CVE-2025-34101: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Serviio Media Server
An unauthenticated command injection vulnerability exists in Serviio Media Server versions 1.4 through 1.8 on Windows, in the /rest/action API endpoint exposed by the console component (default port 23423). The checkStreamUrl method accepts a VIDEO parameter that is passed unsanitized to a call to cmd.exe, enabling arbitrary command execution under the privileges of the web server. No authentication is required to exploit this issue, as the REST API is exposed by default and lacks access controls.
AI Analysis
Technical Summary
An unauthenticated OS command injection vulnerability (CWE-78) exists in Serviio Media Server versions 1.4 through 1.8 on Windows platforms. The issue occurs in the /rest/action API endpoint exposed by the console component on the default port 23423. Specifically, the checkStreamUrl method accepts a VIDEO parameter that is passed directly and unsanitized to cmd.exe, enabling attackers to execute arbitrary commands with the privileges of the web server process. The REST API lacks authentication and access controls by default, allowing remote exploitation without credentials. This vulnerability is tracked as CVE-2025-34101 and has a CVSS 4.0 base score of 9.3, reflecting its critical impact. No patch or vendor advisory has been published yet, and no known exploits have been observed in the wild.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary OS commands on the affected Windows server with the privileges of the Serviio Media Server web process. This can lead to full system compromise, data theft, or disruption of service. The lack of authentication and default exposure of the vulnerable API endpoint significantly increases the attack surface and risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the /rest/action API endpoint (default port 23423) to trusted users only, or disable the console component if possible. Monitor vendor communications for updates and apply patches promptly once available.
