[原文]Cross-site scripting (XSS) vulnerability in ppcal.cgi in PPCal Shopping Cart 3.3.0 and earlier allows remote attackers to inject arbitrary web script or HTML via the (1) stop and (2) user parameters.
PPCal Shopping Cart contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'stop' and 'user' parameters upon submission to the 'ppcal.cgi' script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
OSVDB is not aware of a solution for this vulnerability.

No exploit is required.
