CVE-2023-38885Network attack vector

State-changing actions via missing request-intent verification

Published Nov 20, 2023 · Updated Oct 21, 2024

Cross-site request forgery in OS4ED openSIS Classic Community Edition 9.0 allows remote attackers to perform state-changing actions. The application accepts state-changing requests throughout its web interface without verifying that the authenticated user intentionally initiated them. Exploitation requires an authenticated user to load attacker-controlled content, and resulting actions execute with that user's privileges.
