DescriptionCVE.org

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.

Analysis

Technical ContextAI

Command injection allows an attacker to execute arbitrary OS commands on the host system through a vulnerable application that passes user input to system shells. This vulnerability is classified as OS Command Injection (CWE-78).

RemediationAI

Avoid passing user input to system commands. Use language-specific APIs instead of shell commands. If unavoidable, use strict input validation and escaping.
