How CVE-2025-46985 Works
Adobe Experience Manager (AEM) versions 6.5.22 and earlier fail to properly sanitize user-supplied input in form fields, allowing attackers with low privileges to inject malicious JavaScript. When a victim accesses a compromised page, the script executes in their browser, 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 payloads persist in the database and render unsanitized.
DailyCVE Form
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/13/2025
Prediction: Patch by 07/15/2025
What Undercode Say:
Exploitation
1. Payload Injection:
<script>alert(document.cookie)</script>
Inserted into vulnerable form fields (e.g., comments, user profiles).
2. Persistence:
Malicious scripts are stored in AEM’s JCR repository and served to all visitors.
3. Execution:
Triggers when victims load the infected page.
Protection
1. Input Sanitization:
// Use XSS filters in servlets import org.apache.commons.text.StringEscapeUtils; String sanitized = StringEscapeUtils.escapeHtml4(userInput);
2. CSP Headers:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
3. AEM-Specific Fix:
<!-- Disable risky features in /apps/<component>/dialog.xml --> <clientlibs js="disabled"/>
Detection
1. Scanning:
grep -r "eval(" /path/to/aem/instance
2. Log Analysis:
SELECT FROM crx_log WHERE message LIKE "%<script>%";
Patch Verification
1. Version Check:
curl -I http://aem-instance/libs/granite/core/content/login.html | grep X-Version
2. Exploit Test:
import requests
response = requests.post("http://target/form", data={"field": "<img src=x onerror=alert(1)>"})
assert "<script>" not in response.text
Mitigation Timeline
- Immediate: Apply WAF rules to block XSS patterns.
- Short-term: Disable vulnerable components.
- Long-term: Upgrade to patched version post-release.
