The remote Samba server, according to its version number, may be vulnerable 
to a remote file access vulnerability.  


This vulnerability allows an attacker to access arbitrary files which exist
outside of the shares's defined path.

An attacker needs a valid account to exploit this flaw.

Risk factor : High";
