[原文]Cross-site scripting (XSS) vulnerability in default.asp in FogBugz 4.029, and other versions before 4.0.33, allows remote attackers to inject arbitrary web script or HTML via the dest parameter in the pgLogon page.
FogBugz contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate 'dest' variable upon submission to the pgLogon.php script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known workarounds or upgrades to correct this issue. However, Fog Creek Software has released a patch to address this vulnerability.
