AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Remote, no-auth, low-complexity HTTP request triggers a crash (AV:N/AC:L/PR:N/UI:N); impact is availability-only DoS, so C:N/I:N/A:H with unchanged scope.

Lifecycle Timeline
1DescriptionCVE.org
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.
AnalysisAI
Denial of service in GeoVision GV-LPC2011 and GV-LPC2211 license-plate capture devices (firmware V1.12 and earlier) lets a remote, unauthenticated attacker crash the device by sending a single malformed HTTP request to its CGI interface. The flaw is a NULL pointer dereference in HTTP request-parsing logic shared across multiple CGI components, triggered when required request metadata is missing or malformed. No public exploit identified at time of analysis, and the issue has no confidentiality or integrity impact - only availability.
Technical ContextAI
The affected devices are GeoVision GV-LPC (License Plate Capture/Recognition) embedded camera/controller units that expose a web management interface backed by CGI components. CWE-476 (NULL Pointer Dereference) describes the root cause: the CGI HTTP parser reads pointers derived from request metadata (such as headers or content fields) without first validating that those values are present and non-null, then dereferences them. When an attacker omits or corrupts that expected metadata, the process dereferences a NULL pointer and crashes. Because the same defective parsing routine is reused across several CGI endpoints, multiple request paths can reach the bug, increasing the attack surface on the embedded HTTP service.
RemediationAI
No vendor-released patch version is identified in the available data; the only reference is GeoVision's general security advisory page (https://www.geovision.com.tw/cyber_security.php), which should be checked for a firmware build newer than V1.12 and applied once available. As compensating controls until a fixed firmware is confirmed: remove the devices' web/CGI interface from internet exposure and place them on a segmented management VLAN, restricting TCP access to the HTTP(S) management port to a small set of trusted administrative hosts via firewall ACLs (trade-off: legitimate remote management must come through a VPN or jump host). Place a reverse proxy or WAF in front of the CGI interface to enforce well-formed HTTP requests and reject those missing required headers/metadata (trade-off: added latency and maintenance, and it may not block every malformed-request variant). Monitor for unexpected device reboots/crashes as a detection signal, since exploitation manifests as service disruption.
