CVE-2026-54708: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in FreePBX security-reporting
FreePBX versions prior to 16.0.72 and 17.0.7 contain a critical path traversal vulnerability in the backup module. Authenticated users with sufficient permissions can exploit improper path sanitization in the backup restore functionality to upload malicious PHP files to the web root, enabling arbitrary code execution. This vulnerability has been patched in versions 16.0.72 and 17.0.7.
AI Analysis
Technical Summary
CVE-2026-54708 is a path traversal vulnerability (CWE-22) in the FreePBX backup module's restore functionality. It allows authenticated attackers with appropriate access to bypass pathname restrictions and upload malicious PHP files to the web root directory. This leads to arbitrary code execution on the server. The flaw is due to improper sanitization of file paths during backup restoration. The issue is fixed in FreePBX versions 16.0.72 and 17.0.7.
Potential Impact
An attacker with valid credentials and sufficient permissions can execute arbitrary code on the FreePBX server by uploading malicious files via the backup restore feature. This compromises the server integrity and could lead to full system compromise.
Mitigation Recommendations
Upgrade FreePBX to version 16.0.72 or later, or 17.0.7 or later, where this vulnerability is patched. No other mitigations are indicated by the vendor advisory.
