Last Day for MacBook Air, Dell XPS 13, or $600 Off with Online Training

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.

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-2013-3918
Title: Microsoft ActiveX Controls "InformationCardSigninHelper Class" Out-of-Bounds Memory Access Vulnerability Vendor: Microsoft
Description: A remote code execution vulnerability exists in the InformationCardSigninHelper Class ActiveX control. Specifically the issue occurs in the way "InformationCardSigninHelper Class" ActiveX control (icardie.dll) is loaded into Internet Explorer and causes system state corruption.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2013-3906
Title: Microsoft Graphics Component Could Allow Remote Code Execution
Vendor: Microsoft
Description: Remote exploitation of a memory corruption vulnerability in multiple Microsoft products could allow attackers to execute arbitrary code on the targeted host. The issue occurs with how the TIFF codec in Microsoft's graphics component handles crafted TIFF files. Processing crafted TIFF files can corrupt system memory and create an exploitable condition.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2012-1823
Title: PHP Group PHP CGI Query String Parameter Processing Remote Code Execution
Vendor: PHP
Description: sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before 5.4.2, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to execute arbitrary code by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'd' case.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID: Not Available
Title: D-Link Authentication Security Bypass Vulnerability
Vendor: D-Link
Description: A remote exploitation of a design error vulnerability in D-Link Systems Inc.'s routers could allow attackers to bypass authentication security restrictions. The router allows any user with a Web browser having the user agent string "xmlset_roodkcableoj28840ybtide" to gain access to the Web interface of the device without the requirement for any authentication credentials. Affects D-Link Firmware v1.13 and other versions may also be affected.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2013-2251
Title: Apache Struts 2 DefaultActionMapper Prefixes OGNL Code Execution
Vendor: Apache
Description: Apache Struts 2.0.0 through 2.3.15 allows remote attackers to execute arbitrary OGNL expressions via a parameter with a crafted (1) action:, (2) redirect:, or (3) redirectAction: prefix.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
