CVE-2024-40530Public exploitNetwork attack vector

Unauthenticated developer access via spoofed client IP

Published Aug 5, 2024 · Updated Mar 24, 2025

Authorization bypass in UAB Lexita PanteraCRM CMS 401.152 and 402.072 allows remote attackers to access restricted tools over HTTP. The user IP verification mechanism trusts a client-supplied X-Forwarded-For value of 127.0.0.1 and treats the request as local. No authentication is required; the bypass exposes the /dev developer interface, database user records, and user-selection login pages.
