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.

  1. 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

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.
