Last Chance: MacBook Air, Dell XPS 13 or $600 off with SANS Online Training Ends December 7

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.

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

CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2015-3090

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

CVSS v2 Base Score: 7.2 (AV:L/AC:L/Au:N/C:C/I:C/A:C)
