FreePBX Patches Critical SQLi, File-Upload, and AUTHTYPE Bypass Flaws Enabling RCE

Summary

FreePBX faces critical vulnerabilities including SQL injection, file upload flaws, and authentication bypass. Patches are available for these issues, and temporary mitigations are recommended. Users are advised to analyze their systems for potential compromises.

Key Takeaways

1. Multiple security vulnerabilities have been disclosed in the open-source private branch exchange (PBX) platform FreePBX, including a critical flaw that could result in an authentication bypass under certain configurations.
2. "These vulnerabilities are easily exploitable and enable authenticated/unauthenticated remote attackers to achieve remote code execution on vulnerable FreePBX instances," Horizon3.ai security researcher Noah King said in a report published last week.
3. As temporary mitigations, FreePBX has recommended that users set "Authorization Type" to "usermanager," set "Override Readonly Settings" to "No," apply the new configuration, and reboot the system to disconnect any rogue sessions.
