Detailsinfo

A vulnerability classified as critical has been found in AVTECH IP Camera, DVR and NVR (the affected version unknown). This affects an unknown part of the file PwdGrp.cgi of the component System Command Handler. The manipulation of the argument pwd/grp with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.
