Name of the Vulnerable Software and Affected Versions DedeCMS version 7.5 SP2

Description The issue is related to the lack of protection measures for the web page structure in the select media.php component of the DedeCMS content management system. This can be exploited by a remote attacker to conduct cross-site scripting (XSS) attacks. The vulnerability is specifically found in the activepath, keyword, tag, fmdo=x&filename, CKEditor, and CKEditorFuncNum parameters.

Recommendations For DedeCMS version 7.5 SP2, consider disabling the select media.php component or restricting access to it until a patch is available. As a temporary workaround, avoid using the activepath, keyword, tag, fmdo=x&filename, CKEditor, and CKEditorFuncNum parameters in the affected component to minimize the risk of exploitation.
