Deeper analysis
CVE-2023-2948 is a generic cross-site scripting vulnerability (CWE-79) affecting the OpenEMR electronic health records platform in the openemr/openemr GitHub repository prior to version 7.0.1. The flaw received a CVSS 3.1 score of 6.1 with network attack vector, low complexity, no required privileges, and required user interaction, along with changed scope that permits limited confidentiality and integrity impact.
An unauthenticated remote attacker can exploit the issue by crafting a malicious link or payload that a victim user is induced to click or load, resulting in script execution within the victim's session context and potential access to sensitive patient or administrative data.
