Executive Summary

[{'type': 'paragraph', 'content': 'CVE-2026-32127 is a high-severity SQL injection vulnerability found in OpenEMR versions prior to 8.0.0.1, specifically in the ajax graphs library.'}, {'type': 'paragraph', 'content': "The vulnerability occurs because the library directly inserts user-supplied input from the 'name' parameter into SQL queries without proper sanitization or escaping of special SQL characters."}, {'type': 'paragraph', 'content': 'Authenticated attackers can exploit this flaw by injecting arbitrary SQL code, which allows them to access or manipulate sensitive data in the database.'}, {'type': 'paragraph', 'content': 'Proof-of-concept exploits demonstrate techniques such as time-based and boolean-based SQL injection to extract sensitive information like usernames and hashed passwords.'}, {'type': 'paragraph', 'content': 'This vulnerability is fixed in OpenEMR version 8.0.0.1.'}] [1]

Impact Analysis

This vulnerability can lead to unauthorized access to sensitive medical and user data stored in OpenEMR.

Attackers can manipulate or extract confidential information such as usernames, hashed passwords, and potentially other protected health information.

The impact includes potential data breaches, loss of data integrity, and disruption of availability.

In some cases, exploitation may lead to server-side code execution and full database compromise.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by testing for SQL injection in the ajax graphs library of OpenEMR, specifically targeting the `name` parameter in POST requests to the file `library/ajax/graphs.php`.'}, {'type': 'paragraph', 'content': 'Proof-of-concept exploits use time-based and boolean-based SQL injection techniques. For example, injecting payloads like `date,SLEEP(5)` in the `name` parameter causes a delay, confirming the vulnerability.'}, {'type': 'paragraph', 'content': 'To detect the vulnerability, you can send authenticated POST requests to the vulnerable endpoint with crafted payloads in the `name` parameter and observe the response time or returned data.'}, {'type': 'list_item', 'content': 'Use curl or similar tools to send POST requests with payloads such as `name=date,SLEEP(5)` to observe time delays.'}, {'type': 'list_item', 'content': 'Example curl command: `curl -X POST -d "name=date,SLEEP(5)" -b cookies.txt https://<openemr-host>/library/ajax/graphs.php` (assuming you have authenticated cookies).'}, {'type': 'list_item', 'content': 'Monitor response times to detect time-based SQL injection.'}] [1]

Mitigation Strategies

The immediate mitigation step is to upgrade OpenEMR to version 8.0.0.1 or later, where this SQL injection vulnerability in the ajax graphs library has been fixed.

Until the upgrade can be performed, restrict authenticated user access to the vulnerable ajax graphs functionality to trusted users only.

Additionally, monitor logs for suspicious POST requests to `library/ajax/graphs.php` and consider implementing web application firewall (WAF) rules to detect and block SQL injection attempts targeting the `name` parameter.
