CVE-2006-6264
Teredo creates trusted peer entries for arbitrary incoming source Teredo addresses, even if the low 32 bits represent an intranet address, which might allow remote attackers to send IPv4 traffic to intranet hosts that use non-RFC1918 addresses,…
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 14.3%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
