fix

The ignore_dot variable in uroot determines whether the shell to accepts or denies a "." in the path of an assumed process.

Vulnerability:

By having a dot in the path, it is possible to inadvertently allow an unprivileged user to gain access to host resources. If "." is in the path, there is a possibility that a malicious script could be picked up first and execute several Unix commands giving users undesired access.

Turning ignore_dot on solves this vulnerability.

Enabling ignore_dot feature for uroot:

  1. Using your favorite editor, load /etc/uroot.cfg
  2. Somewhere near the top of the file (preferrably after the lines that start with a #), type in this line:
  3. Defaults:ALL ignore_dot

  4. Save the file
