AzuraCast versions through 0.23.x have a command injection vulnerability in the Liquidsoap configuration generation for live recording. The vulnerability arises because the streamer username is not properly quoted in process.run calls, allowing authenticated station users with Streamers and Profile permissions to execute arbitrary commands as the Liquidsoap process user when recording ends.
AI Analysis
Technical Summary
AzuraCast through version 0.23.x contains a command injection vulnerability (CWE-78) in the Liquidsoap config generation for live recording. The flaw is due to failure to properly quote the streamer username in process.run calls. Authenticated users with Streamers and Profile permissions can supply a username containing shell metacharacters, which leads to arbitrary command execution under the Liquidsoap process user context upon recording closure.
Potential Impact
Successful exploitation allows an authenticated user with specific permissions to execute arbitrary commands on the server with the privileges of the Liquidsoap process user. This can lead to full compromise of the affected system, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Streamers and Profile permissions to trusted users only and avoid using special shell characters in usernames.
