CVE-2025-46861
📋 TL;DR
Adobe Experience Manager versions 6.5.22 and earlier contain a stored Cross-Site Scripting vulnerability that allows low-privileged attackers to inject malicious JavaScript into form fields. When users visit pages containing the compromised fields, their browsers execute the attacker's code, potentially leading to session hijacking or data theft.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator sessions, compromise user accounts, deface websites, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Low-privileged attackers inject malicious scripts to steal session cookies or user credentials from other users accessing the affected pages.
If Mitigated
With proper input validation and output encoding, the impact is limited to minor data exposure or temporary service disruption.
🎯 Exploit Status
Requires authenticated low-privileged access. Exploitation involves injecting JavaScript into vulnerable form fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.5.23 or later
Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb25-48.html
Restart Required: Yes
Instructions:
1. Download Adobe Experience Manager 6.5.23 or later from Adobe's distribution portal. 2. Apply the service pack following Adobe's upgrade documentation. 3. Restart the AEM instance. 4. Verify the patch is applied correctly.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize user input in form fields
Configure AEM's XSS protection filters in /system/console/configMgr
Content Security Policy
allImplement strict CSP headers to restrict script execution
Add Content-Security-Policy headers via Apache/Dispatcher configuration
🧯 If You Can't Patch
- Restrict low-privileged user access to content creation/modification features
- Implement web application firewall rules to block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check AEM version via CRXDE Lite or system console. If version is 6.5.22 or earlier, the system is vulnerable.Check Version:
curl -u admin:password http://localhost:4502/system/console/status-productinfo.json | grep versionVerify Fix Applied:
After patching, verify version is 6.5.23 or later and test form fields for XSS by attempting to inject basic script payloads.📡 Detection & Monitoring
Log Indicators:
- Unusual content modifications by low-privileged users
- JavaScript payloads in request logs
- Multiple failed XSS attempts
Network Indicators:
- Unexpected script tags in HTTP responses
- Suspicious content in form submissions
SIEM Query:
source="aem-access.log" AND ("<script>" OR "javascript:" OR "onerror=" OR "onload=")
