CVE-2025-27724Public exploit

Local administrator escalation via writable login.php

Published Jul 28, 2025 · Updated Nov 3, 2025

Privilege escalation in MedDream PACS Premium 7.3.3.840 allows local users to gain Windows administrator rights by altering login.php. Weak NTFS permissions let any account with login access insert shell commands into login.php, which the web interface reloads as NT AUTHORITY\SYSTEM. A local login is required; execution adds an attacker-controlled account to the local Administrators group with full host control.
