Hmailserver Exploit Github Access

: While technically a Microsoft Outlook vulnerability, hMailServer is often used as the backend mail server in labs to demonstrate this "critical" bug. Attackers can use scripts like Xaitax's PoC to bypass SPF/DKIM/DMARC checks and send malicious emails that leak NTLM hashes or achieve remote code execution.

Historically, the PHPWebAdmin component—a web-based management tool for hMailServer—has been plagued by file inclusion vulnerabilities.

All GitHub repositories containing PoC exploits for hMailServer explicitly include disclaimers for educational and ethical testing purposes only. For instance, the CVE-2024-21413 PoC repository by Madhav-MKNC states: "This repo is intended for educational and ethical testing purposes only. Unauthorized scanning, testing, or exploiting of systems is illegal and unethical".

: Vulnerabilities in the page parameter of index.php and the hmail_config[includepath] parameter in initialize.php allowed for sensitive information disclosure or full system compromise. : Using path traversal or LFI vulnerabilities to

The GitHub disclosure highlights the importance of responsible vulnerability disclosure. By making the exploit public, the researcher aimed to:

file, potentially granting access to other hMailServer admin consoles. hMailEnum Proof of Concept (PoC) mojibake-dev/hMailEnum : Vulnerabilities in the page parameter of index

: A Python script that abuses CVE-2024-21413, specifically designed for TryHackMe lab environments using hMailServer with configured inboxes for attacker@monikerlink.thm and victim@monikerlink.thm

While older vulnerabilities may seem less threatening, organizations running legacy versions of hMailServer remain at risk. affects the IMAP server in hMailServer 4.4.1, allowing remote authenticated users to cause a denial of service (resource exhaustion or daemon crash) via a long series of IMAP commands.
