CGIWrap - Access Control Files

CGIWrap includes faclities similar to the cron facility for controlling who can access scripts. In general, I don't use this facility except to have a deny file available in those cases when I see someone abusing cgi scripts/extreme CPU utilization/obvious security hole/etc.

Note that none of the below is effective unless you have enabled access control files when you configure and install CGIWrap.

Access Control Logic

  • Neither file exists - Configuration Error
  • User in both files - Access Denied
  • Allow exists and user not in file - Access Denied
  • Deny exists and user in file - Access Denied
  • Otherwise - Access Allowed

Basically, in order for a user to be allowed to execute scripts through cgiwrap: If the allow file exists, the user has to be in it. If the deny file exists, the user can't be in it.

File Format

Without the host checking enabled, the format is just one userid per line. Same format as the cron allow and deny files.

With host checking enabled, it is (i think):


where x is the network and y is the mask. Userid can be * to match all users at that network/mask.
