Title
Anonymous FTP accounts must not have a functional shell. (Cat I impact)
Discussion
If an anonymous FTP account has been configured to use a functional shell, attackers could gain access to the shell if the account is compromised.
Check Content
Check the shell for the anonymous FTP account. Procedure: # grep "^ftp" /etc/passwd This is a finding if the seventh field is empty (the entry ends with a ':') or if the seventh field does not contain one of the following: /bin/false /dev/null /usr/bin/false /bin/true /sbin/nologin
Fix Text
Configure anonymous FTP accounts to use a non-functional shell. The Yast ‘Security and Users’ > ‘User and Group Management’ module can be used to configure the account. Or if necessary, edit the /etc/passwd file to remove any functioning shells associated with the ftp account and replace them with non-functioning shells, such as /bin/false.
