Technical details

An improper validation of array index (CWE-129) exists in the WebSocket server functionality of GeoVision GeoWebPlayer version 1.1.1.0. The vulnerability occurs when processing the 'pause' command (and other similar commands like connectInfo and setStream), where an 'index' field is extracted from a JSON-formatted WebSocket message and used to access internal arrays without proper bounds checking. By providing a specially crafted index value, an attacker can trigger an out-of-bounds read or write, potentially leading to the execution of arbitrary code via corrupted function pointers. Exploitation requires the victim to visit a malicious website that communicates with the local WebSocket server. The issue is addressed in version V1.1.3.0.
