CVE-2022-23188

7.8 HIGH

📋 TL;DR

Adobe Illustrator versions 25.4.3 and earlier and 26.0.2 and earlier contain a buffer overflow vulnerability when processing malicious files. This could allow attackers to execute arbitrary code with the privileges of the current user. Exploitation requires the victim to open a specially crafted malicious file in Illustrator.

💻 Affected Systems

Products:
  • Adobe Illustrator
Versions: 25.4.3 and earlier, 26.0.2 and earlier
Operating Systems: Windows, macOS
Default Config Vulnerable: ⚠️ Yes
Notes: All default installations of affected versions are vulnerable when processing malicious files.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise via arbitrary code execution with user privileges, potentially leading to data theft, ransomware deployment, or lateral movement.

🟠

Likely Case

Local privilege escalation or malware installation on the affected workstation when a user opens a malicious file.

🟢

If Mitigated

Limited impact if user opens file in sandboxed environment or with restricted privileges.

🌐 Internet-Facing: LOW - Exploitation requires user interaction with a malicious file, not directly accessible via network.
🏢 Internal Only: MEDIUM - Risk exists if users open untrusted files from internal sources like email attachments or shared drives.

🎯 Exploit Status

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

Exploitation requires user interaction (opening malicious file) and knowledge of buffer overflow techniques.

🔍 How to Verify

Check if Vulnerable:

Check Illustrator version via Help > About Illustrator. If version is 25.4.3 or earlier, or 26.0.2 or earlier, system is vulnerable.

Check Version:

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

Verify Fix Applied:

Verify Illustrator version is 25.4.4 or later for version 25.x, or 26.0.3 or later for version 26.x.

📡 Detection & Monitoring

Log Indicators:

  • Illustrator crash logs with memory access violations
  • Unexpected Illustrator process spawning child processes

Network Indicators:

  • Illustrator process making unexpected outbound connections after file open

SIEM Query:

process_name:"Illustrator.exe" AND (event_id:1000 OR event_id:1001) OR parent_process:"Illustrator.exe" AND process_creation
