2022 CWE Top 25 Most Dangerous Software Weaknesses

06/28/2022 10:00 AM EDT

Original release date: June 28, 2022

The Homeland Security Systems Engineering and Development Institute, sponsored by CISA and operated by MITRE, has released the 2022 Common Weakness Enumeration (CWE) Top 25 Most Dangerous Software Weaknesses list. The list uses data from the National Vulnerability Database to compile the most frequent and critical errors that can lead to serious vulnerabilities in software. An attacker can often exploit these vulnerabilities to take control of an affected system, obtain sensitive information, or cause a denial-of-service condition. This year’s list also incorporates updated weakness data for recent Common Vulnerabilities and Exposure records in the dataset that are part of CISA’s Known Exploited Vulnerabilities Catalog.

CISA encourages users and administrators to review the 2022 CWE Top 25 Most Dangerous Software Weaknesses and evaluate recommended mitigations to determine those most suitable to adopt.

CISA Adds Eight Known Exploited Vulnerabilities to Catalog  

06/27/2022 11:00 AM EDT

Original release date: June 27, 2022

CISA has added eight new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risk to the federal enterprise. Note: to view the newly added vulnerabilities in the catalog, click on the arrow in the “Date Added to Catalog” column, which will sort by descending dates.     

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known CVEs that carry significant risk to the federal enterprise. BOD 22-01 requires FCEB agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the Catalog that meet the specified criteria.
