Title: Sambar Server Authentication Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
Sambar Server is a multi-threaded web server which will run on Microsoft Windows 9x/ME/NT/2000 operating systems.
A buffer overflow vulnerability has been reported in some versions of Sambar Server. If extremely long strings are sent for the username and password used for authentication, it is possible to overwrite stack memory. It is possible to overwrite stack frame data, which can lead to the execution of arbitrary code.
As the Sambar server runs with SYSTEM privileges, exploitation of this vulnerability can lead to remote access to the system with administrative privileges.
Less clever exploitation of this vulnerability may cause the Sambar process to crash, resulting in a denial of service attack.
