Loading vulnerability…
A stack-based buffer overflow exists in the IMAP service of Mercur Messaging 5.0 SP3 and earlier. The vulnerability is triggered when a remote attacker sends an excessively long string to the LOGIN or SELECT command, resulting in a buffer overflow on the stack. This is distinct from CVE-2003-1177 and involves different attack vectors.

This repository contains a single Metasploit module: 'mercur_imap_select_overflow.rb', which exploits a stack-based buffer overflow vulnerability (CVE-2006-1255) in the Mercur v5.0 IMAP server SP3. The exploit targets Windows 2000 Server SP4 English and Windows 2000 Pro SP1 English platforms. The module leverages the Metasploit framework's IMAP support to connect to the target IMAP service (typically on TCP port 143), authenticate, and send a specially crafted 'SELECT' command that overflows a buffer, allowing execution of arbitrary code. The payload is customizable via Metasploit and can provide remote shell access or other capabilities. The exploit is weaponized, as it is part of the Metasploit framework and supports flexible payload selection. No hardcoded IP addresses or URLs are present; the only fingerprintable endpoint is the IMAP service itself.
This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability (CVE-2006-1255) in Atrium Mercur Messaging IMAP 5.0 SP3. The exploit is implemented in Ruby and leverages the Metasploit framework's TCP and egghunter modules. The vulnerability is exploited by sending a specially crafted IMAP LOGIN command to the service running on TCP port 143, resulting in arbitrary code execution. The module supports payloads with a small buffer space, using an egghunter to locate the shellcode in memory. The exploit targets Windows 2000 Pro SP4 English and Windows XP Pro SP2 English systems. The repository structure is typical for Metasploit modules, with the exploit code located in 'modules/exploits/windows/imap/mercur_login.rb'.
