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: Intel Releases Security Updates for Flaws Identified in CPU Chipsets

Description: Intel has released a security update to address several vulnerabilities that have been identified in the Management Engine, Server Platform Service, and Trusted Execution Engine. These updates address scenarios where an attacker could impersonate the ME/SPS/TXE, load and execute code outside the visibility of the user or operating system, or cause the system to crash. Affected platforms include 6th, 7th & 8th generation Core processors, Xeon E3-1200 v5 & v6 processors, and more.

Snort SID: Detection pending release of vulnerability information


Title: Oracle Releases Out-of-Band Security Update for Jolt Server Vulnerabilities in Oracle Tuxedo

Description: Oracle has released an out-of-band security update to address "CVE-2017-10269 and four other vulnerabilities affecting the Jolt server within Oracle Tuxedo." Two of the vulnerabilities are deemed critical and carry a CVSS score of 9.9 or 10.0. An attack who exploits these vulnerabilities could gain full access to data stored on system which leverage Oracle Tuxedo, such as PeopleSoft. Oracle has advised customers to applies the updates as soon as possible due to the severity of the vulnerabilities.

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-2017-8759

Title:     Microsoft .NET Framework Remote Code Execution Vulnerability

Vendor: Microsoft

Description: A remote code execution vulnerability exists when Microsoft .NET Framework processes untrusted input. Microsoft is aware of a report that an exploit for CVE-2017-8759 exists in the wild and is being used in targeted attacks.

Microsoft published a .NET security update to address this issue.

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


ID:     CVE-2017-9805

Title:     Apache Struts REST plugin Remote Code Execution (S2-052)

Vendor: Apache Struts

Description: The REST Plugin is using a XStreamHandler with an instance of XStream for deserialization without any type filtering and this can lead to Remote Code Execution when deserializing XML payloads.

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


ID:     CVE-2017-0037

Title:     Microsoft Internet Explorer Remote Code Execution (MS17-007)

Vendor: Microsoft

Description: Microsoft Internet Explorer 10 and 11 and Microsoft Edge have a type confusion issue in the Layout::MultiColumnBoxBuilder::HandleColumnBreakOnColumnSpanningElement function in mshtml.dll, which allows remote attackers to execute arbitrary code via vectors involving a crafted Cascading Style Sheets (CSS) token sequence and crafted JavaScript code that operates on a TH element.

CVSS v2 Base Score: 7.6 (AV:N/AC:H/Au:N/C:C/I:C/A:C)


ID:     CVE-2017-0145

Title:     Microsoft Windows SMB Remote Code Execution Vulnerability

Vendor: Microsoft

Description: The SMBv1 server in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607; and Windows Server 2016 allows remote attackers to execute arbitrary code via crafted packets, aka "Windows SMB Remote Code Execution Vulnerability." This vulnerability is different from those described in CVE-2017-0143, CVE-2017-0144, CVE-2017-0146, and CVE-2017-0148.

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


ID:     CVE-2017-0290

Title:     Microsoft Malware Protection Engine Remote Code Execution Vulnerability

Vendor: Microsoft

Description: NScript in mpengine in Microsoft Malware Protection Engine with Engine Version before 1.1.13704.0, as used in Windows Defender and other products, allows remote attackers to execute arbitrary code or cause a denial of service (type confusion and application crash) via crafted JavaScript code within any file scanned by this engine.  

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


ID:     CVE-2017-3881

Title:     Cisco IOS and IOS XE Software Cluster Management Protocol Remote Code Execution Vulnerability

Vendor: Cisco

Description: A vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device or remotely execute code with elevated privileges. The Cluster Management Protocol utilizes Telnet internally as a signaling and command protocol between cluster members. The vulnerability is due to the combination of two factors: (1) the failure to restrict the use of CMP-specific Telnet options only to internal, local communications between cluster members and instead accept and process such options over any Telnet connection to an affected device; and (2) the incorrect processing of malformed CMP-specific Telnet options. An attacker could exploit this vulnerability by sending malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections. An exploit could allow an attacker to execute arbitrary code and obtain full control of the device or cause a reload of the affected device. This affects Catalyst switches, Embedded Service 2020 switches, Enhanced Layer 2 EtherSwitch Service Module, Enhanced Layer 2/3 EtherSwitch Service Module, Gigabit Ethernet Switch Module (CGESM) for HP, IE Industrial Ethernet switches, ME 4924-10GE switch, RF Gateway 10, and SM-X Layer 2/3 EtherSwitch Service Module. Cisco Bug IDs: CSCvd48893.

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


ID:     CVE-2017-5638

Title:     Apache Struts2 Input Validation Code Execution Vulnerability

Vendor: Apache

Description: The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 mishandles file upload, which allows remote attackers to execute arbitrary commands via a #cmd= string in a crafted Content-Type HTTP header, as exploited in the wild in March 2017.

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


ID:     CVE-2016-7892

Title:     Adobe Flash Player Use-After-Free Code Execution Vulnerability

Vendor: Adobe

Description: Remote exploitation of a use-after-free vulnerability in Adobe's Flash Player could allow attackers to execute arbitrary code. Adobe is aware of a report that an exploit for CVE-2016-7892 exists in the wild, and is being used in limited targeted attacks.

CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
