Pentest Security Advisory : PTL-2002-04
IBM Tivoli Management Framework Buffer Overflow (Endpoint)
Author: Mark Rowe
Announcement Date: 15th July 2002
Product: IBM Tivoli Management Framework
Vulnerable versions: 3.6.x through 3.7.1
Vulnerability Type : Buffer Overflow
Vendor-Status: Apply latest Fixpack (Currently Fixpack 2 or Patches 3.7.1-TMF-0066), or apply workaround.
A remote buffer overflow condition exists in the webserver (default port 9495) running on TMR Endpoints. This can result in a denial of service and execution of arbitrary code.
An overly long GET request results in a buffer overflow, with registers being overwritten with user supplied data.
This results in the TMR Endpoint Service crashing (LCFD process) and allows arbitrary code to be executed as a privileged user (SYSTEM on NT or root on Unix). The loss of the lcfd process terminates all endpoint activities.
Tested on: W2K and NT4 SP6a.
Apply latest Fixpack (Currently Fixpack 2 or Patches 3.7.1-TMF-0066), or apply workaround.
Tivoli were notified 12 April 2002.
Vendor has released a security alert with details of patches and workarounds. See http://www.tivoli.com/secure/support/documents/security/mgt-fwk-http-vul.html
