@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 TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: DSL routers contain hard-coded "XXXXairocon" credentials
Description: CERT/CC has released an advisory warning users of
hard-coded credentials in several DSL routers. The advisory states that
"DSL routers, including the ASUS DSL-N12E, DIGICOM DG-5524T, Observa
Telecom RTA01N, Philippine Long Distance Telephone (PLDT) SpeedSurf
504AN, and ZTE ZXV10 W300 contain hard-coded credentials that are
useable in the telnet service on the device." CERT/CC recommends that
users "enable firewall rules so the telnet service of the device is not
accessible to untrusted sources" and to also "enable firewall rules that
block SNMP on the device."
Reference:
http://www.kb.cert.org/vuls/id/950576
Snort SID: Detection pending
Title: Remote Code Execution in Dolphin Browser for Android
Description: An advisory has been released detailing a remote code
execution vulnerability in the Dolphin Browser for Android. An attacker
with a privileged location on a network can "modify the functionality
of downloading and applying new themes for the browser." Exploitation
of this vulnerability would result in a capacity to perform an arbitrary
file write, which can be used and turned into code execution within the
context of 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-2015-0816
Title: Mozilla Firefox "resource:// document" Design Error Privilege
Escalation Vulnerability
Vendor: Mozilla Firefox
Description: Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6,
and Thunderbird before 31.6 do not properly restrict resource: URLs,
which makes it easier for remote attackers to execute arbitrary
JavaScript code with chrome privileges by leveraging the ability to
bypass the Same Origin Policy, as demonstrated by the resource: URL
associated with PDF.js.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:N/I:P/A:N)
ID: CVE-2015-0802
Title: Mozilla Firefox Privileged Window Design Error Security Bypass
Vulnerability
Vendor: Mozilla Firefox
Description: Mozilla Firefox before 37.0 relies on docshell type
information instead of page principal information for Window.webidl
access control, which might allow remote attackers to execute arbitrary
JavaScript code with chrome privileges via certain content navigation
that leverages the reachability of a privileged window with an
unintended persistence of access to restricted internal methods.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:N/I:P/A:N)
ID: CVE-2014-6332

Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1,
Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT
Gold and 8.1 allows remote attackers to execute arbitrary code via a
crafted web site, as demonstrated by an array-redimensioning attempt
that triggers improper handling of a size value in the SafeArrayDimen
function, aka "Windows OLE Automation Array Remote Code Execution
Vulnerability."
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2015-5122

CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2015-5119
Title: Adobe Flash ActionScript 3 ByteArray Use-After-Free Vulnerability
Vendor: Adobe
Description: Use-after-free vulnerability in the ByteArray class in the
ActionScript 3 (AS3) implementation in Adobe Flash Player 13.x through
13.0.0.296 and 14.x through 18.0.0.194 on Windows and OS X and 11.x
through 11.2.202.468 on Linux allows remote attackers to execute
arbitrary code or cause a denial of service (memory corruption) via
crafted Flash content that overrides a ValueOf function, as exploited
in the wild in July 2015.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2015-3090

Adobe AIR before 17.0.0.172, Adobe AIR SDK before 17.0.0.172, and Adobe
AIR SDK & Compiler before 17.0.0.172 allow attackers to execute
arbitrary code or cause a denial of service (memory corruption) via
unspecified vectors, a different vulnerability than CVE-2015-3078,
CVE-2015-3089, and CVE-2015-3093.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2015-1701
Title: Microsoft Windows Privilege Escalation Vulnerability
Vendor: Microsoft
Description: Win32k.sys in the kernel-mode drivers in Microsoft Windows
Server 2003 SP2, Vista SP2, and Server 2008 SP2 allows local users to
gain privileges via a crafted application, as exploited in the wild in
