Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-61624 is a path traversal vulnerability (CWE-22) affecting the command line interpreter (CLI) of several Fortinet products, including FortiOS, FortiPAM, FortiProxy, and FortiSwitchManager. The flaw stems from improper input validation, specifically involving unsanitized `system.auto-script` object names. This allows an authenticated attacker with administrative privileges and read-write permissions to escape restricted directories and write or delete arbitrary files on the underlying filesystem by executing crafted CLI commands. In real-world attacks, threat actors have exploited this vulnerability as a privilege-escalation vector to transition from restricted administrative access to root-level control over the underlying operating system. This exploit has been used in the wild to deploy PEERSTITCH, a stealthy, memory-resident ARM64 malware designed to evade traditional file-based detection. Fortinet addressed the vulnerability in April 2026, releasing patches for affected versions of FortiOS and other impacted products.

Description: An Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') [CWE-22] vulnerability in Fortinet FortiOS 7.6.0 through 7.6.4, FortiOS 7.4.0 through 7.4.9, FortiOS 7.2 all versions, FortiOS 7.0 all versions, FortiOS 6.4 all versions, FortiPAM 1.7.0, FortiPAM 1.6 all versions, FortiPAM 1.5 all versions, FortiPAM 1.4 all versions, FortiPAM 1.3 all versions, FortiPAM 1.2 all versions, FortiPAM 1.1 all versions, FortiPAM 1.0 all versions, FortiProxy 7.6.0 through 7.6.4, FortiProxy 7.4.0 through 7.4.11, FortiProxy 7.2 all versions, FortiProxy 7.0 all versions, FortiSwitchManager 7.2.0 through 7.2.7, FortiSwitchManager 7.0.0 through 7.0.6 may allow an authenticated attacker with admin profile and at least read-write permissions to write or delete arbitrary files via specific CLI commands.
