CISA Adds Six Known Exploited Vulnerabilities to Catalog
CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.
CVE-2023-20887 VMware Aria Operations for Networks Command Injection Vulnerability
CVE-2020-35730 Roundcube Webmail Cross-Site Scripting (XSS) Vulnerability
CVE-2020-12641 Roundcube Webmail Remote Code Execution Vulnerability
CVE-2021-44026 Roundcube Webmail SQL Injection Vulnerability
CVE-2016-9079 Mozilla Firefox, Firefox ESR, and Thunderbird Use-After-Free Vulnerability
CVE-2016-0165 Microsoft Win32k Privilege Escalation Vulnerability
These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note: To view other 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 Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (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.

Barracuda Networks Releases Update to Address ESG Vulnerability
Barracuda Networks has released an update to their advisory addressing a vulnerability—CVE-2023-2868—in their Email Security Gateway Appliance (ESG). According to Barracuda, customers should replace impacted appliances immediately.
CISA urges organizations to review the Barracuda advisory and for all impacted customers to follow the mitigation steps as well as hunt for the listed indicators of compromise (IOCs) to uncover any malicious activity. For more information, see Mandiant’s advisory on Barracuda ESG Zero-Day Vulnerability (CVE-2023-2868) Exploited Globally by Aggressive and Skilled Actor.
Note: Customers who used enterprise privileged credentials for management of their Barracuda appliance (such as Active Directory Domain Admin or similar) should take immediate incident investigation steps to validate the use and behavior of all credentials used on the appliance. It is of utmost importance to verify that threat actors have not compromised customer enterprise networks via this entry vector.
CISA, FBI, and MS-ISAC Update Joint CSA on Progress Telerik Vulnerabilities
Today, CISA, the Federal Bureau of Investigation (FBI), and Multi-State Information Sharing and Analysis Center (MS-ISAC) released an update for joint Cybersecurity Advisory (CSA) Threat Actors Exploit Progress Telerik Vulnerability in U.S. Government IIS Server.
This iteration of the CSA—now renamed Threat Actors Exploit Progress Telerik Vulnerabilities in Multiple U.S. Government IIS Servers—is based on the forensic analysis and identified exploitation of CVE-2017-9248 at an additional FCEB agency. Activity identified at this agency is separate from the CVE-2019-18935 exploitation listed in the original publication; analysis is provided as context for existing vulnerabilities within Telerik UI for ASP.NET AJAX. Further, this update provides a timetable and context of unattributed APT actor activity that highlights events, including identified malicious files.
CISA, FBI, and MS-ISAC encourage network defenders to review this update and refer to the accompanying Malware Analysis Report, MAR-10443863-1.v1 CVE-2017-9248 Exploitation in U.S. Government IIS Server for analysis of the newly identified malicious files.
