15 new vulnerabilities added to the CISA catalog; administrators must update immediately

In its most recent statement, the Cybersecurity and Infrastructure Security Agency (CISA) added 15 new vulnerabilities to its Catalog of Known Exploited Vulnerabilities, a list of known security flaws that threat actors have exploited in recent attacks and that must be addressed by federal agencies in the U.S.

In Binding Operational Directive 22-01: “Significant Risk Reduction of Known Exploited Vulnerabilities, it is stated that all federal government agencies in the U.S. must address the vulnerabilities on this list by the deadline set by CISA in order to keep their systems protected.

The list of flaws in the catalog includes:

  • CVE-2021-36934: Microsoft Windows SAM local privilege escalation
  • CVE-2020-0796: Remote code execution in Microsoft SMBv3
  • CVE-2018-1000861: Deserialization of untrusted data in Jenkins Stapler
  • CVE-2017-9791: Incorrect input validation of Apache Struts 1
  • CVE-2017-8464: Remote code execution in Microsoft Windows Shell
  • CVE-2017-10271: Remote code execution of oracle WebLogic server
  • CVE-2017-0263: Privilege escalation in Microsoft Win32k
  • CVE-2017-0262: Remote code execution in Microsoft Office
  • CVE-2017-0145: Remote code execution in Microsoft SMBv1
  • CVE-2017-0144: Remote code execution in Microsoft SMBv1
  • CVE-2016-3088: Incorrect input validation in Apache ActiveMQ
  • CVE-2015-2051: Remote code execution on D-Link routers
  • CVE-2015-1635: Remote code execution in Microsoft HTTP.sys
  • CVE-2015-1130: Authentication evasion in Apple OS X
  • CVE-2014-4404: Buffer overflow based on Apple OS X heap storage

One of the most severe problems recently has to do with the flaw of remote code execution on D-Link DIR-645 routers; A couple of months ago, AT&T specialists discovered a new botnet identified as BotenaGo, which thanks to the exploitation of dozens of exploits was able to compromise millions of Internet of Things (IoT) devices.

Counting these 15 security flaws, the number of flaws in CISA’s Catalogue of Known Exploited Vulnerabilities reached 368.
