AVTECH DVR SSRF Vulnerability Scanner

AVTECH DVR devices are widely used in surveillance systems to manage and record video footage from CCTV cameras. They are utilized by organizations, businesses, and homeowners to enhance security and monitor activities. These devices allow for live viewing, recording, and playback of video feeds, making them integral components of security infrastructure. AVTECH DVRs are known for their reliability and ease of use, offering features such as motion detection and remote access. The vulnerability scanner is designed to protect these systems by identifying potential security risks.

The vulnerability scanner identifies a Server-Side Request Forgery (SSRF) issue in the AVTECH DVR's Search.cgi function. SSRF vulnerabilities allow attackers to abuse functionality on the server to read or update internal resources. In this case, the Search.cgi can be accessed directly without authentication, posing a risk of unauthorized access to and manipulation of camera devices within the network. This vulnerability could potentially allow attackers to reach internal services or execute arbitrary requests from the server's perspective.

The vulnerability resides in the Search.cgi script of AVTECH DVR devices, specifically within the cgi_query function. This script is responsible for scanning and accessing cameras in the local network. It does not properly validate user-supplied input, allowing external entities to initiate requests to internal systems. Attackers can exploit this by crafting malicious URLs to perform unauthorized actions, such as scanning for devices, accessing camera feeds, or manipulating device settings without proper authorization.

If exploited, this SSRF vulnerability could lead to unauthorized access to surveillance systems, allowing attackers to view or manipulate camera feeds, perform network scans from the device's perspective, and potentially gain access to other internal network resources. This could compromise the privacy and security of the monitored premises, lead to data breaches, and allow further attacks against the internal network.
