CVE-2024-50837
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability exists in the KASHIPARA E-learning Management System Project 1.0 admin interface. Attackers can inject malicious scripts via firstname and username parameters, which execute when administrators view user lists. This affects all installations of version 1.0 with admin access.
💻 Affected Systems
- KASHIPARA E-learning Management System Project
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal admin session cookies, gain full system control, deface the platform, or install backdoors for persistent access.
Likely Case
Session hijacking leading to unauthorized admin access, data theft, or privilege escalation within the learning management system.
If Mitigated
Limited impact if proper input validation and output encoding are implemented, though stored XSS remains dangerous.
🎯 Exploit Status
Exploitation requires admin privileges to inject payloads, but public proof-of-concept exists in GitHub repository.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None known
Restart Required: No
Instructions:
No official patch available. Implement input validation and output encoding in /admin/admin_user.php for firstname and username parameters.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to sanitize firstname and username inputs in admin_user.php
Edit /admin/admin_user.php to add: htmlspecialchars($input, ENT_QUOTES, 'UTF-8') for firstname and username parameters
Content Security Policy
allImplement CSP headers to restrict script execution
Add header: Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Restrict admin access to trusted IP addresses only
- Implement web application firewall (WAF) rules to block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Test by entering <script>alert('XSS')</script> in firstname/username fields in admin interface and check if script executes when viewing user list.Check Version:
Check system version in admin panel or configuration filesVerify Fix Applied:
Attempt same XSS payload and verify it's properly encoded/escaped in output.📡 Detection & Monitoring
Log Indicators:
- Unusual script tags in firstname/username fields in admin logs
- Multiple failed login attempts followed by admin user creation
Network Indicators:
- HTTP requests with script payloads in POST parameters to admin_user.php
SIEM Query:
source="web_logs" AND (uri="/admin/admin_user.php" AND (param="firstname" OR param="username") AND payload="<script>"
