About Geovision Gv-Lpc2011 Firmware

CVE-2026-42364 affects Geovision Gv-Lpc2011 Firmware, a product from Geovision. Before acting, confirm where Geovision Gv-Lpc2011 Firmware runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.

What the flaw is

In plain terms: An os command injection vulnerability exists in the DdnsSetting.cgi functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted DDNS configuration can lead to arbitrary command execution. An attacker can modify a configuration value to trigger this vulnerability.

The weakness class is OS Command Injection. Untrusted input is passed to the operating system shell, letting an attacker run commands.

Based on its CVSS vector, the flaw can be reached over the network, needs some level of access, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it

  • Inventory every instance of Geovision Gv-Lpc2011 Firmware and record the running version against the affected range above.
  • Check external attack surface scans for internet facing instances of the component.
  • Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
  • Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.

How to fix it

  • Apply the fixed version of Geovision Gv-Lpc2011 Firmware named in the vendor advisory.
  • If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
  • Rescan after the change to prove the exposure is gone, then close the ticket.

CVE-2026-7372
Geovision Gv-Vms Firmware

A stack overflow vulnerability exists in the WebCam Server Login functionality of GeoVision GV-VMS V20 20.0.2. A specially crafted HTTP request can lead to an arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger this vulnerability. #### Stack-overflow via unconstrained sscanf The call to `sscanf` at [1] to split the `Buffer` variable into the `username` and `password` variables doesn't limit the size of the extracted content to match the destination buffers' sizes. In this case, if either the username or password decoded from the authorization string exceeds `40` characters (the size the stack variables `username` and `password`) then a stack overflow will occur. The data is controlled by an attacker, but sronger constraints (e.g. no null bytes) may make exploitation harder. A successful attack could lead to full code execution as SYSTEM on the machine running the service.
