Check: GEN005040
VMware ESX 3 Server:
GEN005040
(in version v1 r2)
Title
All FTP users must have a default umask of 077. (Cat II impact)
Discussion
The umask controls the default access mode assigned to newly created files. An umask of 077 limits new files to mode 700 or less permissive. Although umask is stored as a 4-digit number, the first digit representing special access modes is typically ignored or required to be 0.
Check Content
Check the umask setting for the FTP user. Procedure: # su - ftp $ umask If the umask value does not return 077, this is a finding.
Fix Text
Edit the initialization files for the FTP user and set the umask to 077.
