CVE-2021-41245Network attack vector

Cross-site request forgery via unchecked transaction token

Published Apr 5, 2022 · Updated Apr 22, 2025

Cross-Site Request Forgery in Combodo iTop before 2.7.6 allows remote attackers to alter data via crafted requests using invalid transaction tokens. The privUITransactionFile implementation accepts transaction files without binding them to the connected user, so a victim browser can submit a forged operation that the server treats as valid. Exploitation requires a logged-in victim to visit attacker-controlled content; impact is integrity loss through unauthorized changes, with no demonstrated confidentiality or availability effect.
