CVE-2016-3351 is an information disclosure vulnerability affecting Microsoft Internet Explorer 9 through 11 and Microsoft Edge. A crafted website can expose information about the victim's system through MIME-type checks that reveal file-extension associations. AdGholas and GooNky exploited the vulnerability to fingerprint visitors and exclude systems associated with security researchers, virtual machines, and sandboxes from malvertising infection chains. Exploitation was observed as early as January 2014. Microsoft released patches on September 13, 2016.

An Internet Explorer information disclosure vulnerability observed alongside CVE-2016-3298 in a GooNky infection chain and associated with AdGholas exploitation. It enabled attackers to identify and filter security research environments. The cited disclosure states that Microsoft patched the vulnerability.
An information disclosure vulnerability in Microsoft Internet Explorer and Edge that exposes file-extension associations through MIME-type checks. AdGholas and GooNky used it to identify and avoid researchers, sandboxes, and analysis environments, selectively allowing other users to proceed through malvertising exploitation chains. The vulnerability supported long-running detection evasion before Microsoft patched it in September 2016.
