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
This vulnerability in Serviio Media Server (versions 1.4 to 1.8) on Windows involves improper neutralization of special elements in an OS command (CWE-78) within the /rest/action API endpoint. The checkStreamUrl method processes a VIDEO parameter that is directly passed to cmd.exe without sanitization, enabling unauthenticated attackers to execute arbitrary OS commands with the privileges of the web server. The REST API is exposed by default and lacks access controls, increasing the risk of exploitation. The CVSS 4.0 vector indicates network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary commands on the Windows host running Serviio Media Server with web server privileges. This can lead to full compromise of the affected system, including data theft, service disruption, or further network penetration. The vulnerability affects confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, it is recommended to restrict network access to the default port 23423 to trusted users only and disable or firewall the /rest/action API endpoint if possible. Monitor for unusual activity related to the Serviio Media Server. Do not expose the REST API to untrusted networks.
