CVE-2024-28825
Improper restriction of excessive authentication attempts on some authentication methods in Checkmk before 2.3.0b5 (beta), 2.2.0p26, 2.1.0p43, and in Checkmk 2.0.0 (EOL) facilitates password brute-forcing.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
