CVE-2024-48623
📋 TL;DR
This vulnerability allows attackers to inject malicious scripts via the list_id and domain_id parameters in queue/index.php of DomainMOD. When exploited, it enables reflected cross-site scripting attacks that can steal session cookies, redirect users, or perform actions on their behalf. All DomainMOD installations below version 4.12.0 are affected.
💻 Affected Systems
- DomainMOD
📦 What is this software?
Domainmod by Domainmod
⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator session cookies, gain full administrative access to DomainMOD, and potentially compromise the entire domain management system and associated domains.
Likely Case
Attackers steal user session cookies to impersonate legitimate users, modify domain records, or redirect users to malicious sites.
If Mitigated
With proper input validation and output encoding, the attack fails to execute malicious scripts, limiting impact to parameter manipulation only.
🎯 Exploit Status
The vulnerability is in a GET request parameter, making it trivial to craft malicious URLs. Public proof-of-concept is available in the GitHub issue.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.12.0
Vendor Advisory: https://github.com/domainmod/domainmod/issues/176
Restart Required: No
Instructions:
1. Backup your current DomainMOD installation. 2. Download DomainMOD v4.12.0 or later from the official repository. 3. Replace the vulnerable queue/index.php file with the patched version. 4. Verify the fix by testing the affected parameters.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize list_id and domain_id parameters before processing
# In queue/index.php, add: $list_id = filter_var($_GET['list_id'], FILTER_SANITIZE_STRING);
# $domain_id = filter_var($_GET['domain_id'], FILTER_SANITIZE_STRING);
Web Application Firewall Rule
linuxBlock requests containing script tags or JavaScript in the list_id and domain_id parameters
# ModSecurity rule: SecRule ARGS_GET:"(list_id|domain_id)" "@rx <script" "id:1001,phase:2,deny,status:403,msg:'XSS attempt detected'"
🧯 If You Can't Patch
- Implement a Web Application Firewall (WAF) with XSS protection rules
- Disable public access to the DomainMOD interface and restrict to internal network only
🔍 How to Verify
Check if Vulnerable:
Test by accessing queue/index.php?list_id=<script>alert('XSS')</script> and checking if script executesCheck Version:
Check DomainMOD version in admin interface or review CHANGELOG.md fileVerify Fix Applied:
After patching, test the same payload and confirm script does not execute📡 Detection & Monitoring
Log Indicators:
- GET requests to queue/index.php with script tags or JavaScript in parameters
- Unusual parameter values containing <, >, or script patterns
Network Indicators:
- HTTP requests with suspicious parameters to the vulnerable endpoint
- URLs containing encoded script tags or JavaScript
SIEM Query:
source="web_logs" AND uri_path="/queue/index.php" AND (query_string="*<script*" OR query_string="*javascript:*")
