DescriptionCVE.org

A vulnerability was found in DedeCMS up to 5.7.2 and classified as critical. This issue affects some unknown processing of the file /include/dedetag.class.php of the component Template Handler. The manipulation of the argument notes leads to command injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

AnalysisAI

Command injection in DedeCMS up to 5.7.2 allows remote authenticated attackers to execute arbitrary commands via the 'notes' parameter in /include/dedetag.class.php. A public exploit exists, but no active exploitation has been confirmed. EPSS score is low (0.17%), indicating limited exploitation likelihood.

Technical ContextAI

The vulnerability is a command injection (CWE-74) in the template handler component of DedeCMS, a PHP-based content management system. The affected file /include/dedetag.class.php processes user-supplied input via the 'notes' argument without proper sanitization, allowing injection of system commands. CPE data confirms all versions up to 5.7.2 are affected.

RemediationAI

No official patch has been released by the vendor. As a workaround, restrict access to the /include/dedetag.class.php file via web server configuration (e.g., .htaccess deny) or disable the template handler feature if not required. Input validation on the 'notes' parameter should be implemented to block command injection characters. Monitor for updates from DedeCMS.
