Administrative changes via forged systems request

Published Aug 12, 2021 · Updated Aug 4, 2024

Cross-site request forgery in bycms 1.3 allows attackers to perform an unspecified administrative change through a crafted systems request. The admin.php/systems/index/module_id/70/group_id/1.html endpoint applies a captured state-changing request to the active administrator session. An administrator must be logged in and induced to run the proof-of-concept request; the disclosed result is an unspecified settings change.
