UBUNTU-CVE-2023-4154 (CVE-2023-4154)

Vulnerability from osv_ubuntu – Published: 2023-10-10 00:00 – Updated: 2026-04-22 07:45 – Source website

Details

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.

Summary

samba vulnerabilities

Details

Sri Nagasubramanian discovered that the Samba acl_xattr VFS module incorrectly handled read-only files. When Samba is configured to ignore system ACLs, a remote attacker could possibly use this issue to truncate read-only files. (CVE-2023-4091)

Andrew Bartlett discovered that Samba incorrectly handled the DirSync control. A remote attacker with an RODC DC account could possibly use this issue to obtain all domain secrets. (CVE-2023-4154)

Andrew Bartlett discovered that Samba incorrectly handled the rpcecho development server. A remote attacker could possibly use this issue to cause Samba to stop responding, resulting in a denial of service. (CVE-2023-42669)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
