A vulnerability was found in Samba up to 4.9.14/4.10.9/4.11.1 (File Transfer Software). It has been classified as critical. This affects some unknown functionality of the component Client. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user.

The weakness was disclosed 11/06/2019 as not defined bug report (Bugzilla). The advisory is shared at bugzilla.redhat.com. This vulnerability is uniquely identified as CVE-2019-10218 since 03/27/2019. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available.
