Summary

The LLTD Responder in Microsoft Windows Vista does not send the Mapper a response to a DISCOVERY packet if another host has sent a spoofed response first, which allows remote attackers to spoof arbitrary hosts via a network-based race condition, aka the "Total Spoof" attack.

Exploit prediction

9.94% chance of exploitation in the next 30 days, higher than 95% of all scored CVEs (FIRST EPSS, 2026-11-08).

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.
