In very old versions, the administrator password was stored in the hMailServer.INI
If you are still running hMailServer, you are vulnerable to: Credential Theft: hmailserver exploit github
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). In very old versions, the administrator password was
This repository contains a Proof-of-Concept (PoC) demonstrating a vulnerability in hMailServer. Specifically, it targets [explain the mechanism, e.g., the way configuration files store obfuscated passwords or how the server handles specific SMTP commands]. Vulnerability Type: [e.g., Weak Password Obfuscation, CVE-2024-XXXXX] Specifically, it targets [explain the mechanism, e
: A potential RCE vulnerability ( Issue #276 ) was identified where a specifically crafted SMTP command sequence could inject shellcode onto the stack during data parsing. If successful, an attacker could take over the host with NT AUTHORITY\SYSTEM permissions.
This critical vulnerability allowed an authenticated administrator to execute arbitrary commands on the HmailServer host via the COM API's Utilities.Execute method. Although authentication is required, attackers often combine it with credential theft or session hijacking.
