CVE-2022-1344
📋 TL;DR
This stored cross-site scripting (XSS) vulnerability in Organizr allows attackers to inject malicious scripts via filenames, which are then executed in users' browsers. It affects all users of Organizr versions prior to 2.1.1810. Successful exploitation can lead to session hijacking, data theft, and complete compromise of user accounts.
💻 Affected Systems
- Organizr
📦 What is this software?
Organizr by Organizr
⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator credentials, take full control of the Organizr instance, access all connected services, and pivot to internal network systems.
Likely Case
Attackers hijack user sessions, steal authentication tokens, access sensitive data within Organizr, and potentially compromise connected services.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before execution, preventing any client-side impact.
🎯 Exploit Status
Exploitation requires the ability to upload files with malicious filenames, which typically requires some level of access to the application.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.1.1810 and later
Vendor Advisory: https://github.com/causefx/organizr/commit/a09d834d995599756b62016af7026d2408ecf43a
Restart Required: Yes
Instructions:
1. Backup your Organizr configuration and data. 2. Update to version 2.1.1810 or later via the built-in updater or manual installation. 3. Restart the Organizr service. 4. Verify the update was successful by checking the version.
🔧 Temporary Workarounds
Input Validation Filter
allImplement a web application firewall or proxy that filters and sanitizes filename inputs before they reach Organizr.
Access Restriction
allRestrict file upload capabilities to trusted users only and implement strict filename validation rules.
🧯 If You Can't Patch
- Implement strict Content Security Policy (CSP) headers to prevent script execution from untrusted sources.
- Disable file upload functionality entirely or restrict it to administrators only.
🔍 How to Verify
Check if Vulnerable:
Check your Organizr version via the web interface settings page or by examining the application files. If version is below 2.1.1810, you are vulnerable.Check Version:
Check the Organizr web interface settings page or look for version information in the application's configuration files.Verify Fix Applied:
After updating, verify the version is 2.1.1810 or higher and test by attempting to upload a file with a filename containing script tags to confirm sanitization.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads with suspicious filenames containing script tags or JavaScript code
- Multiple failed upload attempts with malformed filenames
Network Indicators:
- HTTP requests with filenames containing script tags in parameters
- Unexpected JavaScript execution in browser sessions
