CVE-2012-5963
CWE-119Published: January 31, 2013· Updated: Jun 16, 2026
Official Description
Stack-based buffer overflow in the unique_service_name function in ssdp/ssdp_server.c in the SSDP parser in the portable SDK for UPnP Devices (aka libupnp, formerly the Intel SDK for UPnP devices) 1.3.1 allows remote attackers to execute arbitrary code via a long UDN (aka uuid) field within a string that lacks a :: (colon colon) in a UDP packet.
Technical Analysis
CVE-2012-5963 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-2012-5963. 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.
