Loading vulnerability…
CVE-2012-4956 is a heap-based buffer overflow in NFRAgent.exe in Novell File Reporter 1.0.2. The flaw is triggered when the agent processes an SRS record containing an excessively large number of VOL elements, causing a heap memory corruption condition. A remote attacker can send a crafted request to the exposed Novell File Reporter agent and exploit the overflow to achieve arbitrary code execution. The available advisory context indicates this issue is one of multiple critical vulnerabilities affecting the product.

This repository contains a single Metasploit auxiliary module targeting a heap overflow vulnerability (CVE-2012-4956) in Novell File Reporter Agent (NFRAgent.exe). The exploit is a denial-of-service (DoS) attack that sends a specially crafted HTTP POST request to the /FSF/CMD endpoint on the target, using a large number of <VOL> XML elements to overflow a heap buffer. The module is written in Ruby and leverages Metasploit's HttpClient and DoS auxiliary mixins. It is designed to crash the NFRAgent.exe process, resulting in a service outage, but does not provide code execution or shell access. The exploit is effective against NFR Agent 1.0.4.3 (File Reporter 1.0.2) running on Windows, with the default port 3037 and SSL enabled. The repository structure is typical for a Metasploit module, with the exploit logic contained in a single Ruby file.
