Newsletters: @RISK

@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.

TOP VULNERABILITY THIS WEEK: A new Internet Explorer remote code execution vulnerability was disclosed on Tuesday this week, with Microsoft acknowledging targeted exploitation concurring already in the wild. The vulnerability, which depended on the loading of a Microsoft Office library loaded without ASLR for exploitation, has prompted a "Fix-It" mitigation already, although no out-of-cycle patch was forthcoming at the time of writing.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Internet Explorer 0-day flaw emerges, being used in targeted attacks
Description: Microsoft on Tuesday publicly announced that a new remote code execution vulnerability in all current versions of Internet Explorer was being used in targeted attacks in the wild. Tagged with CVE-2013-3893, the vulnerability takes advantage of memory corruption issues related to deleted objects, as do most modern IE bugs. Microsoft has provided a "Fix-It" workaround, and notes that EMET mitigates the vulnerability if enabled. At the time of writing, it was unclear whether Microsoft would issue an out-of-band patch for the issue, or await its next standard patch cycle for a full fix.

ClamAV: BC.Exploit.CVE_2013_3893

Title: Popular Django web framework trivially DoS-able via oversized passwords
Description: The Python-based Django web development framework - used by major sites such as Instagram, Mozilla, and Pinterest - released a patch this week to limit the size of passwords accepted by its authentication system, after a security researcher publicly disclosed that oversized passwords could lead to a denial of service due to the complexity of the password hashing algorithms involved. Though no proof-of-concept code exploits are available, administrators should assume active exploitation in the wild due to the simple nature of the vulnerability, and apply available patches immediately.

Title: Wordpress < 3.6.1 PHP object injection vulnerability disclosed
Description: A remote code execution vulnerability in Wordpress was announced last week by an independent security researcher in Belgium, who detailed a way to bypass the CMS system's built-in sanity checks on serialized data by way of MySQL's behavior of truncating characters in an input string following UTF-8 characters within a given range. The vulnerability - which is highly dependent on certain characteristics of the PHP code being called - is not exploitable in the core Wordpress system, but is noted by the researcher as being present in popular plugins. Administrators should ensure that their Wordpress core is up to the most current patch level.
