HEWLETT-PACKARD SECURITY ADVISORY: #00078, 29 April 1998
-------------------------------------------------------------------------
The information in the following Security Advisory should be acted upon
as soon as possible. Hewlett-Packard Company will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Advisory as soon as possible.
-------------------------------------------------------------------------
PROBLEM: Insecure configuration of any version of OpenMail.
PLATFORM: Any HP 9000 series 700/800 systems running OpenMail.
DAMAGE: Users can run arbitrary shell commands.
SOLUTION: Reconfigure OpenMail per the OpenMail Technical Guide.
AVAILABILITY: N/A
-------------------------------------------------------------------------
I.
A. Background
Hewlett-Packard has learned of an OpenMail server misconfiguration that
can give users the ability to run arbitrary shell commands. This
applies to all currently supported OpenMail versions (B.05.01 (GR4)
and B.05.10 (GR5), as well as the earlier B.04.01 (GR3) revision.
B. Fixing the problem
Ref: [OpenMail Technical Guide, pages 3-366, and 3-369]
Hewlett-Packard notes that this issue has already been adequately
addressed in OpenMail. There is a general parameter setting
(UAL_PRINT_SERVER_ONLY) in the general.cfg file, that, if set to TRUE,
forces all server printing to go through OpenMail's print server.
The general customization file general.cfg is located in
/var/opt/openmail/sys, as is the print server's configuration file
print.cfg. On the client all that is necessary is to then change the
'Printer Server Command' to point to one of the configured printers.
OpenMail's print server uses a configuration file to configure available
printers, and validates each print request against its configured
printers. Any print requests that do not match the required syntax will
not be executed.
More information about OpenMail's print server and how to configure it
can be found in the OpenMail Technical Guide (pages 3-366 to 3-369 for
the GR5 edition)
