CVE-2026-57273: CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in GeoVision Inc. GeoWebPlayer
CVE-2026-57273 is a high-severity buffer overflow vulnerability in GeoVision Inc.'s GeoWebPlayer version 1.1.1.0. The vulnerability exists in the websocket server component, specifically in the handler for the 'connectionInfo' command, which processes attacker-controlled JSON strings. The function handle_connection_info copies these strings into fixed-size buffers without proper length checks, leading to classic buffer overflow conditions. This flaw can result in complete compromise of confidentiality, integrity, and availability of the affected system. No official patch or remediation guidance is currently available from the vendor.
AI Analysis
Technical Summary
GeoWebPlayer 1.1.1.0 contains a classic buffer overflow vulnerability (CWE-120) in the websocket server's 'connectionInfo' command handler. The function handle_connection_info copies attacker-controlled JSON data into fixed-size buffers using manual byte-by-byte loops that lack length enforcement, allowing overflow. This can lead to severe impacts including full compromise of the system's confidentiality, integrity, and availability. The vulnerability is remotely exploitable over the network but requires user interaction (UI:R) and has a high attack complexity (AC:H). No vendor-provided patch or mitigation is currently documented.
Potential Impact
Successful exploitation of this vulnerability can lead to complete compromise of the affected system, including unauthorized disclosure of information, modification of data, and denial of service. The CVSS v3.1 base score is 8.3 (high), reflecting network attack vector, high complexity, no privileges required, user interaction required, and complete impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit access to the GeoWebPlayer websocket server to trusted users and networks only. Monitor for unusual activity related to the 'connectionInfo' command. Avoid exposing the websocket server to untrusted networks. Follow vendor communications for updates on official patches or mitigations.
