Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to an error when handling .scf scrips that are opened by the browser from the local filesystem. A remote attacker can trick the victim into launching a specially crafted .scf script that then initiates network requests from the operating system to the malicious server. A remote attacker can obtain potentially sensitive information including NTLM credentials.

Note, the vulnerability affects Windows installations only.
