VUL-0: CVE-2023-34968: samba: Spotlight server-side Share Path Disclosure
Last modified: 2024-06-12 07:32:16 UTC
=========================================================== == Subject: Spotlight server-side Share Path Disclosure == == CVE ID#: CVE-2023-34968 == == Versions: All versions of Samba prior to 4.18.5, 4.17.10 and 4.16.11. == == Summary: As part of the Spotlight protocol Samba == discloses the server-side absolute path of == shares and files and directories in search == results. =========================================================== =========== Description =========== As part of the Spotlight protocol, the initial request returns a path associated with the sharename targeted by the RPC request. Samba returns the real server-side share path at this point, as well as returning the absolute server-side path of results in search queries by clients. Known server side paths could be used to mount subsequent more serious security attacks or could disclose confidential information that is part of the path. To mitigate the issue, Samba will replace the real server-side path with a fake path constructed from the sharename. Important change in mdscli RPC library and mdsearch command ----------------------------------------------------------- As the absolute paths starting with the sharename prefix are not usable on the client side, the mdscli RPC library and hence the mdsearch command will from now on report paths of search results as relative paths relative to the root of the SMB share. Given a share [spotlight] path = /foo/bar spotlight = yes and a file inside this share with a full server-side path of /foo/bar/dir/file previously a search that matched this file would return the absolute server-side path of the file /foo/bar/dir/file which is now changed to dir/file by this patchset. ================== Patch Availability ================== Patches addressing both these issues have been posted to: https://www.samba.org/samba/security/ Additionally, Samba 4.18.5, 4.17.10 and 4.16.11 have been issued as security releases to correct the defect. Samba administrators are advised to upgrade to these releases or apply the patch as soon as possible. ================== CVSSv3 calculation ================== CVSS 3.0: AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N (5.3) ========== Workaround ========== As a possible workaround disable Spotlight by removing all configuration stanzas that enable Spotlight ("spotlight = yes|true"). ======= Credits ======= Originally reported by Ralph Boehme and Stefan Metzmacher of SerNet and the Samba team.
