CVE-2020-36007Public exploitNetwork attack vector

Sensitive-information disclosure via reflected cate_id XSS

Published Jun 3, 2021 · Updated Aug 4, 2024

Cross-site scripting in AppCMS 2.0.101 allows remote authenticated users to obtain other users’ sensitive information via crafted cate_id requests. The tpl_app.php and tpl_info.php handlers reflect the cate_id parameter into the response without adequate output encoding, allowing injected script execution in an administrator’s browser. Login to the administrative background is required, and the demonstrated consequence is browser-side data disclosure or action as the affected user rather than server-side code execution.
