CVE-2025-70045
📋 TL;DR
This vulnerability allows man-in-the-middle attacks by disabling TLS/SSL certificate validation in jxcore jxm master. When 'jx_obj.IsSecure' is true, the application sets 'rejectUnauthorized': false in HTTPS requests, making encrypted connections vulnerable to interception. This affects all users of vulnerable jxcore jxm master installations.
💻 Affected Systems
- jxcore jxm master
📦 What is this software?
Jxm by Jxcore
⚠️ Risk & Real-World Impact
Worst Case
Attackers can intercept, decrypt, and modify all HTTPS traffic between the application and external services, potentially stealing sensitive data, credentials, or injecting malicious content.
Likely Case
Man-in-the-middle attackers can eavesdrop on encrypted communications and potentially steal authentication tokens, API keys, or other sensitive information transmitted over HTTPS.
If Mitigated
With proper network segmentation and monitoring, impact is limited to potential data leakage from the specific vulnerable application component.
🎯 Exploit Status
The vulnerability is simple to exploit with man-in-the-middle positioning. The GitHub gist provides technical details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://github.com/jxcore/jxm
Restart Required: Yes
Instructions:
1. Monitor jxcore/jxm GitHub repository for security updates. 2. Apply patch when available. 3. Restart affected services.
🔧 Temporary Workarounds
Code modification to enforce certificate validation
allManually modify the application code to remove or override the 'rejectUnauthorized': false setting
# Requires code review and modification of jxcore jxm master source code
Network-level certificate validation
allImplement SSL/TLS inspection at network perimeter to enforce certificate validation
# Configure firewall/proxy with SSL inspection and certificate validation
🧯 If You Can't Patch
- Isolate vulnerable systems in restricted network segments with no internet access
- Monitor all outbound HTTPS traffic from affected systems for anomalies
🔍 How to Verify
Check if Vulnerable:
Review application code for 'rejectUnauthorized': false in HTTPS request options when 'jx_obj.IsSecure' is true
Check Version:
# Check jxcore version: jx --version
Verify Fix Applied:
Verify code no longer contains 'rejectUnauthorized': false or it's set to true in all HTTPS configurations
📡 Detection & Monitoring
Log Indicators:
- HTTPS connection failures due to certificate validation
- Unusual outbound HTTPS connections
Network Indicators:
- HTTPS traffic to unexpected destinations
- SSL/TLS handshakes without proper certificate validation
