A vulnerability was found in TrueConf Server 4.3.7. It has been classified as problematic. Affected is some unknown functionality of the file /admin/group/list/. The manipulation of the argument checked_group_id with an unknown input leads to a cross site scripting vulnerability (Reflected). CWE is classifying the issue as CWE-80. The software receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This is going to have an impact on integrity. An attacker might be able to inject arbitrary html and script code into the web site. This would alter the appearance and would make it possible to initiate further attacks against site visitors.
