About Geovision Gv-Lpc2011 Firmware

CVE-2026-42365 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: A guessable session cookie vulnerability exists in the Web Interface functionality of GeoVision LPC2011/LPC2211 1.10. A specially crafted series of HTTP requests can lead to an authentication bypas. An attacker can bruteforce session cookies to trigger this vulnerability.

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

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.
