VULNERABILITY SUMMARY:
A potential vulnerability has been identified with HP-UX running ObAM 5.0 with the 
WebAdmin capability enabled.  This vulnerability could be exploited remotely to allow 
unauthorized access.
SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.
HP-UX B.11.11 running ObAM 5.0
BACKGROUND:
The version of the Apache web server delivered with ObAM 5.0 has potential security 
vulnerabilities.  The Apache web server is used to implement the WebAdmin feature, which 
is disabled by default.  The WebAdmin feature is used by  Service Control Manager 1.0 and 
by Partition Manager 1.0.

     AFFECTED VERSIONS

      Note: To determine if a system has an affected version,
            search the output of "swlist -a revision -l fileset"
            for an affected fileset.  Then determine if the
            recommended patch or update is installed.


      HP-UX B.11.11
      =============
      OBAM.OBAM-WEB
      action:  disable the OBAM web administration interface

      END AFFECTED VERSIONS
RESOLUTION:
Check the /etc/rc.config.d/webadmin file.   If  the default  value ("WEBADMIN= 0" ) has 
been changed,  edit the file to set "WEBADMIN=0",  and run the following run the following 
as root to stop the Apache server if it had been running:

       /usr/obam/server/bin/apachectl stop


The steps above will disable the WebAdmin feature.   Service Control Manager 1.0  and 
Partition Manager 1.0 must then be  executed  locally  and displayed to an X11 server to 
provide remote administration.  HP Systems Insight Manager can installed and used instead 
of Service Control Manager to provide remote administration via a web browser.
