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.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Bulgarian Android SMSsend
Description: Researcher Dancho Danchev has released information about a new piece of Android Malware that is found by visiting a "popular Bulgarian website for branded watches". He also indicates that the watch website is not the only website being used to distribute this piece of malware. Users are to use caution when installing any piece of software, even from legit Android sites.

Snort SID: 25512
ClamAV: Andr.Trojan.SMSsend-1

Title: Java 7 Update 11 still has a flaw
Description: According to several research sites on the internet, Java 7 Update 11 is still vulnerable to several bugs. One of which has been highlighted on the Internet Storm Center as being a "complete Java security sandbox bypass". Information about these bugs is still being assessed and US-CERT has recommended that you completely disable Java in the browser.

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-2013-0422
Title: Oracle Java SE Security Bypass Vulnerability
Vendor: Oracle
Description: Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114. CVE-2013-0422 covers both the JMX/MBean and Reflection API issues. NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks. NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11. If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-4792
Title: Microsoft Internet Explorer CDwnBindInfo Object Use-After-Free Vulnerability
Vendor: Microsoft
Description: Use-after-free vulnerability in Microsoft Internet Explorer 6 through 8 allows remote attackers to execute arbitrary code via a crafted web site that triggers access to an object that (1) was not properly allocated or (2) is deleted, as demonstrated by a CDwnBindInfo object, and exploited in the wild in December 2012.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2013-0156
Title: Ruby on Rails XML Processor YAML Deserialization Code Execution
Vendor: rubyonrails.org
Description: active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-0432
Title: Novell NCP Pre-Auth Remote Root Exploit
Vendor: Novell
Description: Stack-based buffer overflow in the Novell NCP implementation in NetIQ eDirectory 8.8.7.x before 8.8.7.2 allows remote attackers to have an unspecified impact via unknown vectors.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-6066
Title: Freesshd Authentication Bypass
Vendor: freesshd.com
Description: freeSSHd.exe in freeSSHd through 1.2.6 allows remote attackers to bypass authentication via a crafted session, as demonstrated by an OpenSSH client with modified versions of ssh.c and sshconnect2.c.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
