DescriptionCVE.org

A vulnerability was detected in light0011 cms c774dce31c6df0055568a8d5c53d964d99be199d/f72cf46f601efb2a0618c3814cc2f61380b38930. This issue affects some unknown processing of the file App/Common/Conf/config.php of the component Debug Mode. The manipulation of the argument DB_DEBUG results in information disclosure. It is possible to launch the attack remotely. The exploit is now public and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Information disclosure in light0011 CMS exposes database debug output to unauthenticated remote attackers by manipulating the DB_DEBUG argument processed by the Debug Mode component in App/Common/Conf/config.php. The flaw allows network-accessible attackers to retrieve database diagnostic data - potentially including SQL query traces, schema details, or connection metadata - with no authentication and no user interaction required. …
