Detect Digiever DS-2105 Pro Missing Authorization Exploitation (CVE-2023-52163) in IBM QRadar
Detects exploitation of CVE-2023-52163, a missing authorization vulnerability (CWE-862) in Digiever DS-2105 Pro NVR devices. This KEV-listed vulnerability allows unauthenticated attackers to access restricted functionality or administrative interfaces without proper credential validation. Threat actors actively exploit exposed NVR devices for initial access, lateral movement, and persistence in OT/IoT environments.

Testing Methodology
Validate this detection against 3 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Unauthenticated Admin Endpoint Enumeration
Expected signal: HTTP GET requests to /cgi-bin/ and /admin/ paths from the test host IP to the NVR device on port 80, with no Authorization header present in the HTTP request headers
- Test 2RTSP Stream Access Without Authentication
Expected signal: Network connections to TCP/554 (RTSP) and TCP/80 from test host; HTTP requests to /cgi-bin/snapshot.cgi without authentication headers; potential RTSP DESCRIBE request in network capture
- Test 3Configuration Extraction via Unauthenticated API
Expected signal: Multiple HTTP GET requests to configuration and backup endpoints without Authorization headers; file download activity if 200 responses received; DNS lookups for NVR hostname from test system
