Fortinet FortiWeb Path Traversal Vulnerability
Fortinet FortiWeb contains a relative path traversal vulnerability that may allow an unauthenticated attacker to execute administrative commands on the system via crafted HTTP or HTTPS requests.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
Fortinet FortiWeb contains a relative path traversal vulnerability that may allow an unauthenticated attacker to execute administrative commands on the system. This is a critical flaw given its high EPSS score of 0.89016, indicating a very high likelihood of exploitation, and its presence in CISA's KEV catalog confirms it has been actively exploited.
This vulnerability has been actively exploited in the wild. Unauthenticated attackers can remotely execute administrative commands via crafted HTTP or HTTPS requests.
Apply all available security updates for Fortinet FortiWeb. Implement robust input validation and ensure proper path sanitization to prevent path traversal attacks.
Technical Analysis
CVE-2025-64446 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-64446 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
