Security readout for executives and security teams
Plain-English summary
This vulnerability affects Ivanti remote access and policy gateway products. A remote unauthenticated attacker could execute code on vulnerable systems. Because CISA lists CVE-2025-22457 in KEV, organizations should treat exposed Ivanti gateways as urgent business risk, especially where they protect VPN, access, or zero-trust entry points.
Executive priority
Immediate. This is a critical remote code execution issue in access infrastructure, and CISA KEV confirms exploitation. Patch or otherwise address affected appliances as a top operational security priority, then validate whether exposed systems show signs requiring incident response.
Technical view
CVE-2025-22457 is a stack-based buffer overflow, CWE-121, with CVSS 9.0. It affects Ivanti Connect Secure before 22.7R2.6, Policy Secure before 22.7R1.4, and ZTA Gateways before 22.8R2.2. The vulnerability is remotely reachable without authentication and can lead to remote code execution.
Likely exposure
Exposure is most likely in organizations running internet-accessible Ivanti Connect Secure, Ivanti Policy Secure, or Ivanti Neurons for ZTA gateways below the named fixed versions. These systems commonly sit on sensitive access paths, so compromise could affect authentication, remote access, and internal network trust boundaries.
Exploitation context
Active exploitation is supported by CISA KEV listing. The source bundle does not provide exploit mechanics, observed targets, or indicators. Treat unpatched affected appliances as potentially exposed, but avoid assuming compromise without logs, vendor checks, or incident response evidence.
Researcher notes
The provided evidence confirms affected products, fixed-version thresholds, unauthenticated remote code execution impact, CVSS 9.0, CWE-121, and KEV status. It does not include exploit details, vulnerable code paths, proof-of-concept status, or indicators, so validation should rely on vendor guidance and environment telemetry.
Mitigation direction
- Upgrade Connect Secure to 22.7R2.6 or later per Ivanti guidance.
- Upgrade Policy Secure to 22.7R1.4 or later per Ivanti guidance.
- Upgrade ZTA Gateways to 22.8R2.2 or later per Ivanti guidance.
- Check Ivanti’s advisory for any product-specific response instructions.
- Prioritize externally reachable appliances before internal-only deployments.
Validation and detection
- Inventory all Ivanti Connect Secure, Policy Secure, and ZTA Gateway instances.
- Confirm each appliance version against the affected and fixed releases.
- Identify whether any affected appliances are internet-facing.
- Review Ivanti advisory and CISA KEV entry for required response actions.
- Check security logs and incident records for suspicious activity around affected systems.
