Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-68686 is an information disclosure vulnerability affecting multiple versions of Fortinet FortiOS, categorized as an Exposure of Sensitive Information to an Unauthorized Actor (CWE-200). This flaw allows a remote, unauthenticated attacker to bypass a previously implemented patch designed to address a symbolic link persistency mechanism. The bypass is achieved through specially crafted HTTP requests, which can lead to the exposure of sensitive data. It is important to note that CVE-2025-68686 acts as a secondary exploitation vector. For this vulnerability to be leveraged, the FortiOS product must have already been compromised at the filesystem level through a separate, prior vulnerability. This means the vulnerability extends the impact of previous compromises by allowing attackers to maintain unauthorized access to sensitive information on already affected FortiOS devices.

Description: An Exposure of Sensitive Information to an Unauthorized Actor vulnerability [CWE-200] vulnerability in Fortinet FortiOS 7.6.0 through 7.6.1, FortiOS 7.4.0 through 7.4.6, FortiOS 7.2 all versions, FortiOS 7.0 all versions, FortiOS 6.4 all versions may allow a remote unauthenticated attacker to bypass the patch developed for the symbolic link persistency mechanism observed in some post-exploit cases, via crafted HTTP requests. An attacker would need first to have compromised the product via another vulnerability, at filesystem level.
