An Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') [CWE-22] vulnerability exists in Fortinet FortiOS, impacting versions 7.6.0 through 7.6.4, 7.4.0 through 7.4.9, and several others across FortiPAM, FortiProxy, and FortiSwitchManager. This vulnerability allows authenticated attackers with admin profiles and read-write permissions to write or delete arbitrary files using specific CLI commands.
The severity of this vulnerability is classified as medium, with a CVSS score of 6.5, indicating a notable risk that should not be overlooked. Organizations utilizing affected versions could face serious operational disruptions if exploited.
Given the nature of the vulnerability, organizations should prioritize patching immediately. Adequate measures must be taken to close the security gap and safeguard sensitive information from potential unauthorized access.
Currently, no public exploits or proof-of-concept (PoC) code has been confirmed for this vulnerability, but the nature of the issue allows for a local attack vector, which increases the urgency for remediation.
Vulnerability Details
The identified vulnerability in Fortinet FortiOS is characterized as a path traversal issue, classified under CWE-22. This vulnerability impacts several product versions, including FortiOS 7.6.0 to 7.6.4, FortiOS 7.4.0 to 7.4.9, and various versions of FortiPAM and FortiProxy. The CVSS score of 6.5 reinforces the need for immediate attention, as it indicates potential for significant integrity and availability impact.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of user input within the CLI commands, allowing for traversal outside of the intended directories. Attackers with high privileges can exploit this weakness through a local attack vector, which requires low complexity and no user interaction, leading to high integrity and availability impacts.
Risk & Impact Analysis
Risk to organizations includes unauthorized file manipulation, which could lead to data loss, system corruption, or further exploitation. The blast radius extends to all versions of Fortinet products specified, thus emphasizing the need for an immediate patching strategy. The medium severity level and current exploitability status highlight the importance of addressing this vulnerability in the next patch cycle.
