OUCH! Security Awareness

@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.

@RISK: The Consensus Security Vulnerability Alert

Vol. 13, Num. 07

Providing a reliable, weekly summary of newly discovered attack vectors, vulnerabilities with active exploits, and explanations of how recent attacks worked.

Title: Recently Patched Flash Vulnerabilities Actively Exploited In The Wild
Description: A pair of Adobe Flash vulnerabilities were patched last week, closing holes that were being exploited in the wild at the time of the patches. The attack payloads included creative new ways around common operating system level mitigations such as ASLR and DEP, making them particularly problematic for defenders. While attacks appear to have been limited in scope, particularly compared to last month's Java 0-day issues, high value targets in particular are urged to patch immediately.

ClamAV: BC.Exploit.CVE_2013_0633, SWF.Exploit.CVE_2013_0634

Title: Huge Microsoft Tuesday Includes Low-Level TCP/IP DoS
Description: Microsoft this week issued a huge set of patches, closing off 57 distinct CVEs in a total of 11 security notices. While many of these vulnerabilities will likely prove difficult to exploit in the wild, the VML memory corruption attack (CVE-2013-0030) is already being used for information disclosure in targeted attacks. Most likely to wreak havoc is the TCP/IP "Finshake" denial of service (CVE-2013-0075) - - discussed on underground forums as Microsoft having "nick'd up the stack" - which requires minimal attacker bandwidth and applies to any Microsoft operating system, regardless of which services are made available to the Internet. Administrators are urged to test and patch their systems as rapidly as feasible, given the size of this release.

Title: Microsoft, Symantec Take Down Bamital Botnet
Description: Continuing its winning streak in US federal courts, Microsoft's Digital Crimes Unit - in conjunction with security provider Symantec - executed a takedown of the massive Bamital botnet, which was responsible for major advertising fraud activities across the globe and distribution of copious amounts of peripheral malware. Infected users are now getting messages with cleanup instructions; unlike previous takedowns, such as DNSChanger, currently-infected systems are, however, can still be used on the Internet generally.

ClamAV: W32.Trojan.Bamital, WIN.Ransom.Lockscreen

Title: Security Firm Bit9 Compromised
Description: After failing to install its own application whitelisting product on all of its internal systems, security firm Bit9 revealed last week that it had been compromised, and that intruders had used its digital signing certificates to push malicious applications as if they were trusted code. While the firm has responded promptly and is working with all potentially impacted parties on cleanup, the compromise reiterates the necessity of following internal security policy in all circumstances, not just those where doing so is easy. Note that users of Sourcefire's FireAMP technology are protected from these malicious binaries through certificate revocation technology.

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-2012-5088
Title: Java Applet Method Handle Remote Code Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 7 and earlier allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Libraries.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-5076
Title: Java Applet AverageRangeStatisticImpl Remote Code Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 7 and earlier allows remote attackers to affect confidentiality, integrity, and availability, related to JAX-WS.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-5958
Title: Portable UPnP SDK unique_service_name() Remote Code Execution
Description: Stack-based buffer overflow in the unique_service_name function in ssdp/ssdp_server.c in the SSDP parser in the portable SDK for UPnP Devices (aka libupnp, formerly the Intel SDK for UPnP devices) before 1.6.18 allows remote attackers to execute arbitrary code via a UDP packet with a crafted string that is not properly handled after a certain pointer subtraction.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-3569
Title: VMWare OVF Tools Format String Vulnerability
Vendor: VMWare
Description: Format string vulnerability in VMware OVF Tool 2.1 on Windows, as used in VMware Workstation 8.x before 8.0.5, VMware Player 4.x before 4.0.5, and other products, allows user-assisted remote attackers to execute arbitrary code via a crafted OVF file.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
