Title: Fujitsu Systemcast Wizard Lite PXE Request Remote Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
Fujitsu Systemcast Wizard Lite is a support application for Fujitsu PRIMEQUEST servers.
Systemcast Wizard Lite is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Specifically, Pre-Boot Execution Environment (PXE) requests received by the 'PXEService.exe' service are copied to a statically sized buffer without sufficient validation. An attacker can exploit this issue by sending a maliciously crafted UDP packet containing a PXE request of over 1024 bytes.
Attackers can leverage this issue to execute arbitrary code with SYSTEM-level privileges. Successful exploits will compromise the application and the underlying computer. Failed attacks will cause denial-of-service conditions.
Systemcast Wizard Lite 2.0A and prior are vulnerable.
