead of the curve, including internal penetration testing and vulnerability management.

Over 40% of Industrial Control Systems (ICS) Were Attacked in 2022

Over 40% of industrial control systems (ICS) computers globally experienced malicious attacks in 2022, according to Kaspersky research into telemetry statistics. The report highlighted growth in Russia, which saw a 9% increase in malicious activity in 2022, but Ethiopia was the top target overall with 59% of its ICS footprint seeing malicious activity.

Kaspersky noted that blocked malicious scripts and phishing pages targeting ICS were particularly common threats, seeing an 11% rise from 2021. The percentage of ICS computers experiencing malicious activity varied from 40.1% in Africa and Central Asia to 14.2% and 14.3% respectively in Western and Northern Europe. nGuard has been helping protect Industrial control systems, SCADA networks, and critical infrastructure for over 20 years with security assessments, penetration testing, incident response, and managed SIEM services.

Low-coverage Cyber Insurance Plans Help Meet Compliance and Contractual Requirements

As the cyber insurance market experiences a surge in claims for ransomware attacks, insurance carriers and brokers have started imposing tighter rules on the companies that can qualify for coverage, raising prices and reducing the amount of coverage offered per policy. nGuard recently wrote about requirements needed to obtain cyber insurance. Policy coverages have significantly dropped in recent times, with some as low as $5m, and some companies cannot purchase as much insurance as they would like. However, some contracts and compliance regulations require that a company have a cyber insurance policy, which can pose a problem for those that lose coverage. Basic policies are now available for more organizations to obtain affordable coverage, allowing them to avoid a breach of compliance and fulfill contractual obligations.

Attacking FortiNAC Devices: Experts Advise Updating

A serious vulnerability in Fortinet’s FortiNAC network access control suite (CVE-2022-39952) is now being exploited by hackers to add a cron job that starts a reverse shell on vulnerable systems as the root user. This unauthenticated file path modification vulnerability poses a major security risk for enterprises using the FortiNAC solution because it may be used to execute commands remotely.

Fortinet has already released security upgrades to remedy the issue, and has recommended that users update susceptible appliances to the most recent versions. As the corporation hasn’t offered any mitigation advice or workarounds, updating is the only option to prevent attacks. Researchers from cybersecurity firms, including Shadowserver Foundation, GreyNoise, and CronUp, have recently observed attacks on CVE-2022-39952 from a variety of IP addresses. This indicates that attackers have already started focusing on unpatched FortiNAC devices.

Horizon3 security researchers have created proof-of-concept (PoC) exploit code which allows hackers to add a cron task that starts a reverse shell on vulnerable systems. Fortinet had previously issued a warning in December 2022 to customers to patch FortiOS SSL-VPN appliances against an actively exploited security flaw (CVE-2022-42475), which was also used as a zero-day in attacks against targets associated with the government.

In reaction to what it called “sensationalized claims” about recent exploitation attempts aimed at a vulnerability in its FortiNAC network access control product, Fortinet has offered some crucial clarifications. The company emphasized that it is yet unclear how exploiting CVE-2022-39952 will actually affect users. However, FortiNAC users should be aware of the possible hazard, as knowledgeable threat actors have been known to attack Fortinet products.

FortiNAC administrators are highly advised to update their software right away to a version of the software that is not impacted by the CVE-2022-39952 vulnerability. This includes FortiNAC versions 9.4.1 or later, 9.2.6 or later, 9.1.8 or newer, and 7.2.0 or later. Organizations may stop hackers from using this important vulnerability to gain access to their corporate networks by heeding this advice.

Are You Prepared for the New Cyber Insurance Requirements?

As cyberattacks increase worldwide, insurance companies are tightening their cyber insurance policy requirements. This is due to the 80% rise in ransomware attacks last year, leading to a large number of claims. Among the new provisions are the requirement for multi-factor authentication (MFA) for all admin access and the protection of all privileged accounts. However, identifying gaps in MFA and privileged account protection within a network can be challenging for organizations. In addition to MFA, there are several other requirements that stipulate detailed attestation when filling out a cyber policy questionnaire. A few of those requirements are:

Security Awareness Training and Testing
This process is designed to educate employees on cyber security threats and risks, and to test their understanding of these issues through interactive simulations and assessments. The goal is to raise awareness, increase knowledge, and promote safe online behavior within an organization. To reduce your risk of phishing attacks, nGuard has been conducting Security Awareness Training and phishing testing though our Social Engineering Assessment for years.
Vulnerability Management
A thorough vulnerability management program will identify, assess, and prioritize vulnerabilities in an organization’s systems and networks, and take action to remediate or mitigate these risks to prevent exploitation. This helps maintain the security and integrity of systems and data by staying on top of vulnerabilities as they are discovered. Conducting monthly or quarterly vulnerability scans on an ongoing basis will not only help meet insurance requirements but also keep your network secure. nGuard’s Vulnerability Management can help you manage your external environment, internal environment, and meet PCI requirements with ASV scanning.
24/7/365 Monitoring
A Security Information and Event Management (SIEM) system collects and aggregates log data from various sources within an organization and uses analytics and threat detection techniques to identify potential security incidents and enable security teams to respond promptly. SIEM provides centralized security visibility and event correlation. nGuard’s managed security team performs both manual and automated daily log analysis that proactively detects suspicious activity in your environment with our managed SIEM service called Managed Event Collection & Correlation. nGuard is adding artificial intelligence and machine learning to detect and respond to security threats in real-time via UEBA (User and Entity Behavior Analytics).
Secured, Encrypted, Offsite Backups
Offsite backups refer to the storage of backup data at a remote location, typically in a secure data center, separate from the primary data storage. This helps ensure that the data can be recovered in case of a disaster or cyberattack and protected against data loss while minimizing downtime. Offsite backups are an important component of a comprehensive disaster recovery plan. A Strategic Security Assessment utilizing the Center for Internet Security (CIS) 18 Critical Security Controls as the foundation can help bring the lack of controls like this and others to light.
Endpoint Detection & Response (EDR)
This real-time security solution will monitor and respond to security threats on endpoint devices such as computers and servers using artificial intelligence and machine learning to detect and isolate security incidents.

As insurance carriers adjust the requirements to obtain and maintain coverage, a thorough assessment can help organizations identify and close security gaps to help meet the new cyber insurance requirements and improve their overall security posture. nGuard has a number of solutions that can help meet and exceed the requirements needed to obtain and maintain cyber insurance.
