CVE-2025-34056: 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 IP camera, DVR, and NVR devices via the PwdGrp.cgi endpoint, which handles user and group management operations. Authenticated users can supply input through the pwd or grp parameters, which are directly embedded into system commands without proper sanitation. This allows for the execution of arbitrary shell commands with root privileges.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-34056) involves improper neutralization of special elements in OS commands (CWE-78) within AVTECH IP camera, DVR, and NVR devices. Specifically, the PwdGrp.cgi endpoint accepts user-supplied input for password and group parameters without adequate sanitization, allowing authenticated users to execute arbitrary shell commands with root privileges. This can lead to full system compromise. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no user interaction, and privileges required, with high impact on confidentiality, integrity, availability, and scope.
Potential Impact
Successful exploitation allows an authenticated attacker to execute arbitrary commands on the affected device with root privileges. This can lead to complete device compromise, unauthorized access to sensitive data, disruption of device functionality, and potential pivoting within the network. The critical CVSS score reflects the severity of this impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected devices to trusted users only and monitor for suspicious activity. Avoid exposing the management interface to untrusted networks. Follow AVTECH's official channels for updates on patches or mitigations.
