This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. This vulnerability is reported in versions prior to 6.0.4. 2) Input passed via the "reportreason" and "modnotes" parameters in Shout Reports is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site if malicious data is viewed. This vulnerability is reported in versions prior to 6.0.6. SOLUTION: Update to version 6.0.6. PROVIDED AND/OR DISCOVERED BY: 1) Avram Marius Gabriel. 2) Reported by the vendor.
