This flaw allows an attacker to… | ||
| CVE-2023-0922 | Med | 0.38 | 5.9 | 0.00 | Apr 3, 2023 | The Samba AD DC administration tool, when operating against a remote LDAP server, will by default send new or reset passwords over a signed-only connection. | ||
| CVE-2021-20251 | Med | 0.38 | 5.9 | 0.01 | Mar 6, 2023 | A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute force attacks being successful if special conditions are met. | ||
| CVE-2021-20316 | Med | 0.37 | 6.8 | 0.01 | Aug 23, 2022 | A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share. | ||
| CVE-2021-20254 | Med | 0.37 | 6.8 | 0.02 | May 5, 2021 | A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids).
