CVE-2011-10027 is a stack-based buffer overflow in AOL Desktop 9.6, specifically in the Tool\rich.rct component while parsing .rtx files. The flaw is triggered by an overly long string embedded in a hyperlink tag within a crafted .rtx file. Based on the provided description, the vulnerable condition is caused by unsafe strcpy operations that copy attacker-controlled data into a fixed-size stack buffer without proper bounds checking. Successful exploitation can occur when a victim opens the malicious .rtx file, leading to memory corruption and potential arbitrary code execution.

This repository contains a Metasploit module that exploits a buffer overflow vulnerability (CVE-2011-10027) in AOL Desktop 9.6's Tool\rich.rct component. The exploit works by generating a malicious .rtx file containing an overly long hyperlink tag, which, when opened by a user in AOL Desktop 9.6, triggers a buffer overflow due to unsafe use of strcpy. This allows for arbitrary code execution with the privileges of the user. The module supports multiple targets, including Windows XP SP3 and Windows 7, with specific return addresses and ROP chains for NX bypass. The payload is customizable using Metasploit's payload system, typically allowing for reverse shells or Meterpreter sessions. The only fingerprintable endpoint is the malicious .rtx file itself, which must be delivered to and opened by the victim. The repository structure is typical for Metasploit, with the exploit logic contained in a single Ruby file under the appropriate modules directory.
