IBM Tivoli Management Framework Buffer Overflow (ManagedNode) Announcement date: 15th July 2002 Reference: ptl-2002-05 Advisory Details ---------------- Product: IBM Tivoli Management Framework Vulnerable versions: 3.6.x through 3.7.1 Vulnerability Type : Buffer Overflow Platforms: All Vendor-URL: http://www.tivoli.com Vendor-Status: A fix is forthcoming in Version 4.1. A workaround is available for earlier versions. Remote-Exploit: Yes Overview -------- A remote buffer overflow condition exists in the webserver (default port 94 but redirects to another port) running on TMR ManagedNodes. This results in a denial of service and the possibility of arbitrary code execution. Description ----------- An overly long GET request results in a buffer overflow, with registers being overwritten with user supplied data. This results in the TMR ManagedNode HTTPd daemon crashing (Spider process) and allows arbitrary code to be executed as a privileged user (SYSTEM on NT or root on Unix). The loss of the spider process will prevent all http requests to that ManagedNode, but does not impact all other Framework or application functions. Tested on: Solaris8 (Sparc). Fix --- Apply workaround. Vendor status ------------- Tivoli were notified 12 April 2002. Vendor has released a security alert with details of patches and workarounds.
