Description Jan Lieskovsky 2012-07-13 10:54:51 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2012-3382 to the following vulnerability:

Cross-site scripting (XSS) vulnerability in the ProcessRequest function in mcs/class/System.Web/System.Web/HttpForbiddenHandler.cs in Mono 2.10.8 and earlier allows remote attackers to inject arbitrary web script or HTML via a file with a crafted name and a forbidden extension, which is not properly handled in an error message.
