Summary
CVE-2023-2947 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Open-Emr Openemr. Its CVSS base score is 4.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Protocol or Service Impersonation (T1001.003); ranked in the top 0.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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-2023-2947 is a stored cross-site scripting vulnerability (CWE-79) affecting the OpenEMR electronic health records platform in the openemr/openemr repository prior to version 7.0.1. The flaw permits an attacker to persistently inject malicious script into application pages that are later rendered for other users, with a CVSS 3.1 base score of 4.8 reflecting network attack vector, low complexity, high privileges required, and changed scope.
An authenticated user holding high privileges can supply crafted input that is stored by the application and subsequently executed in the browsers of other users who view the affected content. Successful exploitation can result in limited confidentiality and integrity impacts such as session token theft or unauthorized actions performed in the context of the victim user, though availability is unaffected and user interaction is required.
Public references point to a specific commit (8d2d601) that addresses the issue and to the corresponding huntr.dev disclosure. The recommended mitigation is to upgrade OpenEMR to version 7.0.1 or later, which incorporates the corrective changes.
EPSS for the CVE has remained flat at its recorded peak of 0.5248 with no material post-disclosure rise.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing submits XSS payloads to web applications, detecting cross-site scripting flaws for subsequent remediation.
Validates web inputs to reject script-related content that could produce XSS.
Output validation against expected content can reject or sanitize script content in generated web pages, reducing XSS exploitability.
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.
Secure SDLC practices directly target introduction of XSS via coding standards/testing (mostly), yet the single broad outcome leaves many specific neutralization vectors unaddressed (partial).
Patching and EOL replacement can remediate known XSS instances in libraries or frameworks (partial) but do nothing to enforce input neutralization in application code (none).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
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.5.6 only promotes membership in groups to improve knowledge, receive alerts, and share information; it performs no action that stops XSS exploitation (or even the underlying neutralization defect) and is a pure dependency for other controls per the owner's labeling rule.
