An issue in Dede CMS v.5.7.118 allows a remote attacker to obtain sensitive information via the str parameter of the file_manage_control.php component
AnalysisAI
Information disclosure in Dede CMS 5.7.118 allows remote unauthenticated attackers to retrieve sensitive data via the 'str' parameter in the file_manage_control.php component. No active exploitation has been confirmed, but a public write-up with exploit details is available on a Gitee repository.
Technical ContextAI
The vulnerability resides in the PHP-based 'file_manage_control.php' script, part of the file management functionality of Dede CMS. The 'str' parameter is likely used to specify file paths without proper sanitisation, leading to path traversal or direct file disclosure. This aligns with CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), where an attacker can read arbitrary files from the server, such as configuration files containing database credentials or other secrets.
RemediationAI
No vendor-released patch has been identified. As a workaround, restrict network access to the file_manage_control.php endpoint via web server configuration (e.g., .htaccess deny or IP whitelisting), or disable the file management component if not essential. Input validation for the 'str' parameter should be implemented to block directory traversal sequences. These mitigations may affect the legitimate file management functionality.
