CVE-2026-57274: CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in GeoVision Inc. GeoWebPlayer
GeoWebPlayer (also called "Web Plugin" in the GV-VMS documentation and "WS Player" for VMS-Cloud) is an addon that can be installed with various GeoVision software (GV-VMS, GV-Cloud, ...). It creates a websocket server that expands the capabilities of the various web-interfaces provided by the GeoVision software and may be necessary for them to function properly. The Websocket server can accept various commands coming from localhost. One of them, `connectionInfo` is meant to provide the necessary details to connect to a camera. The handler associated with this command that we call`handle_connection_info` contains multiple instances of string copy that can overflow. The function `handle_connect_info` copies attacker-controlled JSON strings into fixed-size buffers using manual byte-by-byte loops that do not enforce length limits. #### Buffer Overflow in password field (no key present)
AI Analysis
Technical Summary
GeoWebPlayer's websocket server accepts commands from localhost, including 'connectionInfo' which provides camera connection details. The handler function 'handle_connection_info' copies JSON strings into fixed-size buffers using manual byte-by-byte loops without proper length checks, leading to buffer overflow (CWE-120). This vulnerability affects GeoWebPlayer version V1.1.1.0 and can result in high impact on confidentiality, integrity, and availability as indicated by a CVSS 3.1 score of 8.3 with network attack vector, high attack complexity, no privileges required, user interaction required, and scope changed.
Potential Impact
Successful exploitation can lead to arbitrary code execution or denial of service due to buffer overflow in the password field of the connectionInfo command handler. The vulnerability compromises confidentiality, integrity, and availability of the system running GeoWebPlayer V1.1.1.0. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict access to the localhost websocket server and monitor for suspicious activity related to the connectionInfo command.
