CVE-2022-32743Network attack vector

Unauthorized dNSHostName modification via missing right validation

Published Sep 1, 2022 · Updated Aug 3, 2024

Improper authorization in Samba 4.1.0 through 4.16.6 allows remote attackers to alter computer dNSHostName values through LDAP. The Active Directory DC LDAP modify path grants the Validated-DNS-Host-Name right without checking that a proposed value matches the computer name and domain. Any otherwise unprivileged domain user able to modify a computer object can corrupt that directory attribute; no confidentiality or availability impact is reported.
