9.0

CVSS v3.1

Official Description

Buffer overflow in the RTSP Packet Handler in AVTECH AVN801 DVR with firmware 1017-1003-1009-1003 and earlier, and possibly other devices, allows remote attackers to cause a denial of service (device crash) and possibly execute arbitrary code via a long string in the URI in an RTSP SETUP request.

Technical Analysis

CVE-2013-4980 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2013-4980. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
