Overview:
The IBM Lotus Domino Web Server service is vulnerable to a stack based buffer overflow which can be exploited remotely. Upon reporting this issue to IBM it was discovered that this was a known issue which had been resolved in a number of previous releases and Fix Packs. However, the previously reported issue did not correctly assess the impact of the vulnerability or provide a description that allowed the vulnerability of a given system to be accurately assessed.
Impact:
The vulnerability would enable an attacker to execute arbitrary code on a system. In the majority of installations this would be with local SYSTEM privileges.
Cause:
The code responsible for parsing a parameter within the HTTP header of requests to the service does not adequately check user supplied input. This results in the ability to overflow a stack buffer which in turn allows arbitrary code to be executed.
