CVE-2020-20943Public exploitNetwork attack vector

Forced article publication via crafted request

Published Dec 27, 2021 · Updated Aug 4, 2024

Cross-site request forgery in Qibosoft 7.0 allows remote attackers to force authenticated users to publish articles via a crafted URL. The /member/post.php endpoint processes a crafted postnew article-submission request in the victim session without effective CSRF validation. A victim must be signed in and induced to visit the URL; successful exploitation publishes attacker-chosen content under that user’s authority.
