Samba: ad dc password exposure to privileged users and rodcs

A design flaw was found in Samba's DirSync control implementation, which exposes passwords and secrets in Active Directory to privileged users and Read-Only Domain Controllers (RODCs). This flaw allows RODCs and users possessing the GET_CHANGES right to access all attributes, including sensitive secrets and passwords. Even in a default setup, RODC DC accounts, which should only replicate some passwords, can gain access to all domain secrets, including the vital krbtgt, effectively eliminating the RODC / DC distinction. Furthermore, the vulnerability fails to account for error conditions (fail open), like out-of-memory situations, potentially granting access to secret attributes, even under low-privileged attacker influence.

Samba 安全漏洞

Samba是用于 Linux 和 Unix 的标准 Windows 互操作性程序套件。 Samba 4.19.1之前版本、4.18.8之前版本 和 4.17.12之前版本存在安全漏洞，该漏洞源于Samba AD DC 密码暴露给特权用户和 RODC，RODC 和具有 GET_CHANGES 的用户右键可以查看所有属性。
