Description
All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed.
A vulnerability was found in Samba due to an insecure link following. By querying a symlink inside the exported share using SMB1 with unix extensions turned on, an attacker can discover if a named or directory exists on the filesystem outside the exported share. This flaw allows a remote authenticated attacker to obtain sensitive information.
