Administrator authentication hijacking via undisclosed webapi CSRF
Published Jul 26, 2022 · Updated Sep 16, 2024
Cross-site request forgery in Synology Calendar before 2.3.4-0631 allows remote authenticated users to hijack administrator authentication. The flaw is in the webapi component, but Synology has not published the affected endpoint or the request-handling error that accepts the forged action. Exploitation requires a low-privileged authenticated account and administrator interaction, after which the attack crosses into the administrator's security context and can affect confidentiality, integrity, and availability.
