TOP VULNERABILITY THIS WEEK: A trivially exploitable 0-day vulnerability

in the current version of Java was released late on Sunday night, and
is already being actively used in the field. No patch is currently
available, and is not scheduled until October 16; concerned security
researchers have released unofficial patches in the interim.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: CVE-2012-4681 - Java 0-day with no patch being actively exploited
in the wild
Description: A new Java vulnerability that allows for remote code
execution was released late Sunday night by security researchers,
including well-documented, easily modified proof-of-concept code. The
vulnerability has since been ported to Metasploit, and trusted sources
indicate that it will be rolled into the popular Blackhole exploit kit
immediately. The Sourcefire VRT has observed active in-the-wild
exploitation already; the nature of the bug makes it trivial to modify
the proof-of-concept code to add any weaponized payload of the
attacker’s choice. No official patch is currently available, and the
next scheduled Java patch release is October 16, nearly two months away;
an unofficial patch from a security researcher is now available for
those who are willing to apply it. Users are urged to disable Java in
all untrusted locations wherever possible until the release of an
official patch.

Title: CVE-2012-2109 - HP Operations Agent stack overflow
Description: A remote unauthenticated buffer overflow exists in the HP
Operations Agent, a widely deployed cross-platform system for monitoring
system health. While no public attacks exist, the Sourcefire VRT has
information indicating that private attacks exist and may be deployed
in targeted attacks. Users are urged to patch their systems immediately.

Title: Rebots malware injection campaign
Description: A large injection campaign dubbed “Rebots” after the remote
file being included has been active in the wild over the last several
weeks, targeting primarily WordPress blogs and other systems that can
easily have JavaScript code dropped into them. The campaign has dropped
a variety of payloads over time, and is likely to continue cycling
through distinct payloads as it evolves.

Title: New variants of Zbot emerging in the wild
Description: The Zbot/Zeus banking trojan family has been a popular
choice for criminals and fraudsters across the globe since 2010. Its
popularity is due in part to the professional support given to
purchasers by its developers, who are constantly working to avoid new
AV detection techniques. Recent updates to the kit have begun to emerge
in the wild across a number of exploits, and users are cautioned to
ensure that their AV and IDS solutions are up-to-date to handle this
latest variant.
