CVE-2012-3382: Cross-site scripting (XSS) vulnerability in the ProcessRequest function in mcs/class/System.Web/System.Web/...

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.

Security readout for executives and security teams

This is an XSS flaw in older Mono web handling. A specially named forbidden file can cause an error page to include attacker-controlled script or HTML. The likely business impact is browser-side compromise of users who view that error page, not direct server takeover. Public sources do not show active exploitation. Exposure is most likely in legacy applications running Mono 2.10.8 or earlier with System.Web reachable by remote users. Systems using maintained Mono packages or not serving Mono System.Web applications are less likely exposed. The bundle’s structured affected-product fields are incomplete. Prioritize remediation where legacy Mono web apps are still reachable by users or the internet. This is not supported as actively exploited in the provided sources, but browser-side compromise risk justifies cleanup during normal vulnerability remediation cycles. Mitigation focus: Upgrade Mono or distro packages to versions containing the referenced fix.; Review openSUSE and Mandriva advisories for applicable package guidance.; Retire or isolate legacy Mono 2.10.8-and-earlier web applications..
