TOP VULNERABILITY THIS WEEK: A mass exploitation campaign using a public

script recently released on the Full-Disclosure list hit Plesk servers
worldwide this week, with security researchers confirming that
compromised systems have already been used in other attacks. While there
is some dispute about which versions of Plesk are vulnerable,
administrators are urged to ensure the patch for CVE-2012-1823 is
applied to their underlying Apache servers, as it provides the mechanism
by which the Plesk exploits are gaining code execution.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Mass Plesk exploit hits hole left by CVE-2012-1823
Description: Exploit code was dropped on the Full-Disclosure mailing
list last Friday by known researcher Kingcope, who claimed that it was
a 0-day attack against the popular Plesk server management system. Other
members of the list verified that it is, instead, simply a new vector
for targeting CVE-2012-1823, a major remote code execution bug in PHP.
Mass attacks have been confirmed in the wild, with security researchers
noting that compromised systems were being used in other attacks within
a matter of days.

Title: Microsoft releases month’s patches
Description: Microsoft this Tuesday released its standard monthly
patches, covering 23 CVEs across 5 distinct bulletins. In addition to
the local kernel vulnerability disclosed by Google researcher Tavis
Ormandy in mid-May, the patches include a fix for a remotely exploitable
issue in Microsoft Office (CVE-2013-1331) that Microsoft notes has been
exploited in the wild. As always, system administrators should update
their machines as soon as feasible.

Title: New Pwn2Own Java vulnerability hits Metasploit - CVE-2013-1488
Description: Another Java remote code execution vulnerability from this
year’s Pwn2Own contest has had its first public exploit released in
Metasploit this week. Researcher James Forshaw, who had discussed the
bug in some detail in an April blog entry, is responsible for the
Metasploit module. While patches have been available since April,
systems administrators are urged to verify the deployment of those
patches, as exploits have presumably already begun in the wild.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM

This is a list of recent vulnerabilities for which exploits are
available. System administrators can use this list to help in
prioritization of their remediation activities. The Qualys Vulnerability
Research Team compiles this information based on various exploit
frameworks, exploit databases, exploit kits and monitoring of internet
activity.

ID: CVE-2013-1311
Title: Microsoft Internet Explorer textNode Use-After-Free
