Network Director: Use of Hard-coded Cryptographic Key
CVE-2025-44963 is a high-severity use of hard-coded cryptographic key vulnerability in Network Director from RUCKUS, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 4.5 as the first without the flaw, so updating Network Director to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.64% chance of exploitation within 30 days, higher than 51% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Network Director to 4.5 or a later version.
- Update Ruckus Network Director to 4.5.0.0 or a later version.
- Read the advisory on webresources.commscope.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
