CVE-2010-20119 affects CommuniCrypt Mail versions up to and including 1.16. The vulnerability is a stack-based buffer overflow in the ANSMTP.dll and AOSMTP.dll ActiveX controls, specifically in the AddAttachments() method. The method does not properly validate the length of attacker-supplied input strings before copying them into a fixed-size stack buffer. Supplying an overly long string can overflow the buffer and corrupt adjacent stack memory, including structured exception handler data, resulting in control-flow corruption and potential arbitrary code execution in the context of the hosting process.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in the CommuniCrypt Mail 1.16 ANSMTP.dll/AOSMTP.dll ActiveX control (CVE-2010-20119). The exploit is delivered via a malicious HTML page served by the Metasploit framework, which instantiates the vulnerable ActiveX control in Internet Explorer and triggers the overflow by passing an overly long string to the AddAttachments() method. The module allows the attacker to execute arbitrary code (Metasploit payloads) on the victim's Windows XP system. The main fingerprintable endpoint is the CLSID of the vulnerable ActiveX control (F8D07B72-B4B4-46A0-ACC0-C771D4614B82), and the exploit specifically targets the ANSMTP.dll and AOSMTP.dll files. The repository is structured as a single Ruby file within the Metasploit framework's exploit modules directory.
