Description:
Luigi Auriemma has discovered a vulnerability in PRISM Guard Shield, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the processing of network packets by the included Asura engine when PRISM Guard Shield runs as a server. This can be exploited to cause a stack-based buffer overflow via a specially crafted packet with a type of "0xF007" sent to the vulnerable server (default port 3658/udp).
The vulnerability is confirmed in PRISM Guard Shield version 1.1.2.3 and is reported in version 1.1.1.0. Other versions may also be affected.
Solution:
Use PRISM Guard Shield as a multiplayer server only in a trusted network environment.
