  Vulnerability Report For iPlanet CMS and Netscape Directory Server

Date Published: 2000-10-26

Advisory ID: CORE-2000-10-26

Bugtraq ID: 1839

CVE CAN: Non currently assigned.

Title: Path traversal and administrator password in clear text
vulnerabilities

Class: Access Validation Error/Design Error

Remotely Exploitable: Yes

Locally Exploitable: Yes

Vulnerability Description:

 Netscape (iPlanet) Certificate Management System, Netscape
 Directory Server and Netscape Administration Servers share components which
 suffer from two notable vulnerabilities.

1. Path Traversal Vulnerability

 The first vulnerability is a classic path traversal vulnerability
 whereby a user can supply a crafted URL and access files outside the web
root
 directory. This will result in the remote user being able to read/download
 any files which the server itself (based on it's permissions) may access.

2. Admininistrator password is stored in clear text

 The 'Admin' password for these packages is stored in plaintext in
 admin-serv\config\adm.conf. This in addition to the previous
 vulnerability will allow anyone to obtain the password remotely and
 perform admin duties if net access to the admin server is
 available

Vulnerable Packages/Systems:

  Netscape Certificate Management System 4.2 (MS Windows NT 4.0 version)
  Netscape Directopy Server 4.12 (MS windows NT 4.0 version)

Solution/Vendor Information/Workaround:

 Contact the vendor for a fix. Patches for IPlanet products
 can be obtained from
  http://www.iplanet.com/downloads/patches.index.html

 This advisory was drafted with the help of the SecurityFocus.com
 Vulnerability Help Team. For more information or assistance drafting
advisories
 please mail vulnhelpsecurityfocus.com.

Technical Description - Exploit/Concept Code:

 Several components installed by CMS 4.2 for Windows NT 4.0 allow an
attacker
 to read/download any file outside the web root directory provided that
access
  to any of the following servers is given:
 - The Agent services server on port 8100/tcp
 - The End Entity services server on port 443/tcp (This is normally
   accessable for any user over SSL)
 - The Administrator services server listening on a random port
   choosen during the installation process, or on port 8200 if
   configured to do so (not the default behavior).

   By using '\../' in the URI an attacker can get out
   of the server's root directory and open any file.
   The following example demostrates the problem using the
   End Entity services server:

   A request for https://server/ca/\../\../\../\../\../\win.ini will
   open and display the requested file

 . Admin password is stored in plantext in admin-serv\config\adm.conf.
   This in addition to the previous bug will allow anyone to obtain the
password
   remotely and perform admin duties if net access to the admin server is
   available.
