CVE-2022-1575
📋 TL;DR
CVE-2022-1575 is a critical vulnerability in draw.io diagramming software that allows attackers to bypass input sanitization and execute arbitrary code. In the desktop application, this leads to remote code execution, while in the web application it enables stored cross-site scripting attacks. All users of draw.io versions prior to 18.0.0 are affected.
💻 Affected Systems
- drawio (diagrams.net)
📦 What is this software?
Drawio by Diagrams
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through remote code execution, allowing attackers to install malware, steal data, or pivot to other systems.
Likely Case
Attackers execute malicious code on user systems through crafted diagrams, potentially leading to data theft, ransomware deployment, or credential harvesting.
If Mitigated
With proper network segmentation and endpoint protection, impact is limited to the compromised application instance.
🎯 Exploit Status
Exploitation requires users to open malicious diagram files. The vulnerability is well-documented in public repositories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 18.0.0 and later
Vendor Advisory: https://github.com/jgraph/drawio/commit/f768ed73875d5eca20110b9c1d72f2789cd1bab7
Restart Required: Yes
Instructions:
1. Download drawio version 18.0.0 or later from official sources. 2. Uninstall previous versions. 3. Install the updated version. 4. Restart the application.
🔧 Temporary Workarounds
Disable automatic diagram loading
allPrevent automatic loading of external diagram files
Network segmentation
allIsolate draw.io instances from critical systems
🧯 If You Can't Patch
- Implement strict file upload validation and scanning for diagram files
- Use application allowlisting to prevent unauthorized code execution
🔍 How to Verify
Check if Vulnerable:
Check drawio version in application settings or via 'drawio --version' commandCheck Version:
drawio --versionVerify Fix Applied:
Verify version is 18.0.0 or higher and test with known malicious diagram files📡 Detection & Monitoring
Log Indicators:
