Received Received - Intake
Stack-Based Buffer Overflow in GeoVision GV-LPC2011 and GV-LPC2211

Publication date: 2026-06-26

Last updated on: 2026-06-26

Assigner: 0df08a0e-a200-4957-9bb0-084f562506f9

Description
An unauthenticated stack-based buffer overflow vulnerability exists in ssvr in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing RTSP custom authentication data. A remote attacker may exploit this vulnerability by sending a crafted RTSP request, resulting in memory corruption, denial of service, or potentially arbitrary code execution.

Executive Summary

This vulnerability is an unauthenticated stack-based buffer overflow in the ssvr component of GeoVision GV-LPC2011 and GV-LPC2211 devices running version 1.12 or earlier. It occurs due to insufficient bounds checking when processing RTSP custom authentication data.

A remote attacker can exploit this by sending a specially crafted RTSP request, which can cause memory corruption.

The consequences of this memory corruption include denial of service or potentially arbitrary code execution on the affected device.

Impact Analysis

Exploitation of this vulnerability can lead to serious impacts including denial of service, which would disrupt the normal operation of the affected device.

More severely, it may allow an attacker to execute arbitrary code remotely without authentication, potentially leading to full compromise of the device.

This could result in unauthorized control, data theft, or further attacks within the network where the device is deployed.

Compliance Impact

The provided information does not explicitly address how this vulnerability impacts compliance with common standards and regulations such as GDPR or HIPAA.

Mitigation Strategies

To mitigate this vulnerability, it is important to apply any security updates or patches provided by GeoVision as soon as they become available.

GeoVision follows a structured vulnerability management process that includes prompt release of unscheduled updates for critical vulnerabilities such as this one.

Users should monitor GeoVision's official cybersecurity advisories and update their GV-LPC2011 and GV-LPC2211 devices to the latest firmware versions to address this stack-based buffer overflow vulnerability.
