Summary
CVE-2025-67752 is a high-severity Improper Certificate Validation (CWE-295) vulnerability in Open-Emr Openemr. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Adversary-in-the-Middle (T1557); ranked at the 14th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-67752 affects OpenEMR, a free and open source electronic health records and medical practice management application, specifically in versions prior to 7.0.4. The vulnerability resides in the HTTP client wrapper (oeHttp/oeHttpRequest), which disables SSL/TLS certificate verification by default (verify: false). This misconfiguration exposes all external HTTPS connections to man-in-the-middle (MITM) attacks, impacting communications with government healthcare APIs and user-configurable external services, with a potential to compromise Protected Health Information (PHI). The issue is classified under CWE-295 (Improper Certificate Validation) and carries a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).
An attacker capable of positioning themselves between the OpenEMR instance and external HTTPS endpoints—such as through network control, compromised routers, or ISP-level interception—can exploit this vulnerability. No user privileges or interaction are required, though high attack complexity is needed due to the MITM prerequisites. Successful exploitation allows the attacker to intercept, read, modify, or inject data in transit, leading to high confidentiality, integrity, and availability impacts, particularly the exposure or alteration of sensitive PHI during API interactions.
The OpenEMR security advisory (GHSA-2g6h-725p-pqhp) and associated fix in commit 22f8e53e5769a88b7a16cb223bd197d044c84e5a detail mitigation by enabling certificate verification in version 7.0.4. Security practitioners should upgrade to OpenEMR 7.0.4 or later, review and secure external service configurations, and monitor network traffic for signs of MITM activity.

Vulnerability Data
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 7.0.4, OpenEMR's HTTP client wrapper (`oeHttp`/`oeHttpRequest`) disables SSL/TLS certificate verification by default (`verify: false`), making all external HTTPS connections vulnerable to man-in-the-middle…

Mitigating Controls (NIST 800-53 r5) AI
PKI certificate issuance and acquisition under an approved policy establishes the trusted roots and processes needed for correct validation.
Protecting session authenticity depends on cryptographic mechanisms whose trust depends on correct certificate validation.
Requiring confidentiality and integrity protection of transmitted data drives use of properly validated certificates in protocols such as TLS.

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.
Certificate-based authentication of users/services/hardware directly depends on correct validation.
Proper certificate validation is a core mechanism for protecting data-in-transit confidentiality and integrity.
Secure development practices explicitly include implementing correct certificate validation logic.
Assessing authenticity/integrity of acquired software often relies on code-signing certificate validation.
Identity assertions conveyed via certificates require validation to be verified.
