CVE-2026-57875 in GV-LPCLPC2011
Summary
by MITRE • 06/26/2026
An unauthenticated NULL pointer dereference vulnerability exists in the HTTP request parsing logic of multiple CGI components in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by improper validation of required HTTP request metadata before it is used by the affected components. A remote attacker may exploit this vulnerability by sending a specially crafted HTTP request, causing the affected process to crash and resulting in a denial of service.

This vulnerability represents a critical NULL pointer dereference flaw within the HTTP request processing subsystem of GeoVision GV-LPC2011 and GV-LPC2211 devices running firmware versions 1.12 and earlier. The issue stems from inadequate input validation mechanisms that fail to properly examine essential HTTP request metadata before subsequent processing occurs. This fundamental weakness creates a pathway for remote exploitation where malicious actors can manipulate the device's web server functionality through crafted HTTP requests. The vulnerability manifests specifically within CGI components responsible for handling web-based administrative and operational communications, making it particularly dangerous as it affects core device management interfaces.
The technical implementation of this flaw demonstrates poor defensive programming practices where the software assumes certain request parameters will always contain valid data without proper validation checks. When an attacker sends a malformed HTTP request containing NULL or missing metadata fields, the parsing logic attempts to dereference these uninitialized pointers, leading to immediate process termination and system instability. This behavior aligns with CWE-476 which specifically addresses NULL pointer dereference vulnerabilities in software systems. The vulnerability's impact extends beyond simple denial of service as it represents a fundamental architectural weakness that could potentially allow for more sophisticated attacks if the device's memory management is not properly secured.
From an operational perspective, this vulnerability creates significant risk for organizations relying on these security devices as it allows remote attackers to disrupt critical surveillance infrastructure without requiring authentication credentials. The attack vector is particularly concerning because it operates at the network level and can be executed from any location with internet connectivity to the affected device. This makes it an attractive target for both opportunistic attacks and coordinated campaigns against security infrastructure. The denial of service impact directly affects business continuity by potentially disabling video monitoring capabilities, creating blind spots in security coverage that attackers could exploit.
The mitigation strategy should focus on immediate firmware updates from GeoVision addressing the root cause through proper input validation mechanisms and pointer initialization checks. Organizations must also implement network segmentation to limit access to these devices while awaiting patches, along with monitoring for unusual HTTP traffic patterns that might indicate exploitation attempts. Additional defensive measures include configuring firewalls to restrict access to device management interfaces and implementing intrusion detection systems that can identify crafted HTTP requests targeting this specific vulnerability pattern. This vulnerability highlights the importance of robust input validation practices in embedded systems as outlined in the OWASP Top Ten and aligns with ATT&CK technique T1499 which covers network denial of service attacks against critical infrastructure components.
