Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2012-5961.

AI-analyzed exploit summary This Metasploit module exploits a buffer overflow in the `unique_service_name()` function of libupnp's SSDP processor, allowing remote code execution. It targets specific devices like Supermicro IPMI and stages the payload over a secondary TCP connection due to size limitations.

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 device) field in a UDP packet.
