CVE-2018-16889
This results in the leaking of encryption key information in log files via plaintext.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.54%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Ceph does not properly sanitize encryption keys in debug logging for v4 auth. This results in the leaking of encryption key information in log files via plaintext. Versions up to v13.2.4 are vulnerable.
