CVE-2024-46639
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability in HelpDeskZ v2.0.2 allows attackers to inject malicious scripts into the Custom Fields Name text field. When users view tickets containing the crafted payload, the scripts execute in their browser context. This affects all HelpDeskZ v2.0.2 installations with custom fields enabled.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, perform account takeover, deface the helpdesk interface, or redirect users to malicious sites, potentially compromising the entire helpdesk system and user data.
Likely Case
Attackers inject malicious scripts that steal user session cookies or credentials when users view affected tickets, leading to unauthorized access to helpdesk accounts.
If Mitigated
With proper input validation and output encoding, the payload would be rendered harmless as plain text rather than executable code.
🎯 Exploit Status
Exploit requires attacker to have access to create or modify tickets with custom fields. Public proof-of-concept demonstrates simple script injection.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check for official patch from HelpDeskZ developers. 2. If patch is released, download and apply according to vendor instructions. 3. Verify fix by testing custom field input sanitization.
🔧 Temporary Workarounds
Disable Custom Fields
allTemporarily disable the custom fields feature to prevent exploitation until a patch is available.
Edit HelpDeskZ configuration to disable custom fields functionality
Input Validation Filter
allImplement server-side input validation to sanitize HTML/script tags in custom field names.
Modify HelpDeskZ source code to add input sanitization for custom field inputs
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block XSS payloads in custom field inputs
- Restrict access to helpdesk interface to trusted users only and monitor for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Test by entering a simple XSS payload like <script>alert('test')</script> in the Custom Fields Name field and checking if it executes when viewing a ticket.Check Version:
Check HelpDeskZ version in admin panel or configuration filesVerify Fix Applied:
After applying fixes, test the same XSS payload to ensure it's properly sanitized and doesn't execute.📡 Detection & Monitoring
