CVE-2026-88280 Overview
CVE-2026-88280 is a stack-based buffer overflow [CWE-121] affecting the GeoVision GV-LPC2211 license plate capture device running firmware version V1.13. The device copies an oversized ONVIF SetUser password value into a fixed-size stack field inside the ONVIF worker process. An authenticated administrator can send a crafted request that overruns the buffer and crashes the worker, disrupting ONVIF video and configuration services.
Critical Impact
An authenticated administrator can remotely crash the ONVIF worker on GeoVision GV-LPC2211 V1.13, causing a denial-of-service condition on the affected camera.
Affected Products
- GeoVision GV-LPC2211 firmware V1.13
- GeoVision ONVIF worker component on GV-LPC2211
- Deployments exposing the ONVIF service to administrator-reachable networks

Technical Details for CVE-2026-88280
Vulnerability Analysis
The flaw resides in the ONVIF worker handling of the SetUser operation on the GV-LPC2211 V1.13 firmware. The handler accepts a password string from an authenticated administrator and copies it into a fixed-size buffer located on the stack. The copy operation does not validate the input length against the destination size.
When an oversized password is supplied, the copy overruns the adjacent stack region. The corruption destabilizes execution state within the ONVIF worker and terminates the process. The result is loss of ONVIF-based control, configuration, and streaming until the worker restarts.
Exploitation requires valid administrator credentials, which limits the attack surface to trusted operators or attackers who have already obtained privileged access. The impact is confined to availability; confidentiality and integrity are not directly affected.
Root Cause
The root cause is a classic stack-based buffer overflow [CWE-121]. The ONVIF worker uses an unchecked copy of user-controlled data into a fixed stack allocation. Missing bounds validation on the ONVIF SetUser password field allows any input larger than the destination buffer to corrupt the stack frame.
Attack Vector
The vulnerability is reachable over the network on the ONVIF service port. An authenticated administrator issues a standard ONVIF SetUser SOAP request with a password value crafted to exceed the internal buffer size. Processing the request causes the ONVIF worker to crash, producing a denial of service on the device.
No verified public exploit or proof-of-concept code is available for CVE-2026-88280. Technical details should be obtained from the GeoVision Cyber Security Resources advisory page.
Detection Methods for CVE-2026-88280
Indicators of Compromise
- Repeated unexpected termination or restart of the ONVIF worker process on GV-LPC2211 devices running firmware V1.13.
- ONVIF SetUser SOAP requests containing abnormally long password fields captured in network traffic.
- Loss of ONVIF service availability shortly after administrator-authenticated ONVIF requests from unusual source addresses.
Detection Strategies
- Inspect HTTP or HTTPS traffic destined for the ONVIF service and flag SetUser requests where the password element exceeds normal length thresholds.
- Correlate ONVIF administrator authentication events with subsequent device unavailability or service restart telemetry.
- Alert on repeated administrator logins from new or geographically anomalous source addresses to camera management interfaces.
Monitoring Recommendations
- Monitor GV-LPC2211 device health and ONVIF port reachability from your network management system.
- Forward camera and switch logs to a central platform such as Singularity Data Lake to correlate ONVIF request patterns with device outages.
- Track administrator credential usage for camera fleets and alert on off-hours configuration activity.
How to Mitigate CVE-2026-88280
Immediate Actions Required
- Restrict ONVIF service exposure so only trusted management hosts can reach GV-LPC2211 devices on the ONVIF port.
- Rotate GV-LPC2211 administrator credentials and remove unused administrator accounts to reduce the authenticated attack surface.
- Review the GeoVision Cyber Security Resources page for firmware updates addressing CVE-2026-88280 and plan deployment.
Patch Information
At the time of publication, no specific patched firmware version is listed in the NVD record for CVE-2026-88280. Consult the GeoVision Cyber Security Resources page for the current advisory and any firmware release that supersedes V1.13 on the GV-LPC2211.
Workarounds
- Place GV-LPC2211 cameras on a segmented management VLAN with access control lists limiting ONVIF traffic to authorized video management systems.
- Enforce strong, unique administrator passwords and require multi-factor authentication on jump hosts used to administer camera fleets.
- Disable the ONVIF service on devices where it is not required by the video management platform.
