CVE-2011-1213 is an integer underflow vulnerability in the lzhsr.dll component of Autonomy KeyView, as used in IBM Lotus Notes prior to 8.5.2 FP3. The vulnerability is triggered by a crafted header in a .lzh attachment, which causes an integer underflow leading to a stack-based buffer overflow. This can be exploited by a remote attacker to execute arbitrary code in the context of the application processing the attachment. The issue is also referenced as SPR PRAD88MJ2W.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2011-1213) in IBM Lotus Notes versions 8.0.x through 8.5.2 FP2 on Windows. The exploit works by generating a specially crafted .lzh file (default name: msf.lzh) containing a malicious payload. When a user opens this file as an email attachment in Lotus Notes, the vulnerability is triggered, allowing arbitrary code execution. The module supports two targets: one for non-DEP and one for DEP-enabled environments, using SEH and ROP techniques respectively. The payload is user-selectable and is encoded into the malicious file. The only endpoints involved are the generated .lzh file and the internal filename 'poc.txt' within the archive. The repository is a typical Metasploit exploit module written in Ruby, with all logic contained in a single file.
This repository contains a single Metasploit module (modules/exploits/windows/lotus/lotusnotes_lzh.rb) that exploits a stack buffer overflow vulnerability (CVE-2011-1213) in IBM Lotus Notes versions 8.0.x through 8.5.2 FP2 on Windows. The exploit works by sending a specially crafted .lzh file as an email attachment via SMTP to a Lotus Notes user. When the victim opens the attachment, the malformed LZH file triggers a buffer overflow, allowing the attacker to execute arbitrary code. The module supports two targets: one for non-DEP and one for DEP-enabled systems, using SEH and ROP techniques respectively. The payload is customizable and leverages Metasploit's payload system, typically resulting in a reverse shell or Meterpreter session. The exploit requires user interaction (the victim must open the attachment) and a permanent listener to catch the session. The only fingerprintable endpoint is the malicious .lzh file delivered via email. The code is written in Ruby and is structured as a standard Metasploit exploit module.
