[原文]Cross-site scripting (XSS) vulnerability in CGI wrapper for IP Calculator (IPCalc) 0.40 allows remote attackers to inject arbitrary web script or HTML via the URI (REQUEST_URI environment variable), which is used in the actionurl variable.
IPCalc contains a flaw that allows a remote cross site scripting (XSS) attack. This flaw exists because the application does not validate the REQUEST_URI parameter upon submission to the CGI. 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.
Upgrade to version 0.41 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
