CVE-2024-51545Public exploitNetwork attack vector

Unauthenticated account manipulation via trusted Host header

Published Dec 5, 2024 · Updated Dec 5, 2024

Authentication bypass in ABB ASPECT products 3.08.02 and earlier allows remote attackers to list, add, modify, or delete application users. The MIX AuthenticatedHttpServlet derives the remote address from the attacker-controlled Host header and treats localhost as implicitly authorized. Network access to port 7226 is sufficient, and arbitrary user or group changes can grant MIXAdmin access.
