Technical details

GeoVision GeoWebPlayer (also known as Web Plugin or WS Player) version 1.1.1.0 contains multiple out-of-bounds read and write vulnerabilities (CWE-129) within its WebSocket server functionality. The server accepts commands from localhost but fails to validate the 'index' field provided in JSON messages before using it to access internal arrays and critical sections. By staging a malicious webpage to send specially crafted WebSocket messages, a remote attacker can trigger these out-of-bounds accesses. This can result in the execution of arbitrary code via corrupted function pointers or unauthorized memory access. The vulnerability is addressed in version V1.1.3.0.
