Ivanti released security updates to address vulnerabilities (CVE-2025-0282, CVE-2025-0283) in Ivanti Connect Secure, Policy Secure, and ZTA Gateways. A cyber threat actor could exploit CVE-2025-0282 to take control of an affected system.

CISA has added CVE-2025-0282 to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

CISA urges organizations to hunt for any malicious activity, report any positive findings to CISA, and review the following for more information:

• Security Advisory Ivanti Connect Secure, Policy Secure & ZTA Gateways (CVE-2025-0282, CVE-2025-0283)

For all instances of Ivanti Connect Secure, Policy Secure, and ZTA Gateways, see the following steps for general hunting guidance:

1. Conduct threat hunting actions:  
   1. Run the In-Build Integrity Checker Tool (ICT). Instructions can be found here. 
   2. Conduct threat hunt actions on any systems connected to—or recently connected to—the affected Ivanti device.  
2. If threat hunting actions determine no compromise: 
   1. Factory reset the device and apply the patch described in Security Advisory Ivanti Connect Secure, Policy Secure & ZTA Gateways (CVE-2025-0282, CVE-2025-0283). 
   2. Monitor the authentication or identity management services that could be exposed. 
   3. Continue to audit privilege level access accounts. 
3. If threat hunting actions determine compromise: 
   1. Report to CISA and Ivanti immediately to start forensic investigation and incident response activities.  
   2. Disconnect instances of affected Ivanti Connect Secure products.  
   3. Isolate the systems from any enterprise resources to the greatest degree possible. 
   4. Revoke and reissue any connected or exposed certificates, keys, and passwords, to include the following: 
      1. Reset the admin enable password. 
      2. Reset stored application programming interface (API) keys. 
      3. Reset the password of any local user defined on the gateway, including service accounts used for auth server configuration(s).  
   5. If domain accounts associated with the affected products have been compromised: 
      1. Reset passwords twice for on premise accounts, revoke Kerberos tickets, and then revoke tokens for cloud accounts in hybrid deployments. 
      2. For cloud joined/registered devices, disable devices in the cloud to revoke the device tokens.
   6. After investigation, fully patch and restore system to service.

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 information regarding the incident: date, time, and location of the incident; type of activity; number of people affected; type of equipment used for the activity; the name of the submitting company or organization; and a designated point of contact.

4. MITIGATIONS

Tibbo recommends users update to Versions 6.40.02, 6.34.03, or latest version.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the Internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

CISA also recommends users take the following measures to protect themselves from social engineering attacks:

• Do not click web links or open attachments in unsolicited email messages.
• Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
• Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.

No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time.
