DNSSEC NSEC Records

The remote DNSSEC server uses NSEC records for negative answers to queries for its zones. NSEC records link to additional existing domains. These existing domains can be used to craft further queries that will lead to further NSEC records and thus further domains. This process can be repeated unt...

tls-nextprotoneg NSE Script

Enumerates a TLS server's supported protocols by using the next protocol negotiation extension. This works by adding the next protocol negotiation extension in the client hello packet and parsing the returned server hello's NPN extension data. For more information, see: Script Arguments...

DEBIAN-CVE-2011-4869

validator/valnsec3.c in Unbound before 1.4.13p2 does not properly perform proof processing for NSEC3-signed zones, which allows remote DNS servers to cause a denial of service daemon crash via a malformed response that lacks expected NSEC3 records, a different vulnerability than CVE-2011-4528...

dns-nsec-enum NSE Script

Enumerates DNS names using the DNSSEC NSEC-walking technique. Output is arranged by domain. Within a domain, subzones are shown with increased indentation. The NSEC response record in DNSSEC is used to give negative answers to queries, but it has the side effect of allowing enumeration of all...

CVE-2010-0097

CVE-2010-0097 affects ISC BIND 9.x where DNSSEC validation of NSEC/NSEC3 records is flawed, enabling remote attackers to add the AD flag to forged NXDOMAIN responses for an existing domain. Public advisories confirm fixes in later BIND releases (upstream: 9.6-ESV-R1 and 9.7.0.dfsg) and point to u...
