@Risk: Security Alert
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.

MOST POPULAR MALWARE FILES 3/5/2013 - 3/12/2013

TOP VULNERABILITY THIS WEEK: A new Linux worm is rapidly spreading in the wild, covertly dropping a new copy of the Apache binary on infected systems and using them to quietly inject the Blackhole exploit kit. Administrators are urged to carefully check their systems for signs of compromise to the Apache binary, and to secure CPanel installations tightly, or keep them off of the public Internet where possible.

Title: CDorked worm spreads through Linux servers, dropping Blackhole Description: A new virus specifically targeting Linux systems with CPanel installed, known as Linxu/CDorked, is currently making its way through the Internet, dropping Blackhole exploit kits on infected systems after replacing their copy of the local Apache server binary. System administrators are urged to patch their systems to current levels, and to disable remote access to CPanel except where strictly necessary.
Snort SID: 26527-26532
ClamAV: Linux/CDorked.A

Title: Multiple vulnerabilities in DLink IP cameras
Description: A slew of serious, remotely exploitable vulnerabilities were announced in DLink IP cameras this week, including default passwords and arbitrary command injection without authentication. Owners of these cameras are urged to immediately disable remote access to them wherever possible, and apply current firmware updates in all cases. Reference:
Snort SID: 1122, 26559
ClamAV: N/A

Title: WordPress brute force scanners spiking in the wild
Description: A rash of scanners brute-forcing their way into poorly secured WordPress installations has been detected in the wild within the last few weeks, rising to heretofore unseen levels of activity. Once inside, the scanners typically drop web shells disguised as GIF files, along with other malicious content such as exploit kits and the like. Administrators are urged to ensure the use of secure, non-default passwords for all WordPress installations. Reference:
Snort SID: 23114, 26557
ClamAV: N/A

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-2013-2423
Title: Java Applet Reflection Type Confusion Remote Code Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK 7, allows remote attackers to affect integrity via unknown vectors related to HotSpot. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from the original researcher that this vulnerability allows remote attackers to bypass permission checks by the MethodHandles method and modify arbitrary public final fields using reflection and type confusion, as demonstrated using integer and double fields to disable the security manager.
CVSS v2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:N/I:P/A:N)

ID: CVE-2013-1362
Title: Nagios Remote Plugin Executor Arbitrary Command Execution
Description: A remote exploitation of an input validation error vulnerability in versions prior to 2.14 of Nagios, as included in various vendors' operating system distributions, could allow attackers to execute arbitrary commands on the targeted host.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID: CVE-2013-0632
Title: Adobe ColdFusion APSB13-03 Remote Exploit
Vendor: Adobe
Description: Adobe ColdFusion 9.0, 9.0.1, 9.0.2, and 10 allows remote attackers to bypass authentication and possibly execute arbitrary code via unspecified vectors, as exploited in the wild in January 2013.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2013-1080
Title: Novell ZENworks Configuration Management Remote Execution
Vendor: Novell
Description: The web server in Novell ZENworks Configuration Management (ZCM) 10.3 and 11.2 does not properly perform authentication for zenworks/jsp/index.jsp, which allows remote attackers to conduct directory traversal attacks, and consequently upload and execute arbitrary programs, via a request to TCP port 443.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2013-1493
Title: Oracle Java SE JVM 2D Subcomponent Remote Code Execution
Vulnerability (Oracle Security Alert for CVE-2013-1493)
Vendor: Oracle
Description: The color management (CMM) functionality in the 2D component in Oracle Java SE 7 Update 15 and earlier, 6 Update 41 and earlier, and 5.0 Update 40 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (crash) via an image with crafted raster parameters, which triggers (1) an out-of-bounds read or (2) memory corruption in the JVM, as exploited in the wild in February 2013.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
