CVE-2021-22212 Detail
This vulnerability is currently awaiting analysis.
Description
ntpkeygen can generate keys that ntpd fails to parse. NTPsec 1.2.0 allows ntpkeygen to generate keys with ‘#’ characters. ntpd then either pads, shortens the key, or fails to load these keys entirely, depending on the key type and the placement of the ‘#’. This results in the administrator not being able to use the keys as expected or the keys are shorter than expected and easier to brute-force, possibly resulting in MITM attacks between ntp clients and ntp servers. For short AES128 keys, ntpd generates a warning that it is padding them.
