CVE-2017-11104 (GCVE-0-2017-11104)

Vulnerability from cvelistv5 – Published: 2017-07-08 10:00 – Updated: 2024-08-05 17:57

Summary

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.

Severity ?

No CVSS data available.
