📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through arbitrary code execution leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Malware installation or data exfiltration when users open malicious InDesign files from untrusted sources.
If Mitigated
Limited impact if proper file validation and user awareness prevent opening malicious files.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and heap manipulation knowledge. No public exploits known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: ID19.5.1 and later
Vendor Advisory: https://helpx.adobe.com/security/products/indesign/apsb24-88.html
Restart Required: Yes
Instructions:
1. Open Adobe Creative Cloud application. 2. Navigate to Updates section. 3. Install InDesign update to version 19.5.1 or later. 4. Restart InDesign after installation.
🔧 Temporary Workarounds
Disable InDesign file opening
windowsTemporarily disable InDesign file associations to prevent automatic opening of malicious files.
Use file validation
allImplement file validation policies to block suspicious InDesign files at email gateways and network perimeters.
🧯 If You Can't Patch
- Implement application whitelisting to restrict InDesign execution to trusted locations only.
- Enforce user awareness training about opening files from untrusted sources and implement file scanning for all InDesign files.
