Exploit Github Repack: Hmailserver

Several older versions of HmailServer's PHPWebAdmin component (prior to 5.6.8) suffered from blind SQL injection in the index.php parameter handling. This allowed unauthenticated attackers to dump the database—including password hashes (DEFAULT: SHA256 of the password with a salt).

Using a GitHub repository with exploit code for CVE-2023-2255, the attacker was able to create a malicious .odt file that added the user "maya" to the Administrators group when opened. This demonstrates how hMailServer can serve as an entry point in multi-stage attacks where multiple vulnerabilities are chained together to achieve full system compromise. hmailserver exploit github

hMailServer is a popular, free, open-source e-mail server for Microsoft Windows. It is widely used by small-to-medium businesses (SMBs) and ISPs due to its lightweight footprint and ease of administration. However, its popularity also makes it a frequent target for security researchers and malicious actors. GitHub hosts numerous proof-of-concept (PoC) exploits, vulnerability scanners, and automated scripts targeting hMailServer. This demonstrates how hMailServer can serve as an
