N2w: Authentication Bypass by Spoofing
CVE-2025-59707 is a critical-severity authentication bypass by spoofing vulnerability in N2w from N2ws, with a CVSS 3.1 base score of 9.8 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 4.3.2 as the first without the flaw, so updating N2w to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.56% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update N2w to 4.3.2 or a later version.
- Read the advisory on n2ws.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.
