CVE-2022-2031

Published: 27 July 2022

Samba AD users can bypass certain restrictions associated with changing passwords

Notes

AuthorNote

Fixing this in Ubuntu 18.04 LTS would require substantial
code backports. We will not be fixing this issue in Ubuntu 18.04
LTS. In environments where this is of concern, we recommend
updating to a more recent Ubuntu version, or disabling kpasswd
if this is not passible.

Mitigation

kpasswd is not a critical protocol for the AD DC in most installations, it
can be disabled by setting "kpasswd port = 0" in the smb.conf.
