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.

  • MBS UBR-01 Mk II 6.0.1.0

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
