CISA has added a new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.
- CVE-2025-22457 Ivanti Connect Secure, Policy Secure and ZTA Gateways Stack-Based Buffer Overflow Vulnerability
These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.
CISA urges organizations to apply the mitigations outlined in CISA's instructions linked below, which include conducting hunting activities, taking remediation actions if applicable, and applying updates before returning a device to service.
- Security Update: Pulse Connect Secure, Ivanti Connect Secure, Policy Secure and Neurons for ZTA Gateways
- CISA Mitigation Instructions for CVE-2025-22457
Organizations should report incidents and anomalous activity to CISA's 24/7 Operations Center at Report@cisa.gov or (888) 282-0870. When available, please include the following incident information: date, time, and location of the incident; type of activity; number of affected individuals; type of equipment used for the activity; the name of the reporting company or organization; and a designated point of contact.
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 pose significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities 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 adding vulnerabilities to the catalog that meet the specified criteria.
