How CVE-2025-46987 Works
CVE-2025-46987 is a stored Cross-Site Scripting (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 authenticated low-privileged attackers to inject malicious JavaScript payloads. When a victim accesses a compromised page, the script executes in their browser session, potentially leading to session hijacking, data theft, or unauthorized actions under the victim’s permissions. The attack persists server-side until manually purged, amplifying its impact.
DailyCVE Form
Platform: Adobe Experience Manager
Version: ≤ 6.5.22
Vulnerability: Stored XSS
Severity: Critical
Date: 06/13/2025
Prediction: Patch expected by 07/15/2025
What Undercode Say:
Exploitation Analysis
- Payload Injection: Attackers submit crafted JavaScript via form fields (e.g., comments, user profiles).
<script>alert(document.cookie)</script>
- Persistence: Malicious script saves to AEM’s content repository.
- Execution: Victims trigger payload when rendering the compromised page.
Mitigation Commands
1. Input Sanitization: Use AEM’s XSS API:
import com.adobe.granite.xss.XSSAPI; XSSAPI xss = sling.getService(XSSAPI.class); String sanitized = xss.filterHTML(userInput);
2. Disable Rich Text: For non-essential fields:
<fieldType>text</fieldType> <validation regex="^[a-zA-Z0-9\s]+$"/>
3. Patch Verification: Post-update, audit content nodes:
SELECT FROM [nt:base] WHERE CONTAINS(, '<script>');
Detection Script
import requests
aem_url = "https://target/aem/form"
payload = "<img src=x onerror=alert(1)>"
response = requests.post(aem_url, data={"field": payload}, auth=("user", "pass"))
if payload in response.text:
print("Vulnerable to CVE-2025-46987")
Post-Exploitation Checks
- Review AEM audit logs for suspicious entries:
grep -r "script" /var/aem/logs/error.log
- Quarantine compromised nodes via CRXDE Lite.
Temporary Workaround
Deploy a reverse proxy filter to strip script tags:
location /aem {
sub_filter '<script>' '';
sub_filter_once off;
}
Expected Patch Actions
Adobe will likely enforce stricter input validation in the XSSAPI service and update the Granite UI framework. Monitor `security.adobe.com` for APSB25-XX.
