CVE-2026-57266: CWE-129 Improper validation of array index 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. Many of the commands will take an `index` value that is then used to access various arrays to enter critical sections, perform various actions via function calls, etc. However the `index` value is usually not checked for valid range, and as such it can be used to access multiple arrays out-of-bound. #### 2wayAudio command index-out-of-bound
AI Analysis
Technical Summary
GeoWebPlayer, an addon for GeoVision software, runs a Websocket server that processes commands from localhost. Many commands use an 'index' parameter to access arrays without proper bounds checking, resulting in multiple out-of-bound array accesses. This improper validation (CWE-129) can cause critical security issues affecting confidentiality, integrity, and availability. The vulnerability is identified in version V1.1.1.0. There is no vendor-provided remediation or patch information at this time.
Potential Impact
Exploitation of this vulnerability can lead to unauthorized access or manipulation of memory outside intended bounds, potentially allowing attackers to execute arbitrary code, cause denial of service, or leak sensitive information. The CVSS 3.1 score of 8.3 reflects high impact on confidentiality, integrity, and availability. However, exploitation requires local access (localhost) and user interaction (UI:R).
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 localhost interface of the GeoWebPlayer Websocket server to trusted users only. Monitor for vendor updates regarding patches or official mitigations.
