Technical Analysis
Liman core versions before 2.2.2 - 1103 contain an OS command injection vulnerability (CWE-20, CWE-78) in the log rotation configuration endpoint. The ip_address parameter is directly embedded into a shell command without sanitization, enabling shell escape through single-quote injection. This allows an authenticated administrator to execute arbitrary OS commands on the server. The vulnerability is fixed in version 2.2.2 - 1103.
Potential Impact
Successful exploitation allows an authenticated administrator to execute arbitrary operating system commands on the Liman server, potentially leading to full system compromise, data loss, or disruption of service. The vulnerability affects confidentiality, integrity, and availability as indicated by the CVSS vector.
Mitigation Recommendations
Upgrade Liman core to version 2.2.2 - 1103 or later, where this vulnerability is fixed. No other mitigation or workaround is documented. Patch status is confirmed fixed in 2.2.2 - 1103.
