CVE-2021-22212 describes a vulnerability in NTPsec 1.2.0 where the ntpkeygen utility can generate keys containing '#' characters, which ntpd then fails to parse correctly, leading to key truncation, padding, or complete failure to load. This issue primarily affects NTPsec and Fedora distributions utilizing it. The vulnerability is rated High (CVSS 7.4) due to its potential for Man-in-the-Middle (MITM) attacks, as shortened keys are easier to brute-force, with a network attack vector and high impact on confidentiality and integrity. There is currently no public exploit code available, nor is there evidence of active exploitation or significant community discussion surrounding this CVE.
