CVE-2024-51740Network attack vector

Server-side request forgery via arbitrary class instantiation

Published Nov 5, 2024 · Updated Nov 5, 2024

Server-side request forgery in Combodo iTop allows remote authenticated users to send HTTP requests through the user portal. The user portal form manager instantiates an attacker-selected PHP class without verifying that it derives from the expected form-manager base class. Low-privileged portal access is required, and the server-originated request can interrupt service; no data access or modification is reported.
