CVE-2025-67604: Denial of service in Fortinet FortiAnalyzer
A use of potentially dangerous function vulnerability in Fortinet FortiAnalyzer 7.6.0 through 7.6.4, FortiAnalyzer 7.4.0 through 7.4.8, FortiAnalyzer 7.2 all versions, FortiAnalyzer 7.0 all versions, FortiAnalyzer 6.4 all versions, FortiManager 7.6.0 through 7.6.4, FortiManager 7.4.0 through 7.4.8, FortiManager 7.2 all versions, FortiManager 7.0 all versions, FortiManager 6.4 all versions may allow an authenticated attacker to cause a system hang via multiple specially crafted HTTP requests causing crashes. This happens if internal locks are aligned, which is out of control of the attacker.
AI Analysis
Technical Summary
This vulnerability affects multiple versions of Fortinet FortiAnalyzer (6.4.0 through 7.6.4) and FortiManager with similar version ranges. An authenticated attacker can exploit a flaw involving potentially dangerous function usage and internal lock alignment to cause the system to hang, resulting in denial of service. The vulnerability requires low privileges and no user interaction but has a high attack complexity. The vendor has released an official fix to address this issue.
Potential Impact
Successful exploitation results in denial of service by causing the affected system to hang or crash. There is no impact on confidentiality or integrity according to the CVSS vector. The attack requires network access and low privileges but is mitigated by high attack complexity. No known exploits are reported in the wild at this time.
Mitigation Recommendations
An official fix is available from Fortinet and should be applied to affected FortiAnalyzer and FortiManager versions. Since the vulnerability requires authentication, ensure that access controls are properly enforced. Patch status is confirmed by the vendor advisory indicating an official fix is released.
