Description Jan Lieskovsky 2012-08-21 16:45:14 UTC
A cross-site scripting (XSS) flaw was found in the way 'langwiz' example script of GeSHi, a generic syntax highlighter, performed sanitization of certain HTTP GET / POST request variables (prior dumping their content). A remote attacker could provide a specially-crafted URL that, when visited would lead to arbitrary HTML or web script execution.
