📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise with attacker gaining the same privileges as the logged-in user, potentially leading to data theft, ransomware deployment, or lateral movement.

🟠

Likely Case

Local privilege escalation leading to malware installation, data exfiltration, or persistence mechanisms being established on the compromised system.

🟢

If Mitigated

Limited impact due to application sandboxing or restricted user privileges, potentially resulting in application crash rather than full compromise.

🌐 Internet-Facing: LOW
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Exploitation requires user interaction (opening malicious file). No public exploit code available at this time.

🔧 Temporary Workarounds

Restrict InDesign file handling

all

Configure system to open .indd files with alternative applications or require verification before opening

Application sandboxing

all

Run InDesign in restricted mode or sandboxed environment

🧯 If You Can't Patch

  • Implement application whitelisting to prevent execution of unauthorized code
  • Restrict user privileges to standard user accounts (not administrator)

🔍 How to Verify

Check if Vulnerable:

Check InDesign version via Help > About InDesign menu. If version is 20.4 or earlier, or 19.5.4 or earlier, system is vulnerable.

Check Version:

On Windows: wmic product where name="Adobe InDesign" get version
On macOS: /Applications/Adobe\ InDesign\ */Adobe\ InDesign.app/Contents/Info.plist | grep -A1 CFBundleShortVersionString

Verify Fix Applied:

Verify version is 20.5 or later, or 19.5.5 or later after applying update.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected InDesign crashes with memory access violations
  • Suspicious file opens from untrusted sources
  • Unusual child processes spawned from InDesign

Network Indicators:

  • Outbound connections from InDesign process to unknown IPs
  • DNS requests for suspicious domains following file open

SIEM Query:

process_name:"InDesign.exe" AND (event_id:1000 OR event_id:1001) AND exception_code:0xc0000005
