CVE-2019-8088

9.8 CRITICAL

📋 TL;DR

CVE-2019-8088 is a command injection vulnerability in Adobe Experience Manager that allows attackers to execute arbitrary commands on affected systems. This affects AEM versions 6.2 through 6.5, potentially leading to complete system compromise. Organizations using these versions should prioritize patching.

💻 Affected Systems

Products:
  • Adobe Experience Manager
Versions: 6.2, 6.3, 6.4, 6.5
Operating Systems: All supported platforms (Windows, Linux, macOS)
Default Config Vulnerable: ⚠️ Yes
Notes: All standard installations of affected versions are vulnerable; no special configuration required

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with administrative access, data theft, lateral movement, and persistent backdoor installation

🟠

Likely Case

Unauthorized code execution leading to data exfiltration, service disruption, or ransomware deployment

🟢

If Mitigated

Limited impact due to network segmentation, minimal privileges, and proper monitoring

🌐 Internet-Facing: HIGH - AEM instances exposed to the internet are directly vulnerable to remote exploitation
🏢 Internal Only: MEDIUM - Internal instances still vulnerable to insider threats or compromised internal systems

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Command injection vulnerabilities typically have low exploitation complexity; public advisories increase weaponization likelihood

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Apply security updates specified in APSB19-48

Vendor Advisory: https://helpx.adobe.com/security/products/experience-manager/apsb19-48.html

Restart Required: Yes

Instructions:

1. Review APSB19-48 advisory 2. Download appropriate hotfix from Adobe Package Share 3. Install via AEM Package Manager 4. Restart AEM instance 5. Verify installation

🔧 Temporary Workarounds

Network Segmentation

all

Restrict network access to AEM instances to minimize attack surface

Input Validation Enhancement

all

Implement additional input validation for user-controlled parameters

🧯 If You Can't Patch

  • Isolate AEM instances in restricted network segments with firewall rules
  • Implement strict monitoring for command execution patterns and unusual process activity

🔍 How to Verify

Check if Vulnerable:

Check AEM version via CRXDE Lite or system console; versions 6.2-6.5 are vulnerable

Check Version:

curl -u admin:admin http://localhost:4502/system/console/status-productinfo.json | grep version

Verify Fix Applied:

Verify hotfix installation in Package Manager and confirm version is patched per APSB19-48

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution in logs
  • Suspicious process creation from AEM
  • Error logs showing command injection attempts

Network Indicators:

  • Unexpected outbound connections from AEM servers
  • Command and control traffic patterns

SIEM Query:

source="aem.log" AND ("command injection" OR "Runtime.exec" OR "ProcessBuilder")
