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.
