AI Analysis
Technical Summary
The FreePBX missedcall module improperly neutralizes special elements used in SQL commands, specifically in agi-bin/missedcallnotify.php where inbound Caller ID names from SIP From headers are inserted into the missedcalllog database without proper escaping or use of bound parameters. This SQL injection vulnerability affects versions from 16.0.0 until 16.0.11 and 17.0.0 until 17.0.4. An unauthenticated attacker can exploit this when a monitored extension goes unanswered, leading to database corruption and unauthorized modification of FreePBX administrator accounts. The issue is resolved in versions 16.0.11 and 17.0.4.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary SQL commands, corrupt the FreePBX database, and modify administrator accounts. This can lead to unauthorized remote access to the FreePBX system, posing a critical security risk.
Mitigation Recommendations
A fix is available in FreePBX missedcall module versions 16.0.11 and 17.0.4. Users should upgrade to these versions or later to remediate the vulnerability. Patch status is confirmed by the vendor advisory stating the issue is fixed in these versions.
