CVE-2025-34055: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in AVTECH IP camera, DVR, and NVR Devices
An OS command injection vulnerability exists in AVTECH DVR, NVR, and IP camera devices within the adcommand.cgi endpoint, which interfaces with the ActionD daemon. Authenticated users can invoke the DoShellCmd operation, passing arbitrary input via the strCmd parameter. This input is executed directly by the system shell without sanitation allowing attackers to execute commands as the root user.
AI Analysis
Technical Summary
An OS command injection vulnerability (CWE-78) exists in AVTECH DVR, NVR, and IP camera devices in the adcommand.cgi endpoint. Authenticated users can invoke the DoShellCmd operation with arbitrary input via the strCmd parameter, which is executed by the system shell as root without input sanitization. This vulnerability allows attackers with valid credentials to execute arbitrary commands on the affected device with root privileges, potentially compromising the device's security and control.
Potential Impact
Successful exploitation allows authenticated attackers to execute arbitrary OS commands as the root user on affected AVTECH devices. This can lead to full system compromise, including unauthorized access, data manipulation, device control, and disruption of services. The vulnerability severely impacts confidentiality, integrity, and availability of the devices.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected devices to trusted users only and monitor for suspicious activity related to the adcommand.cgi endpoint. Avoid exposing management interfaces to untrusted networks. Follow vendor communications for updates on patches or mitigations.
