How CVE-2025-46874 Works
CVE-2025-46874 is a reflected Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager (AEM) versions 6.5.22 and earlier. The flaw occurs due to improper input sanitization in web request parameters. When a maliciously crafted URL containing JavaScript payloads is processed by AEM, the server reflects the payload back in the HTTP response without proper encoding. An attacker can exploit this by tricking a victim into clicking a manipulated link, leading to arbitrary script execution in the victim’s browser session. This can result in session hijacking, unauthorized actions, or data theft.
DailyCVE Form
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Reflected XSS
Severity: Critical
Date: 06/13/2025
Prediction: Patch expected by 07/15/2025
What Undercode Say:
Exploitation Analysis
1. Crafting Malicious URL:
https://vulnerable-aem-instance/content/page.html?param=<script>alert(document.cookie)</script>
2. Social Engineering: Attacker sends the URL via phishing.
3. Execution: Victim’s browser processes the script in their session.
Protection Measures
1. Input Sanitization:
// Example Java filter for AEM
String sanitizedParam = ESAPI.encoder().encodeForHTML(request.getParameter("param"));
2. CSP Header:
Content-Security-Policy: default-src 'self'; script-src 'unsafe-inline' 'unsafe-eval'
3. WAF Rules:
location / {
modsecurity_rules 'SecRule ARGS "@detectXSS" "id:1001,deny,status:403"';
}
Detection Commands
1. CURL Test:
curl -v "https://target-aem/content/page.html?param=<script>alert(1)</script>"
2. Automated Scanning:
nuclei -t xss-detection.yaml -u https://target-aem
Patch Workaround
1. Disable Vulnerable Components:
<!-- Disable affected servlets in AEM --> <component status="disabled" />
2. Temporary Mitigation:
// Client-side sanitization (not foolproof) window.location.search.replace(/<script.?>.?<\/script>/gi, '');
Post-Exploit Actions
1. Session Invalidation:
Revoke all active sessions acltool --invalidate-all-sessions
2. Log Analysis:
grep "malicious_script" /var/log/aem/access.log
Expected Patch Fix
Adobe will likely enforce stricter input validation in the affected servlets and implement context-aware output encoding.
Note: Always test exploits in controlled environments. Unauthorized testing is illegal.
