A stack-based buffer overflow exists in POP Peeper versions 3.4.0.0 and earlier. The vulnerability is triggered when a remote POP3 server sends an excessively long Date header, which is improperly handled by Imap.dll, leading to a buffer overflow condition. This can allow an attacker controlling a malicious POP3 server to execute arbitrary code on the client system.

This repository contains a single Metasploit module (modules/exploits/windows/misc/poppeeper_date.rb) that exploits a stack buffer overflow vulnerability in POP Peeper v3.4 (CVE-2009-1029). The exploit works by running a malicious POP server (default port 110) that sends a specially crafted 'Date:' header to a connecting POP Peeper client. The buffer overflow allows the attacker to execute arbitrary code on the client system. The module leverages Metasploit's payload system, allowing for customizable payloads up to 750 bytes, and uses SEH (Structured Exception Handler) overwrite techniques. The exploit is fully weaponized and integrated into the Metasploit framework, making it easy to use and adapt. The only fingerprintable endpoint is the TCP server listening on port 110. The code is well-structured, with clear separation of server setup, client interaction, and payload delivery.
This repository contains a single Metasploit module (modules/exploits/windows/misc/poppeeper_uidl.rb) that exploits a stack buffer overflow vulnerability (CVE-2009-1029) in POP Peeper v3.4, a Windows POP3 email client. The exploit works by acting as a malicious POP3 server (listening on TCP port 110) and delivering a specially crafted UIDL response to the client. When a vulnerable POP Peeper client connects and processes the malicious UIDL string, a SEH-based buffer overflow is triggered, allowing the attacker to execute arbitrary code on the client system. The module supports customizable payloads up to 750 bytes, with specific bad characters filtered out. The exploit is operational and leverages Metasploit's payload and handler infrastructure. The only fingerprintable endpoint is the TCP server on port 110, which mimics a POP3 service to attract vulnerable clients.
