Loading vulnerability…
CVE-2011-3494 describes multiple buffer overflow vulnerabilities in WinSig.exe, a component of eSignal 10.6.2425 and earlier. Specifically, remote attackers can trigger a stack-based buffer overflow by supplying a long StyleTemplate element in a QUO, SUM, or POR file, or a heap-based buffer overflow via a long Font->FaceName field. These vulnerabilities can be exploited to crash the application and potentially execute arbitrary code.

This repository contains a single Metasploit module targeting a buffer overflow vulnerability (CVE-2011-3494) in eSignal and eSignal Pro (version 10.6.2425.1208 and earlier) on Windows platforms. The exploit generates a malicious <StyleTemplate> file (with .quo, .sum, or .por extension) that, when opened by a vulnerable version of eSignal, triggers a buffer overflow and executes arbitrary code via an egghunter payload. The module allows the attacker to specify a custom payload (up to 1000 bytes, avoiding null bytes), which is delivered using Metasploit's payload generation capabilities. The attack vector is local, requiring the victim to open the crafted file. The repository is structured as a standard Metasploit exploit module, written in Ruby, and is operational with customizable payload support.
