CISA Adds One Known Exploited Vulnerability to Catalog
This article is contributed. See the original author and article here.
CISA has added one new vulnerability 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.

Cisco Releases Security Updates for RV Series Routers
This article is contributed. See the original author and article here.
Cisco has released security updates to address vulnerabilities in Cisco Small Business RV160, RV260, RV340, and RV345 Series Routers. A remote attacker could exploit some of these vulnerabilities to take control of an affected system. For updates addressing lower severity vulnerabilities, see the Cisco Security Advisories page.
CISA encourages users and administrators to review Cisco advisory cisco-sa-sb-mult-vuln-CbVp4SUR and apply the necessary updates.
