CVE-2024-9571
📋 TL;DR
A Cross-Site Scripting (XSS) vulnerability in SOPlanning versions before 1.45 allows remote attackers to inject malicious scripts via the /soplanning/www/process/xajax_server.php endpoint. This could enable partial browser session takeover when an authenticated user views crafted content. Organizations using SOPlanning <1.45 are affected.

🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation for all parameters in xajax_server.php
# Requires code modification to validate/sanitize user input before processing
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block XSS payloads targeting the vulnerable endpoint
# WAF-specific configuration to block malicious scripts in requests to /soplanning/www/process/xajax_server.php
🧯 If You Can't Patch
- Implement strict Content Security Policy (CSP) headers to mitigate script execution
- Restrict access to SOPlanning application using network segmentation and authentication controls
🔍 How to Verify
Check if Vulnerable:
Check SOPlanning version in administration panel or by examining source files for version markers.Check Version:
Check SOPlanning admin interface or examine /soplanning/version.txt if presentVerify Fix Applied:
Confirm version is 1.45 or higher and test parameter inputs with basic XSS payloads (e.g., <script>alert('test')</script>) to ensure they are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /soplanning/www/process/xajax_server.php with script tags or JavaScript payloads
- Multiple failed authentication attempts followed by successful login and XSS payload delivery
Network Indicators:
- HTTP requests containing <script>, javascript:, or other XSS patterns targeting the vulnerable endpoint
