@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: Remote code execution bugs in Word, SMB disclosed as part of Patch Tuesday
Description: Microsoft released its monthly security update Tuesday, disclosing more than 120 vulnerabilities across its array of products. While none of the vulnerabilities disclosed have been exploited in the wild, users of all Microsoft and Windows products are urged to update their software as soon as possible to avoid possible exploitation. The security updates cover several different products including the VBScript engine, SharePoint file-sharing service and GDI+.

Title: Cisco patches vulnerabilities in IOS XE, affecting some industrial routers
Description: Cisco disclosed three critical vulnerabilities in its IOS and IOS XE software and industrial router group. Many of the alerts concern a command injection vulnerability that would allow an adversary to execute arbitrary code on the affected operating system. One of the most severe bugs could allow a remote attacker to obtain an authorization token on the affected system and execute their choice of IOx API commands on the device.

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-2020-9484
Title: Apache Tomcat Remote Code Execution Vulnerability
Vendor: Apache
Description: When using Apache Tomcat versions if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed.
CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2020-0796
Title: Microsoft Windows SMBv3 Client/Server Remote Code Execution Vulnerability
Vendor: Microsoft
Description: A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 3.1.1 (SMBv3) protocol handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server or client. To exploit the vulnerability against a server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3 server.
CVSS v3 Base Score: 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H)
ID: CVE-2020-3956
Title: VMware Cloud Director Code Injection Vulnerability
Vendor: VMware
Description: VMware Cloud Director do not properly handle input leading to a code injection vulnerability. An authenticated actor may be able to send malicious traffic to VMware Cloud Director which may lead to arbitrary remote code execution. This vulnerability can be exploited through the HTML5- and Flex-based UIs, the API Explorer interface and API access.
CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2020-13401
Title: Docker Engine IPv6 Address Spoofing Vulnerability
Vendor: Docker
Description: An issue exists in Docker Engine where an attacker in a container, with the CAP_NET_RAW capability, can craft IPv6 router advertisements, and consequently spoof external IPv6 hosts, obtain sensitive information, or cause a denial of service. A user is able to create containers with CAP_NET_RAW privileges on an affected cluster can intercept traffic from other containers on the host or from the host itself.
CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2020-1301
Title: Microsoft Windows SMB Remote Code Execution Vulnerability
Vendor: Microsoft
Description: A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server.
CVSS v3 Base Score: 7.5 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2020-1181
Title: Microsoft SharePoint Server Remote Code Execution Vulnerability
Vendor: Microsoft
Description: A remote code execution vulnerability exists in Microsoft SharePoint Server when it fails to properly identify and filter unsafe ASP.Net web controls. An authenticated attacker who successfully exploited the vulnerability could use a specially crafted page to perform actions in the security context of the SharePoint application pool process.
CVSS v3 Base Score: 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
ID: CVE-2020-1206
Title: Microsoft Windows SMBv3 Client/Server Information Disclosure Vulnerability
Vendor: Microsoft
Description: An information disclosure vulnerability exists in the way that the Microsoft Server Message Block 3.1.1 (SMBv3) protocol handles certain requests. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user's system. To exploit the vulnerability against a server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3 server. To exploit the vulnerability against a client, an unauthenticated attacker would need to configure a malicious SMBv3 server and convince a user to connect to it.
CVSS v3 Base Score: 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N)
