TOP VULNERABILITY THIS WEEK: Network administrators were given another

reason to disable Java across their enterprises this week, as another
new Java 0-day was publicly disclosed last Friday. While the
vulnerability had been used for targeted attacks, and a patch was
released on Monday, it is likely to become widely exploited,
particularly in exploit kits, over the next few weeks.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Fresh Java 0-day hits, Oracle releases patch
Description: Described as “Yet another Java 0-day” by the organization
disclosing it, details emerged last Friday of a bug in the color
management portion of Java applets that Oracle said was “easily
exploitable” in the note it released on Monday to accompany its patches.
Attacks in the wild have been targeted to date, and initially
compromised sites were using C&C channels and malware samples associated
to the recent Bit9 breach, suggesting a coordinated campaign by those
using the exploit. Still, given the proliferation of exploit kits -
including a new one announced Monday that uses nothing but Java
vulnerabilities - it is only a matter of time before mass exploitation
occurs, and users are urged to patch immediately.

Title: MiniDuke malware targeting European governments, agencies
Description: A newly discovered piece of targeted malware dubbed
“MiniDuke” has been using CVE-2013-0640 - a PDF vulnerability discovered
in February - to drop particularly sneaky malware on European
governments and their agencies at locations across the world. The
malware uses Twitter to spread information about C&C channels, and
authors left taunting clues inside their binaries, including a reference
to the number 666 just before the decryption routine.

Title: 0-day exploit in the wild for Japanese word processor Ichitaro
Description: Trend Micro recently discovered an exploit in the wild for
popular Japanese word processing software Ichitaro. Similar to
vulnerabilities in Microsoft Office discovered in 2011, the program used
an improper path selection criteria for loading DLLs, and could easily
be tricked into loading a malicious DLL and executing arbitrary code on
the system. Patches for some versions of the software were made
available on March 5, while fixes for other versions are scheduled for
release on March 28.

Title: SAP NetWeaver remote code execution
Description: The SAP NetWeaver service is vulnerable to remote code
execution via malformed messages taking advantage of the
MSJ2EE_AddStatistics() function. Exploit code is publicly available, and
attacks are presumed to be occurring in the wild. Users should patch
their systems immediately.
