How CVE-2025-46873 Works
CVE-2025-46873 is a stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager (AEM) versions 6.5.22 and earlier. Attackers with low privileges can inject malicious JavaScript into vulnerable form fields, which persists in the database. 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 sanitization in form submissions, allowing arbitrary script embedding.
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 Analysis
1. Payload Injection:
<script>alert(document.cookie)</script>
Inserted into unprotected form fields (e.g., comments, user profiles).
2. Persistence:
Malicious scripts save to AEM’s JCR repository, executing on page load.
3. Impact:
Steal cookies, redirect users, or escalate privileges via CSRF.
Protection Commands
1. Input Sanitization:
FilterUtils.sanitize(userInput); // Use Adobe XSS Filter
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. Workaround:
Disable risky form components via AEM Console:
curl -u admin:password -X POST http://localhost:4502/system/console/configMgr/com.adobe.granite.csrf.impl.CSRFFilter
Detection Script
import requests
def check_xss(url):
payload = "<script>confirm(1)</script>"
r = requests.post(url, data={"field": payload})
return payload in r.text
Mitigation Steps
1. Upgrade to AEM 6.5.23+.
2. Audit custom forms for unsanitized outputs.
3. Enable Strict XSS filters in OSGi configs.
