HTTP: HSC HCP URL Quote Script Execution
This signature detects attempts to exploit a known vulnerability in URL handling with the Microsoft Help and Support Center (HSC) when invoked with an hcp:// URL. Attackers, by embedding a quote (") character in the URL, can instruct HSC to load an arbitrary local file or remote Web page that can be used to execute scripts in the local zone.
Extended Description
Help and Support Center in Microsoft Windows XP SP1 does not properly validate HCP URLs, which allows remote attackers to execute arbitrary code via quotation marks in an hcp:// URL, which are not quoted when constructing the argument list to HelpCtr.exe.
