Summary

CVE-2025-22459 is a medium-severity Improper Following of a Certificate's Chain of Trust (CWE-296) vulnerability in Ivanti Endpoint Manager. Its CVSS base score is 4.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Adversary-in-the-Middle (T1557); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-17 (Public Key Infrastructure Certificates) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SC-17 Public Key Infrastructure Certificates good match

SC-17 requires proper issuance and management of PKI certificates, which structurally enforces correct chain-of-trust validation.

SC-23 Session Authenticity partial match

Protecting session authenticity depends on cryptographic mechanisms whose trust depends on correct certificate validation.

SC-8 Transmission Confidentiality and Integrity partial match

Requiring confidentiality and integrity protection of transmitted data drives use of properly validated certificates in protocols such as TLS.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-03 mostly match
prevents

Proper service/hardware authentication requires correct certificate chain validation to a trusted root.

PR.DS-02 mostly match
prevents

Proper certificate validation is a core mechanism for protecting data-in-transit confidentiality and integrity.

PR.PS-06 mostly match
prevents

Secure development practices explicitly include implementing correct certificate validation logic.

ID.RA-09 partial match
prevents

Pre-acquisition authenticity checks may surface certificate issues but do not address runtime chain-following logic.

PR.AA-04 partial match
prevents

Verifying identity assertions includes ensuring certificate chains are followed correctly.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.24 Use of cryptography mostly match
prevents

Mandates proper use of cryptography including certificate validation and trusted roots.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect missing or incorrect certificate chain validation.

A.8.28 Secure coding partial match
prevents

Secure coding standards address correct certificate chain validation.

A.8.5 Secure authentication partial match
degrades

Requires secure authentication mechanisms that rely on valid certificate chains.

A.8.20 Networks security none match
mitigates

Network security controls often enforce TLS certificate validation.

A.8.21 Security of network services none match
mitigates

Secure network services depend on correct certificate chain validation.
