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.

Detection: Detecting and Blocking Threats at a National Laboratory The days of the "do-it-yourself" cult of cyberattacks using free software have passed. There is broad understanding among CIOs and CISOs that an effective cyber security program cannot be implemented without commercial technology and services.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Apache Struts vulnerability being exploited in the wild (CVE-2013-2251)
Description: A remote code execution vulnerability was announced two weeks ago in the popular Apache Struts2 framework, and the Sourcefire VRT has directly observed exploitation in the wild in multiple locations since the announcement. Attacks appear to be highly automated, and are thus likely to be widespread in the field. Administrators are urged to ensure their systems are patched immediately.
Reference:
http://struts.apache.org/release/2.3.x/docs/s2-016.html
Snort SID: 27243 - 27245
ClamAV: N/A

Title: Remote command execution on many SIM cards via binary SMS
Description: German group Security Research labs has pre-announced a weakness in the cryptographic algorithms used by as many as 1/8 of the world's SIM cards, which can be used to spoof over-the-air update packets, in order to run arbitrary commands and thus deploy malware. Details are scarce at this time, but the group is slated to present their research at Black Hat in Las Vegas next week.
Reference:

Snort SID: N/A
ClamAV: N/A

Title: "Cookiebomb" attacks discovered in the wild
Description: A new obfuscation technique by the authors of popular exploit kits such as Blackhole dubbed "Cookiebombing" has been recently observed in the wild. The concept - which separates the obfuscated code into a separate file by stuffing it into a cookie instead of directly into the infected JavaScript - is an interesting new development in the perpetual arms race between kit authors and security vendors, and may present complications for certain types of detection devices.
Reference:

Snort SID: 27229
ClamAV: N/A

Title: FBI-themed ransomware hitting Mac OS X users
Description: A recent campaign of malware targeting OS X users with threat of federal prosecution and a locked computer unless they pay $300 uses an interesting new technique - a popup that takes 150 clicks to make vanish and the browser's "restore from crash" feature to guarantee that even a force-quit of the browser won't fix the problem. Infected sites do not actually attempt to drop a binary on the user's system, presumably because such a level of complexity is not necessary to get users to fall for the scam.

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-2013-1017
Title: Apple Quicktime 7 Invalid Atom Length Buffer Overflow
Vendor: Apple
Description: Buffer overflow in Apple QuickTime before 7.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted dref atoms in a movie file.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2011-4166
Title: HP Managed Printing Administration jobAcct Remote Command Execution
Vendor: HP
Description: Directory traversal vulnerability in the MPAUploader.Uploader.1.UploadFiles method in HP Managed Printing Administration before 2.6.4 allows remote attackers to create arbitrary files via crafted form data.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID: CVE-2013-3163
Title: Microsoft Internet Explorer CBlockElement Use-after-Free Vulnerability
Vendor: Microsoft
Description: Microsoft Internet Explorer 8 through 10 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Internet Explorer Memory Corruption Vulnerability," a different vulnerability than CVE-2013-3144 and CVE-2013-3151.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2013-3660
Title: Microsoft Windows "win32k!EPATHOBJ::pprFlattenRec" Privilege
Escalation Vulnerability
Vendor: Microsoft
Description: The EPATHOBJ::pprFlattenRec function in win32k.sys in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012, and Windows RT does not properly initialize a pointer for the next object in a certain list, which allows local users to obtain write access to the PATHRECORD chain, and consequently gain privileges, by triggering excessive consumption of paged memory and then making many FlattenPath function calls.
CVSS v2 Base Score: 6.9 (AV:L/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2013-2460
Title: Java Applet ProviderSkeleton Insecure Invoke Method
Vendor: Oracle
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)
