Synopsis
The remote Samba server is potentially affected by multiple vulnerabilities.Description
The version of Samba running on the remote host is 4.0.x prior to 4.13.17, 4.14.x prior to 4.14.12, or 4.15.x prior to 4.15.5. It is, therefore, affected by multiple vulnerabilities:- Out-of-bounds heap read/write vulnerability in VFS module vfs_fruit allows code execution. (CVE-2021-44142)
- Information leak via symlinks of existence of files or directories outside of the exported share. (CVE-2021-44141)
- Samba AD users with permission to write to an account can impersonate arbitrary services. (CVE-2022-0336)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to Samba version 4.13.17, 4.14.12, or 4.15.5 or later.See Also
