CVE-2025-44955
📋 TL;DR
CVE-2025-44955 is a privilege escalation vulnerability in RUCKUS Network Director (RND) where jailed users can gain root access using a weak, hardcoded password. This affects organizations using RND for network management, allowing attackers with limited access to gain complete control of affected systems.
💻 Affected Systems
- RUCKUS Network Director (RND)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full root access to the RND system, allowing them to compromise the entire network infrastructure, steal sensitive data, deploy ransomware, or pivot to other systems.
Likely Case
Malicious insiders or attackers who gain initial access escalate privileges to root, enabling them to modify network configurations, intercept traffic, or install persistent backdoors.
If Mitigated
With proper network segmentation and access controls, impact is limited to the RND system itself, though root compromise still allows significant damage within that environment.
🎯 Exploit Status
Exploitation requires initial access as a jailed user, but the hardcoded password makes privilege escalation trivial once that access is obtained.
🛠️ 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 official RUCKUS support portal. 2. Backup current configuration. 3. Apply the update following RUCKUS upgrade procedures. 4. Restart the RND system to complete installation.
🔧 Temporary Workarounds
Disable or restrict jailed user accounts
linuxRemove or disable access for jailed user accounts to prevent exploitation
# Check for jailed users: getent passwd | grep -i jail
# Disable specific user: usermod -L <username>
# Remove user from system: userdel <username>
Network segmentation and access controls
allIsolate RND management interface from untrusted networks and restrict access to authorized administrators only
🧯 If You Can't Patch
- Isolate RND system on a dedicated management VLAN with strict firewall rules
- Implement multi-factor authentication and monitor for suspicious privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check RND version via web interface or CLI. Versions before 4.5 are vulnerable. Also check for existence of jailed user accounts.Check Version:
# From RND CLI: show version | include DirectorVerify Fix Applied:
Verify RND version is 4.5 or later and test that jailed users cannot escalate to root using known hardcoded credentials.📡 Detection & Monitoring
Log Indicators:
- Failed or successful authentication attempts using hardcoded credentials
- Privilege escalation events from jailed users to root
- Unusual root-level commands from previously jailed user accounts
Network Indicators:
- Unexpected SSH or administrative connections to RND system
- Traffic patterns indicating privilege escalation attempts
SIEM Query:
