Description: Michael Ligh and Greg Sinclair have reported a vulnerability in FirePass, which can be exploited by malicious people to conduct cross-site scripting attacks. 1) Input passed to the "xcho" parameter in my.logon.php3 is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Successful exploitation requires the parameter is ROT13 encoded and the "crs" parameter is a valid corresponding CRC32 hash. 2) Some unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site via double "eval()" functions or within "<FP_DO_NOT_TOUCH>" tags.
