CVE-2025-44963 Overview
CVE-2025-44963 is a hardcoded cryptographic key vulnerability [CWE-321] affecting RUCKUS Network Director (RND) versions before 4.5. The flaw allows a remote attacker who knows the hardcoded secret key to forge a JSON Web Token (JWT) and impersonate an administrator. Successful exploitation grants full administrative control over the network management platform, exposing managed RUCKUS infrastructure to configuration tampering, credential theft, and downstream attacks. CommScope published advisory ID 20250710 to address the issue. The vulnerability was coordinated through CERT/CC under Vulnerability Note VU#613753 and disclosed by Claroty's Team82 research group.
Critical Impact
Attackers who recover the embedded secret key can mint valid administrator JWTs without credentials, taking full control of RND and the network it manages.
Affected Products
- CommScope RUCKUS Network Director (RND) versions prior to 4.5
- Network deployments using RND for centralized RUCKUS device orchestration
- RUCKUS-managed wireless and switching infrastructure controlled through RND

Technical Details for CVE-2025-44963
Vulnerability Analysis
RUCKUS Network Director uses JSON Web Tokens to authenticate administrative sessions to its management interface. The application signs these tokens using a secret key embedded directly in the product distribution. Because the key is identical across deployments, anyone who extracts it from a single installation can sign tokens that any other RND instance will accept as valid.
An attacker who obtains the hardcoded key can construct a JWT containing an administrator identity claim and submit it to the RND API or web console. The server validates the signature against the shared secret and accepts the forged token. This bypasses password authentication, multi-factor controls, and session management entirely. The resulting administrator session permits configuration changes, credential extraction, firmware operations, and pivoting to managed access points and switches.
Root Cause
The root cause is the use of a hardcoded cryptographic key [CWE-321] for signing authentication tokens. Secure JWT implementations require per-instance secrets generated at install time or rotated from a key management service. Embedding a static secret in shipped code reduces the security of every deployment to the secrecy of the binary distribution.
Attack Vector
The attack is performed over the network against the RND management interface. The attacker needs no prior credentials and no user interaction. The high attack complexity rating reflects the prerequisite of recovering the hardcoded secret, which requires reverse engineering or access to the product files. Once the key is known, token forgery is trivial and repeatable against every vulnerable instance.
The vulnerability mechanism is described in the Claroty Team82 disclosure and the CERT/CC Vulnerability Note VU#613753. No public proof-of-concept exploit code has been released.
Detection Methods for CVE-2025-44963
Indicators of Compromise
- Administrator-level API calls or console logins from IP addresses not associated with known operator workstations
- JWT-authenticated sessions that lack a preceding interactive login event in audit logs
- Configuration changes, new local accounts, or firmware operations performed outside change-management windows
- Repeated requests to RND authentication endpoints with valid signatures but unusual iat or exp claim values
Detection Strategies
- Compare authentication audit trails against forwarded RND access logs to identify sessions that bypassed the login workflow
- Alert on administrator API usage from source networks that have never previously accessed the management plane
- Monitor for sudden privilege escalations or creation of new admin accounts on RND instances running versions before 4.5
Monitoring Recommendations
- Forward RND application, authentication, and audit logs to a central SIEM for correlation with network flow data
- Track outbound connections from managed RUCKUS devices to detect post-compromise lateral movement
- Enable alerting on changes to RND user accounts, role assignments, and integration credentials
How to Mitigate CVE-2025-44963
Immediate Actions Required
- Upgrade RUCKUS Network Director to version 4.5 or later, which replaces the hardcoded JWT signing key
- Restrict network access to the RND management interface to a dedicated administrative VLAN or jump host
- Rotate all administrator credentials and API tokens on RND and on managed devices after upgrading
- Review audit logs for unexpected administrative activity dating back to the deployment of any affected version
Patch Information
CommScope addressed CVE-2025-44963 in RUCKUS Network Director version 4.5. Customers should consult the CommScope Security Advisory FAQ for advisory ID 20250710 for upgrade packages and release notes. Verify the integrity of downloaded images against vendor-published hashes before deployment.
Workarounds
- Place RND behind a network firewall or reverse proxy that enforces source IP allowlisting for management traffic
- Require VPN or zero-trust network access before any administrator can reach the RND web console or API
- Disable or block external exposure of the RND management ports until the 4.5 upgrade is completed
