An issue was discovered in Illumos in Nexenta NexentaStor 4.0.5 and 5.1.2, and other products. The SMB server allows an attacker to have unintended access, e.g., an attacker with WRITE_XATTR can change permissions. This occurs because of a combination of three factors: ZFS extended attributes are used to implement NT named streams, the SMB protocol requires implementations to have open handle semantics similar to those of NTFS, and the SMB server passes along certain attribute requests to the underlying object (i.e., they are not considered to be requests that pertain to the named stream).

The weakness was shared 12/27/2022 as 10506. The advisory is shared for download at illumos.org. This vulnerability was named CVE-2019-9579 since 03/05/2019. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1222.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
