PRIOn knowledge basePRION:CVE-2017-11104Design/Logic Flaw
Knot DNS before 2.4.5 and 2.5.x before 2.5.2 contains a flaw within the TSIG protocol implementation that would allow an attacker with a valid key name and algorithm to bypass TSIG authentication if no additional ACL restrictions are set, because of an improper TSIG validity period check.
