CVE-2025-46870
📋 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 victims visit pages containing the compromised fields, their browsers execute the attacker's code. This affects organizations using vulnerable AEM installations.
💻 Affected Systems
- Adobe Experience Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or deploy additional malware through the compromised browser sessions.
Likely Case
Attackers with low privileges could hijack user sessions, deface content, or steal sensitive data from users who interact with the vulnerable form fields.
If Mitigated
With proper input validation and output encoding controls, the vulnerability would be prevented from executing malicious scripts even if injected.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access to inject scripts 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. Follow Adobe's upgrade documentation for your deployment type (AEM as a Cloud Service or on-premise). 3. Apply the update to all affected instances. 4. Restart AEM services after patching.
🔧 Temporary Workarounds
Input Validation and Output Encoding
allImplement strict input validation and output encoding for all user-controllable form fields to prevent script injection.
Content Security Policy
allImplement a strict Content Security Policy header to restrict script execution sources.
🧯 If You Can't Patch
- Restrict low-privileged user access to form editing capabilities
- Implement web application firewall rules to block XSS payload patterns
🔍 How to Verify
Check if Vulnerable:
Check AEM version via the Welcome screen or system console. Versions 6.5.22 and earlier are vulnerable.Check Version:
Navigate to AEM Welcome screen or use CRXDE Lite to check version information.Verify Fix Applied:
Confirm AEM 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 form submissions with script-like content
- Multiple failed login attempts followed by form edits
Network Indicators:
- HTTP requests containing script tags or JavaScript in form parameters
