QCMS Content Detail Controllers.php self_Tmp sql injection

A security vulnerability has been detected in QCMS up to 6.0.6. This issue affects the function self_Tmp in the library Lib/Config/Controllers.php of the component Content Detail Page. Such manipulation of the argument ID leads to sql injection. The attack may be performed from remote. The exploit has been disclosed publicly and may be used. Router uses raw REQUEST_URI without URL decoding, so payloads must contain literal spaces - %20 never decodes before route parsing. The support team of the vendor was contacted early about this disclosure. Unfortunately, they responded just with profanity.

A vulnerability in QCMS version 6.0.5 allows authenticated users to read arbitrary files from the server due to insufficient validation of the "Name" parameter in the backend template editor. By manipulating the parameter, attackers can perform directory traversal and access sensitive files outside the intended template directory, potentially exposing system configuration, PHP source code, or other sensitive information.

QCMS version 3.0 has XSS via the title parameter to the /guest/index.html URI.

QCMS version 3.0 has XSS via the webname parameter to the /backend/system.html URI.
