Title
mathurvishal CloudClassroom-PHP-Project updatequery.php cross site scripting
Summary
A weakness has been identified in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. This affects an unknown function of the file updatequery.php. Executing a manipulation of the argument queryx can lead to cross site scripting. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The vendor was contacted early about this disclosure but did not respond in any way.
