@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data
A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.June 13, 2013
@RISK: The Consensus Security Vulnerability Alert
Vol. 13, Num. 24
Providing a reliable, weekly summary of newly discovered attack vectors, vulnerabilities with active exploits, and explanations of how recent attacks worked.=============================================================
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.
Snort SID: 22063
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.
Snort SID: 6700, 26843-26849, 26851-26853, 26867-26878, 26882-26890

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.
