CVE-2022-3592
A symlink following vulnerability was found in Samba, where a user can create a symbolic link that will make 'smbd' escape the configured share path.
Does this matter?
Lower severity and a low EPSS score (2.45%). Track it; it rarely justifies an emergency change on its own.
Description
A symlink following vulnerability was found in Samba, where a user can create a symbolic link that will make 'smbd' escape the configured share path. This flaw allows a remote user with access to the exported part of the file system under a share via SMB1 unix extensions or NFS to create symlinks to files outside the 'smbd' configured share path and gain access to another restricted server's filesystem.
