Description

CVE-2024-52962 is an Improper Output Neutralization for Logs vulnerability (CWE-117) affecting FortiAnalyzer and FortiManager. Specifically, versions 7.6.1 and below, 7.4.5 and below, 7.2.8 and below, and 7.0.13 (FortiAnalyzer) or 7.0.12 (FortiManager) and below are vulnerable. This flaw allows an unauthenticated remote attacker to pollute the logs via crafted login requests. Although the CVSS score is 5 (Medium Severity), the SOCRadar Vulnerability Risk Score (SVRS) is 30, suggesting a lower immediate risk compared to vulnerabilities with SVRS scores above 80. This vulnerability is actively exploited by hackers.

Key Insights

1. Log Pollution: The primary impact of this vulnerability is log pollution. An attacker can inject arbitrary data into the logs, which can hinder incident response, forensic analysis, and compliance efforts. Over time, this can obscure genuine security events and make it more difficult to detect malicious activity.

2. Unauthenticated Remote Access: The vulnerability can be exploited by an unauthenticated remote attacker, widening the attack surface and making it easier for malicious actors to target vulnerable systems. This ease of exploitation increases the likelihood of the vulnerability being leveraged.

3. Affected Products and Versions: The vulnerability affects multiple versions of both FortiAnalyzer and FortiManager, increasing the potential number of affected organizations. Specifically, it impacts versions 7.6.1 and below, 7.4.5 and below, 7.2.8 and below, and 7.0.13 or 7.0.12 and below depending on whether the product is FortiAnalyzer or FortiManager, respectively.

4. In The Wild: The vulnerability is actively exploited by hackers.

Mitigation Strategies

1. Apply Patches/Upgrades: Immediately upgrade FortiAnalyzer and FortiManager to patched versions. This is the most effective way to remediate the vulnerability. Prioritize systems exposed to the internet.

2. Log Monitoring and Alerting: Implement or enhance log monitoring and alerting capabilities. This will help in detecting anomalous activities caused by potential exploitation attempts. Focus on monitoring for unusual login request patterns and unexpected log entries.

3. Web Application Firewall (WAF) Rules: Consider deploying custom WAF rules to filter out potentially malicious login requests targeting the vulnerable components. This can provide an additional layer of defense while waiting for patches or implementing other mitigations.
