CVE-2025-34054: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in AVTECH IP camera, DVR, and NVR Devices
An unauthenticated command injection vulnerability exists in AVTECH DVR devices via Search.cgi?action=cgi_query. The use of wget without input sanitization allows attackers to inject shell commands through the username or queryb64str parameters, executing commands as root. Exploitation evidence was observed by the Shadowserver Foundation on 2025-01-04 UTC.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-34054) involves improper neutralization of special elements in OS commands (CWE-78) in AVTECH IP camera, DVR, and NVR devices. Specifically, the Search.cgi endpoint accepts parameters that are passed to wget without sanitization, enabling unauthenticated attackers to inject arbitrary shell commands executed as root. Multiple firmware versions are affected. The vulnerability was publicly disclosed in mid-2025 with a maximum CVSS score, indicating critical severity. There is no indication of an available patch or vendor advisory detailing remediation.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary commands on affected AVTECH devices with root privileges. This can lead to full system compromise, unauthorized control, data theft, or device manipulation. The vulnerability affects multiple firmware versions of AVTECH IP cameras, DVRs, and NVRs. Exploitation evidence was observed, confirming active attempts or successful attacks in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to affected devices, especially blocking access to the Search.cgi endpoint from untrusted networks. Consider isolating vulnerable devices and monitoring for unusual activity. Do not rely on generic mitigations; focus on limiting exposure of the vulnerable CGI interface.
