This can be exploited to manipulate SQL queries by injecting arbitrary code. 2) An error within the template selection mechanism can be exploited to force the application to render using a restricted view. Successful exploitation requires that the application uses "action:" within its routes. Note: This vulnerability only affects version 3.0.0 and later. 3) The content type handling does not properly sanitise certain input before returning it to the user. This can be exploited to insert arbitrary HTTP headers, which are included in a response sent to the user. Note: This vulnerability only affects version 2.3.x. 4) The "strip_tags" function does not properly sanitise certain input, which can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 5) The escaping mechanism does not properly handle certain Unicode sequences, which can be exploited to bypass the escaping mechanism and e.g. conduct cross-site scripting attacks. SOLUTION: Update to version 2.3.14 or 3.0.10. PROVIDED AND/OR DISCOVERED BY: 1) Reported by the vendor. The vendor credits: 2) Jan M.
