CVE-2026-57274: CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in GeoVision Inc. GeoWebPlayer
CVE-2026-57274 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 that handles commands from localhost, specifically in the 'connectionInfo' command handler. This handler copies attacker-controlled JSON strings into fixed-size buffers without enforcing length limits, leading to classic buffer overflow conditions. The flaw affects the password field when no key is present, potentially allowing an attacker to execute arbitrary code or cause denial of service.
AI Analysis
Technical Summary
GeoWebPlayer (also known as Web Plugin or WS Player) is an addon for GeoVision software that provides a websocket server for enhanced web interface functionality. In version 1.1.1.0, the 'handle_connection_info' function processes the 'connectionInfo' command by copying JSON input into fixed-size buffers using manual byte-by-byte loops without proper length checks. This results in a classic buffer overflow (CWE-120) vulnerability in the password field when no key is present. The vulnerability has a CVSS 3.1 base score of 8.3, indicating high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation of this buffer overflow vulnerability can lead to complete compromise of the affected system, including arbitrary code execution, data corruption, and denial of service. The vulnerability affects confidentiality, integrity, and availability with high severity. However, exploitation requires local access (network attack vector is network but with high attack complexity and user interaction required).
Mitigation Recommendations
No official patch or remediation is currently available for this vulnerability. Users should monitor the vendor's advisory for updates and apply any official fixes once released. Until then, restrict access to the localhost websocket server component and limit user interaction with the vulnerable command to reduce risk.
