Server Message Block Potential Exploit

VUIT Security Advisory: Potential Exploit of Server Message Block (SMB)

Vanderbilt IT would like to bring the following information to the technical community’s attention, especially those who use any version of Microsoft Windows, a Microsoft server or Samba.

US-CERT has issued an advisory in response to a public report of a potential Server Message Block (SMB) vulnerability. This service is universally available for Windows systems, and legacy versions of SMB protocols could allow a remote attacker to obtain sensitive information from affected systems.

All administrators are advised to discontinue using SMBv1 and to disable client support on end-user systems.

VUIT has implemented protections at the perimeter firewall and will continue to monitor this situation closely.
