Vulnerability from fkie_nvd - Published: 2026-03-09 09:15 - Updated: 2026-06-17 09:23
Severity
4.9 (Medium) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
Summary
An administrator may attempt to block all networks by specifying "\*" or "all" as the network identifier. However, these values are not supported and do not trigger any validation error. Instead, they are silently interpreted as network 0 which results in no networks being blocked at all.
