CVE-2025-44963
📋 TL;DR
CVE-2025-44963 allows attackers to forge administrator JSON Web Tokens (JWTs) in RUCKUS Network Director (RND) by exploiting a hardcoded secret key. This enables authentication bypass and administrative privilege escalation. Organizations running RND versions before 4.5 are affected.
💻 Affected Systems
- RUCKUS Network Director (RND)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the RUCKUS Network Director with administrative access, allowing attackers to reconfigure network infrastructure, deploy malicious firmware, intercept traffic, and pivot to other network segments.
Likely Case
Unauthorized administrative access to RND leading to network configuration changes, user account manipulation, and potential lateral movement within the network.
If Mitigated
Limited impact if network segmentation isolates RND management interfaces and strong access controls are in place, though authentication bypass remains possible.
🎯 Exploit Status
Exploitation requires knowledge of the hardcoded secret key, which may be obtained through reverse engineering or information disclosure. No authentication is required to exploit.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: RND 4.5 and later
Vendor Advisory: https://webresources.commscope.com/download/assets/FAQ+Security+Advisory%3A+ID+20250710/225f44ac3bd311f095821adcaa92e24e
Restart Required: Yes
Instructions:
1. Download RND version 4.5 or later from RUCKUS support portal. 2. Backup current configuration. 3. Apply the update through the RND web interface or CLI. 4. Restart the RND appliance/service. 5. Verify successful upgrade and functionality.
🔧 Temporary Workarounds
Network Segmentation
allIsolate RND management interface to trusted administrative networks only
Access Control Lists
allImplement strict firewall rules limiting access to RND management ports (typically 443/TCP)
🧯 If You Can't Patch
- Immediately restrict network access to RND management interface using firewall rules
- Implement multi-factor authentication for administrative access if supported
- Monitor RND logs for unauthorized access attempts and JWT-related anomalies
🔍 How to Verify
Check if Vulnerable:
Check RND version via web interface (Admin > System > About) or CLI command 'show version'. If version is below 4.5, system is vulnerable.Check Version:
show version (CLI) or check Admin > System > About in web interfaceVerify Fix Applied:
Verify RND version is 4.5 or higher. Test administrative JWT functionality by logging out and back in to ensure proper authentication.📡 Detection & Monitoring
Log Indicators:
- Failed login attempts followed by successful admin access
- JWT token generation/validation errors
- Unusual administrative actions from unexpected IP addresses
Network Indicators:
- HTTP/HTTPS requests to RND management interface with forged JWT tokens
- Authentication bypass patterns in web traffic
SIEM Query:
source="rnd-logs" AND (event_type="auth_failure" OR event_type="admin_action") | stats count by src_ip, user | where count > threshold
