CVE-2026-0853
📋 TL;DR
Certain A-Plus Video Technologies NVR models expose sensitive device status information through an unauthenticated debug page. This allows remote attackers to gather reconnaissance data about the system without authentication. Organizations using affected NVR models are vulnerable.

⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain detailed device status information that could facilitate further attacks, including identifying software versions, network configurations, and system state for targeted exploitation.
Likely Case
Unauthenticated attackers access device debug information, potentially revealing system details that aid in reconnaissance for subsequent attacks.
If Mitigated
With proper network segmentation and access controls, exposure is limited to internal networks only, reducing external attack surface.
🎯 Exploit Status
Exploitation requires only HTTP access to the debug page endpoint without authentication.
