@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: VMware Releases Security Advisory for Denial-of-Service Vulnerability in Workstation and Fusion
Description: VMware has released a security advisory for CVE-2018-6957, a denial-of-service vulnerability in VMware Workstation, Fusion, and Player. This vulnerability manifests as a result of the hypervisor incorrectly handling large numbers of VNC sessions that are opened. VMware has released a software update that addresses this vulnerability.

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-2018-4878
Title: Adobe Flash Player Remote Code Execution Vulnerability (APSA18-01)
Vendor: Adobe
Description: A critical vulnerability exists in Adobe Flash Player 28.0.0.137 and earlier versions. Successful exploitation could potentially allow an attacker to take control of the affected system. Adobe is aware of a report that an exploit for CVE-2018-4878 exists in the wild and is being used in targeted attacks.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2017-10271
Title: Oracle WebLogic WLS Security Component Remote Code Execution
Vendor: Oracle
Description: Vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware (subcomponent: WLS Security). Supported versions that are affected are 10.3.6.0.0, 12.1.3.0.0, 12.2.1.1.0 and 12.2.1.2.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks of this vulnerability can result in takeover of Oracle WebLogic Server.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P)
ID: CVE-2017-17562
Title: EmbedThis GoAhead Remote Code Execution Vulnerability
Vendor: EmbedThis GoAhead
Description: Embedthis GoAhead before 3.6.5 allows remote code execution if CGI is enabled and a CGI program is dynamically linked. This is a result of initializing the environment of forked CGI scripts using untrusted HTTP request parameters in the cgiHandler function in cgi.c. When combined with the glibc dynamic linker, this behaviour can be abused for remote code execution using special parameter names such as LD_PRELOAD. An attacker can POST their shared object payload in the body of the request, and reference it using /proc/self/fd/0.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
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-2017-0145
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-2017-3881
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)
