Executive brief
GeoWebPlayer is a browser plugin used with GeoVision video management software to enable web-based viewing of security camera feeds. A security flaw allows an attacker to trick a user into visiting a malicious website, which can then send unauthorized commands to the plugin. This could allow the attacker to take control of the user's computer or disrupt the video surveillance system.
Technical details
GeoVision GeoWebPlayer (version 1.1.1.0) contains multiple out-of-bounds (OOB) vulnerabilities within its WebSocket server, which handles commands like connectInfo, setStream, and audio. The root cause is improper validation of the 'index' field in incoming JSON messages, which is used to access internal arrays (such as array_of_IPCams and crit_sections) without bounds checking. An attacker can exploit this by hosting a malicious webpage that sends specially crafted WebSocket messages to the local server. This can result in OOB writes or the execution of arbitrary function pointers, potentially leading to remote code execution (RCE). The vulnerability is addressed in version V1.1.3.0.
