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: Exploit code released for recently patched Java vulnerabilities was weaponized by exploit-kit authors within a matter of days over the past week, after publication by the PacketStorm bug bounty program. The vulnerabilities are now being hit in the wild by a variety of popular exploit kits; users are urged to verify that they have the latest patches applied immediately.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Recent Java exploits rapidly weaponizing in the wild
Description: Exploit code for a group of Java vulnerabilities patched in Oracle's June 2013 patch release has been made public over the last two weeks by the PacketStorm bug bounty program, and exploit kit authors and other malicious actors have been quick to weaponize the code and begin using it in the wild. Noted exploit kit researcher Kaffeine has already confirmed the presence of one or both exploits in half a dozen distinct kits, a particularly rapid uptake rate for an already-patched set of bugs. As always, administrators are urged to ensure that all systems under their control are properly patched.

ClamAV: Java.Exploit.CVE_2013_2465, Java.Exploit.CVE_2013_2459

Title: Denial of service in BIND in the wild
Description: A recently announced vulnerability in the popular BIND DNS service is being exploited in the wild, according to notes in the ISC vulnerability announcement included with their official patches. The issue, which can be exploited with a single packet, impacts the entire version 9 code base, and will hit default configurations there. Administrators should patch immediately, or upgrade to BIND 10 if possible, as several versions of the BIND 9 code base are past end-of-life and will not be patched against this issue.

Snort SID: 27666
ClamAV: N/A

Title: New attacks against security of TLS announced
Description: Researchers presenting at the 22nd annual USENIX security symposium last week announced a pair of partial plaintext recovery attacks against TLS. While the issues require rapidly repeated original plaintext in order to work, the researchers showed practical cases where necessary conditions would occur, though stopped short of providing any proof-of-concept code. Given this and related attacks discovered over the course of the last few years, such as the BEAST attack, developers of web applications secured by TLS should consider adding randomization to their plaintext messages as a proactive security measure against further attacks in this vein.

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: Not Available
Title: Joomla! Unauthorised Uploads
Vendor: Joomla!
Description: Inadequate filtering leads to the ability to bypass file type upload restrictions. Affects Joomla! version 2.5.13 and earlier 2.5.x versions; and version 3.1.4 and earlier 3.x versions
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2013-2465

Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, 6 Update 45 and earlier, and 5.0 Update 45 and earlier, and OpenJDK 7, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to 2D.

Description: Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2013-2251

Description: Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, and OpenJDK 7, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Serviceability. NOTE: the previous information is from the June 2013 CPU. Oracle has not commented on claims from another vendor that this issue allows remote attackers to bypass the Java sandbox via vectors related to "insufficient access checks" in the tracing component.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
