Description
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.
Analysis
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.
Technical Context
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 Improper Input Validation (CWE-20).
Affected Products
Affected: AVTECH IP camera
Remediation
Avoid passing user input to system commands. Use language-specific APIs instead of shell commands. If unavoidable, use strict input validation and escaping.
