Critical Path inJoin Directory Server 'iCon' Web Administration Interface Discloses Files on the System to Authenticated Remote Users
SecurityTracker Alert ID:  1004275
SecurityTracker URL:  http://securitytracker.com/id/1004275
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  May 10 2002
Impact:   Disclosure of system information, Disclosure of user information
Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 4.0
Description:   A file disclosure vulnerability was reported in Critical Path's inJoin directory server. An authenticated remote user can view files on the system that are readable by the directory server process.

Nomad Mobile Research Centre reported a directory traversal flaw in the 'iCon' web-based administrator interface of the inJoin Directory Server. A remote user with a valid username and password can read any file that is readable by the 'ids' user account.

An authenticated remote user can connect to the iCon port (tcp 1500) and present a modified version of a URL intended to be used to view log entries. The normal format is:

http://ip:1500/CONF&LOG=iCon.err&NOIH=no&FRAMES=y

According to the report, the "LOG=" parameter, which is typically set to 'iCon.err', is not analyzed by the system. An authenticated remote user can replace this with an absolute path for another filename to view the contents of the target file. A demonstration exploit URL is provided:

http://ip:1500/CONF&LOG=/etc/passwd&NOIH=no&FRAMES=y

The administrative interface reportedly runs under the 'ids' account, so only files that are readable by the 'ids' user account can be viewed using this method.

Impact:   An authenticate remote user can view files on the system that are readable by the 'ids' user account.
Solution:   No solution was available at the time of this entry. However, the vendor is reportedly preparing a maintenance release (iCon 4.1.4.7) that, when available, will be posted to the Critical Path support website:

http://support.cp.net

The web site is available to supported customers. The release is apparently planned for the "next few weeks."

Cause:   Access control error, Input validation error

Per our policy at http://www.nmrc.org/advise/policy.txt, we are releasing
these advisories as these are not high priority and the vendor has a fix
that is scheduled to be released soon.  In an effort to save bandwidth,
both advisories are in this single email.  NMRC will see you at DefCon in
Las Vegas!

         Platforms  : Solaris 2.8
         Application: Critical Path inJoin V4.0 Directory Server
         Severity   : Medium

Synopsis
--------

This advisory documents a web traversal vulnerability in the Web-based
administrator interface, named iCon, of the inJoin Directory Server that
allows an attacker with the correct username and password to read any file
accessible to the ids user.


Details
-------

The administrative web server, iCon, listens on TCP port 1500 and runs
under the ids account. By connecting to this port using a web browser and
entering a correct administrator username and password, an operator can
remotely administer the Directory Server and view log entries. The URL
used to view log entries is of the form.


  http://ip:1500/CONF&LOG=iCon.err&NOIH=no&FRAMES=y


The value of the file= parameter refers to a file named iCon.err.
Unfortunately, no checks are performed on the location of this value.
Therefore, an authenticated user can replace the file= parameter with the
absolute path to a filename and read the contents. For example, the
following request returns the /etc/passwd file,


  http://ip:1500/CONF&LOG=/etc/passwd&NOIH=no&FRAMES=y


Only those files that can be read by the ids account are accessible. For
example, by default, /etc/shadow cannot be retrieved. Testing confirmed
that the attack is not successful without the correct administrator
username and password.


Tested configurations
---------------------

Testing was performed with the following configurations:

  Critical Path inJoin V4.0 Directory Server
  Solaris 2.8


Vendor Response
---------------

Critical Path Inc:

Critical Path was contacted on April 30, 2002 and has implemented
preventative fixes for this issue.  A maintenance release to be known as
iCon 4.1.4.7 will be posted on the Critical Path support website at
http://support.cp.net, which is available to supported customers.  This
will be within the next few weeks, dependent upon other fixes that need to
be made available in this maintenance release.


Solution/Workaround
-------------------

Filter TCP port 1500 at the border to prohibit public access to the
Directory Server's administrative interface.

Use a strong password on the Directory Server administrator account and
change regularly. Distribute the password to only Directory Server
administrators.

Modify permissions on sensitive files to prohibit access by the ids user.

Though administration of the Directory Server over SSL is currently not
supported, Ciritical Path recommends the use of VPN software to mitigate
the risk of disclosure of the administrator username and password. The
next major release of the Critical Path Directory Server will features
SSL-enablement of the web-based management interface.

         Severity   : Low

Synopsis
--------

This advisory documents cross-site scripting vulnerabilities in the
Web-based administrator interface, named iCon, of the inJoin Directory
Server that allows an attacker with the correct username and password to
inject HTML script and use the server in a cross-site scripting attack.


Details
-------

The administrative web server, iCon, listens on TCP port 1500 and runs
under the ids account. By connecting to this port using a web browser and
entering a correct administrator username and password, an operator can
remotely administer the Directory Server. Testing of various
administrative URL's located situations in which script can be injected
and executed upon rendering of the response. Two examples are as follows,




Additional URL requests are also thought to be vulnerable. Testing
confirmed that the attack is not successful without the correct
administrator username and password.
