Microsoft Internet Explorer 6 through 11 Arbitrary Code Execution
High Nessus Network Monitor Plugin ID 8240
This is a deprecated warning regarding the version of Microsoft Internet Explorer on the remote host; NNM cannot determine passively whether or not the browser has been patched.
Unpatched versions of Internet Explorer 6 through 11 contain a vulnerability that bypasses both of Windows' ASLP and DEP protections, though current attacks in the wild have been targeting versions 9 and onward. An attacker could leverage this to execute arbitrary code within the context of the user running the browser.
