CVE-2023-54347: OpenEMR 7.0.1 Authentication Brute Force Mitigation Bypass
OpenEMR 7.0.1 contains an authentication brute force vulnerability that allows attackers to bypass rate limiting protections by sending repeated login attempts to the main login endpoint. Attackers can submit POST requests with authUser and clearPass parameters to systematically test username and password combinations without account lockout restrictions.
Security readout for executives and security teams
Plain-English summary
OpenEMR 7.0.1 has a weakness in login brute-force protection. An attacker may repeatedly try username and password combinations without the expected account lockout or throttling. For organizations running OpenEMR, especially internet-facing healthcare systems, this raises the risk of account compromise through credential guessing.
Executive priority
Treat this as a high-priority exposure review for any OpenEMR 7.0.1 system. The main business risk is unauthorized access from password guessing, which is especially sensitive in healthcare environments handling patient data.
Technical view
CVE-2023-54347 is a CWE-307 improper restriction of excessive authentication attempts in OpenEMR 7.0.1. The CVSS v4.0 score is 8.7. Sources describe unauthenticated, network-accessible repeated login attempts bypassing rate-limit protections. The cited impact is primarily confidentiality through potential credential compromise.
Likely exposure
Most exposed organizations are those running OpenEMR 7.0.1 with a reachable login page, especially public internet deployments. Exposure depends on version, accessibility, and authentication controls around the OpenEMR instance.
Exploitation context
A public ExploitDB reference is cited, indicating exploit information is publicly available. The CVE is not listed as CISA KEV in the provided data, and no cited source confirms active exploitation.
Researcher notes
The source bundle identifies OpenEMR 7.0.1 only. No official patch version or vendor mitigation is named in the provided sources. Public exploit material is referenced, but active exploitation is not established by KEV or the cited sources.
Mitigation direction
Check OpenEMR and advisory sources for fixed releases or official mitigation.
Prioritize upgrade away from 7.0.1 if vendor guidance identifies a fixed version.
Restrict public access to OpenEMR login pages where operationally possible.
Use external throttling or access controls if available in your environment.
Monitor authentication failures and investigate abnormal login patterns.
Validation and detection
Inventory OpenEMR deployments and confirm whether version 7.0.1 is present.
Identify which OpenEMR login pages are internet-accessible.
Review authentication logs for high-volume failed login attempts.
Check vendor and advisory pages for updated affected-version guidance.
Confirm compensating controls limit repeated authentication attempts before OpenEMR.

CWE-307: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references authentication or credential exposure, so valid-account and credential-access review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
