IBM Tivoli Directory Server Multiple Flaws Let Remote Authenticated Users Execute Arbitrary Commands, Remote Users Obtain Information and Conduct Cross-Site Scripting Attacks, and Local Users Obtain Information
SecurityTracker Alert ID:  1032734
SecurityTracker URL:  http://securitytracker.com/id/1032734
CVE Reference:   CVE-2015-1959, CVE-2015-1972, CVE-2015-1974, CVE-2015-1978, CVE-2015-2019, CVE-2015-2808   (Links to External Site)
Date:  Jun 26 2015
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 6.0, 6.1, 6.2, 6.3, 6.3.1, 6.4
Description:   Multiple vulnerabilities were reported in IBM Tivoli Directory Server. A remote authenticated user can execute arbitrary commands on the target system. A remote user can conduct cross-site scripting attacks. A local user can access potentially sensitive files on the target system. A remote user can obtain potentially sensitive information on the target system.

The software does not properly filter HTML code from user-supplied input before displaying the input [CVE-2015-1978]. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the IBM Tivoli Directory Server software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can submit a specially crafted HTTP POST request to obtain potentially sensitive information from the target system [CVE-2015-1972].

A local user can upload and download potentially sensitive encrypted files [CVE-2015-1959].

A remote authenticated user can exploit an access control flaw in the web administration tool to execute arbitrary commands on the target system [CVE-2015-1974].

A local user can access some cached SSL pages to obtain potentially sensitive information [CVE-2015-2019].

A remote user that can monitor TLS network traffic can obtain RC4 encrypted data and conduct a brute-force key guessing attack against RC4 to decrypt the data [CVE-2015-2808].

Impact:   A remote authenticated user can execute arbitrary commands on the target system.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the IBM Tivoli Directory Server software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

A remote user can obtain potentially sensitive information from the target system.

A remote user can obtain potentially sensitive information communicated by target system.

A local user can obtain or modify potentially sensitive information.

Solution:   The vendor has issued a fix (6.0 iFix 75, 6.1 iFix 68, 6.2 iFix 44, 6.3 iFix 37, 6.3.1 iFix 11, 6.4 iFix 2).

Vendor URL:  www-01.ibm.com/support/docview.wss?uid=swg21960659 (Links to External Site)
Cause:   Access control error, Input validation error
Underlying OS:  Linux (Any), UNIX (AIX), UNIX (HP/UX), UNIX (Solaris - SunOS), Windows (2003), Windows (2008)

Message History:   None.
