CISA Adds Six Known Exploited Vulnerabilities to Catalog

Published: May 19, 2025

This Alert Is From CISA

CISA works with partners to defend against today’s threats and collaborate to build a more secure and resilient infrastructure for the future. CISA is the operational lead for federal cybersecurity and the national coordinator for critical infrastructure security and resilience. We are designed for collaboration and partnership. Learn about our layered mission to reduce risk to the nation’s cyber and physical infrastructure.

CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. 

  • CVE-2025-4427 Ivanti Endpoint Manager Mobile (EPMM) Authentication Bypass Vulnerability
  • CVE-2025-4428 Ivanti Endpoint Manager Mobile (EPMM) Code Injection Vulnerability
  • CVE-2024-11182 MDaemon Email Server Cross-Site Scripting (XSS) Vulnerability
  • CVE-2025-27920 Srimax Output Messenger Directory Traversal Vulnerability
  • CVE-2024-27443 Synacor Zimbra Collaboration Suite (ZCS) Cross-Site Scripting (XSS) Vulnerability
  • CVE-2023-38950 ZKTeco BioTime Path Traversal Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. 

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.
