CVE-2012-5958 is a stack-based buffer overflow in the SSDP parser of the Portable SDK for UPnP Devices (libupnp, formerly Intel SDK for UPnP Devices) prior to 1.6.18. The flaw is in the unique_service_name function in ssdp/ssdp_server.c, where a crafted string in a UDP SSDP packet is not properly handled after a pointer subtraction, leading to stack memory corruption. A remote attacker can trigger the overflow via a specially crafted UDP packet, potentially resulting in arbitrary code execution in the context of the vulnerable UPnP service, or a crash/denial of service.

This repository contains a single Metasploit exploit module targeting a buffer overflow vulnerability (CVE-2012-5958) in the unique_service_name() function of the libupnp library's SSDP processor. The exploit is designed for devices using the Portable UPnP SDK, such as Supermicro IPMI (Intel SDK 1.3.1) and Axis Camera M1011 (UPnP/1.4.1). The module sends a specially crafted SSDP (Simple Service Discovery Protocol) M-SEARCH request to the target's UDP port 1900 (the standard UPnP multicast address), triggering a buffer overflow and enabling remote code execution. Due to payload size limitations on many embedded devices, the exploit stages the actual payload via a secondary TCP connection, the address and port of which are configurable (CBHOST and CBPORT). The module includes fingerprinting logic to identify compatible targets based on their SSDP responses. The code is written in Ruby and is structured as a standard Metasploit module, with options for target selection, payload configuration, and network parameters. The exploit is operational and provides remote command execution capabilities on vulnerable devices.
