DescriptionGitHub Advisory

OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 8.0.0.3 contais a SQL injection vulnerability in the ajax_save CAMOS form that can be exploited by authenticated attackers. The vulnerability exists due to insufficient input validation in the ajax_save page in the CAMOS form. Version 8.0.0.3 patches the issue.

AnalysisAI

SQL injection in OpenEMR versions prior to 8.0.0.3 enables authenticated attackers to execute arbitrary SQL commands through the CAMOS form's ajax_save functionality, potentially leading to complete database compromise including extraction of sensitive health records, data modification, and service disruption. The vulnerability requires low-privilege authentication (PR:L) with no user interaction (UI:N) and is network-exploitable (AV:N), though EPSS assigns only 0.03% (8th percentile) exploitation probability and no public exploit identified at time of analysis. …

Vulnerability AssessmentAI

Exploitation Requires authenticated user account in OpenEMR versions prior to 8.0.0.3. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS v3.1 score of 8.8 (High) reflects significant technical impact with network attack vector (AV:N), low complexity (AC:L), and high impact to confidentiality, integrity, and availability (C:H/I:H/A:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated attacker with low-privilege credentials (such as a standard clinical user account) accesses the OpenEMR CAMOS form interface and intercepts the ajax_save request. By injecting malicious SQL syntax into vulnerable form parameters, the attacker executes arbitrary database queries to extract the entire patient database containing protected health information (PHI), modify medical records to alter treatment documentation, or delete critical data causing service disruption. …
Remediation Upgrade OpenEMR to version 8.0.0.3 or later, which contains the fix for this SQL injection vulnerability as documented in the release notes at https://github.com/openemr/openemr/releases/tag/v8_0_0_3. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: inventory all OpenEMR instances and confirm running versions; identify systems below 8.0.0.3 and restrict CAMOS form access to administrative users only pending patching. …
