AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions SEMCMS PHP version 3.4

Description A cross-site scripting (XSS) issue was found in the SEMCMS SeoAndTag.php file, specifically through the tag indexmetatit parameter when the Class parameter is set to "edit" and the CF parameter is set to "SeoAndTag". This allows for potential execution of malicious scripts.

Recommendations For SEMCMS PHP version 3.4, as a temporary workaround, consider restricting access to the SEMCMS SeoAndTag.php file or disabling the tag indexmetatit parameter in the affected API endpoint until a patch is available. Avoid using the tag indexmetatit parameter in the "/SEMCMS SeoAndTag.php?Class=edit&CF=SeoAndTag" endpoint until the issue is resolved.
