TOP VULNERABILITY THIS WEEK: A major information disclosure

vulnerability impacting users of the popular W3 TotalCache for Wordpress
plugin was announced this week, with all files touched by the caching
server being publicly available on the Internet by default with no
authentication. The author of the plugin is currently working on a fix,
but administrators can take simple action in the interim to reduce their
exposure.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Wordpress W3 TotalCache Information disclosure
Description: A security researcher has discovered that, by default, the
popular W3 TotalCache plugin for Wordpress leaves cache files in
directories readable by the web server, with indexing enabled. That
allows for trivial web searches of all cached files of impacted servers,
including database session information, password-restricted data, etc.
At the time of writing, approximately 1.19 million results were returned
with appropriate Google searches, demonstrating the scope of the issue.
Impacted administrators should immediately disable indexing on all W3
TotalCache directories, and look for a patch that the author of the
product is currently working on.

Title: NVidia Display Driver “Christmas 0-day”
Description: Proving that information security never sleeps, a security
researcher in the UK released exploit code for a new NVidia display
driver on PasteBin on Christmas Day. While the has stated on this
Twitter feed that it is likely “not wormable”, the issue is clearly
serious, and is likely to be addressed directly by NVidia soon. As the
exploit uses an SMB pipe, in the interim concerned users should ensure
that they are using a firewall to protect their systems from as much
exposure to Windows SMB protocols as possible without impacting
business.

Title: AutoIt Trojan observed in the wild

observed in the wild recently. The malware uses an encoded backdoor
channel to decrease the likelihood of detection.
