How the CVE Works:
CVE-2025-30149 is a reflected Cross-Site Scripting (XSS) vulnerability in OpenEMR’s AJAX script interface (super/layout_listitems_ajax.php). The flaw arises due to improper sanitization of the `target` parameter, allowing attackers to inject malicious JavaScript code. When a victim visits a crafted URL containing the payload, the script executes in their browser, potentially leading to session hijacking, data theft, or unauthorized actions within the EHR system. The vulnerability is mitigated in OpenEMR 7.0.3 by implementing proper input validation and output encoding.
DailyCVE Form:
Platform: OpenEMR
Version: <7.0.3
Vulnerability: Reflected XSS
Severity: Medium
Date: 04/30/2025
What Undercode Say:
Exploitation:
1. Craft a malicious URL:
http://target/openemr/super/layout_listitems_ajax.php?target=<script>alert(document.cookie)</script>
2. Social-engineer victims to click the link.
Detection:
curl -sk "http://target/openemr/super/layout_listitems_ajax.php?target=test" | grep -q "unsafe" && echo "Vulnerable"
Mitigation:
1. Upgrade to OpenEMR 7.0.3+.
2. Implement WAF rules to filter XSS payloads:
location ~ .php$ {
set $block_xss 0;
if ($args ~ "<script|javascript:|onload=") {
set $block_xss 1;
}
return 403 if $block_xss;
}
3. Manual patch for legacy versions:
// In layout_listitems_ajax.php $target = htmlspecialchars($_GET['target'], ENT_QUOTES, 'UTF-8');
Analytics:
- Attack Vector: Remote (Web)
- Privilege Escalation: Possible via session theft
- Exploitability: Low (requires user interaction)
- CVSS: 6.1 (Medium)
