CVE-2026-57277: CWE-120 - Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in GeoVision Inc. GeoWebPlayer
CVE-2026-57277 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 can result in complete compromise of confidentiality, integrity, and availability of the affected system. No official patch or remediation guidance is currently available.
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 capabilities. In version 1.1.1.0, the 'handle_connection_info' function processes the 'connectionInfo' command by copying JSON strings into fixed-size buffers using manual byte-by-byte loops without length checks. This improper handling leads to a classic buffer overflow (CWE-120) vulnerability. The vulnerability allows remote attackers to cause memory corruption with high impact on confidentiality, integrity, and availability. The CVSS 3.1 base score is 8.3, indicating high severity. No patch or official remediation is currently documented.
Potential Impact
Successful exploitation of this buffer overflow vulnerability can lead to complete compromise of the affected system's confidentiality, integrity, and availability. Attackers may execute arbitrary code, cause denial of service, or escalate privileges via crafted JSON input to the websocket server's 'connectionInfo' command handler. The vulnerability requires network access but has a high attack complexity and requires user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the GeoWebPlayer websocket server to trusted hosts only, especially limiting localhost command acceptance if possible. Monitor for updates from GeoVision Inc. regarding patches or official mitigations.
