CVE-2024-43716

4.3 MEDIUM

📋 TL;DR

Adobe Experience Manager versions 6.5.21 and earlier have an improper access control vulnerability that allows low-privileged attackers to bypass security measures. This could lead to unauthorized access to restricted content or functionality. The vulnerability affects confidentiality with low impact and requires no user interaction for exploitation.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.5.21 and earlier
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: Affects both AEM Author and Publish instances. Requires attacker to have low-privilege access to the system.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Low-privileged user gains unauthorized access to sensitive content or administrative functions they shouldn't have access to, potentially leading to data exposure or privilege escalation.

🟠

Likely Case

Attacker bypasses security controls to access content or features beyond their assigned permissions, but within the constraints of their existing low-privilege account.

🟢

If Mitigated

Proper network segmentation and access controls limit the attacker's ability to reach vulnerable systems or sensitive data.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires low-privileged access but no user interaction. The vulnerability is in access control mechanisms.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 6.5.22 or later

Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb24-69.html

Restart Required: Yes

Instructions:

1. Download Adobe Experience Manager 6.5.22 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 update was successful.

🔧 Temporary Workarounds

Restrict low-privilege user access

all

Temporarily reduce permissions for low-privilege users to minimize attack surface

Use AEM User Administration console to review and restrict permissions

Network segmentation

all

Isolate AEM instances from untrusted networks and limit internal access

Configure firewall rules to restrict access to AEM ports (typically 4502, 4503)

🧯 If You Can't Patch

  • Implement strict access controls and principle of least privilege for all user accounts
  • Monitor AEM access logs for unusual activity from low-privilege accounts

🔍 How to Verify

Check if Vulnerable:

Check AEM version via the Welcome screen or system/console/status-productinfo endpoint

Check Version:

curl -u admin:password http://localhost:4502/system/console/status-productinfo | grep 'Adobe Experience Manager'

Verify Fix Applied:

Confirm version is 6.5.22 or later and test access control functionality

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized access attempts in AEM access logs
  • Low-privilege users accessing restricted paths or functions

Network Indicators:

  • Unusual request patterns to AEM endpoints from low-privilege accounts

SIEM Query:

source="aem-access.log" AND (event="ACCESS_DENIED" OR event="UNAUTHORIZED_ACCESS") AND user!="admin"
