CVE-2025-41418Network attack vector

CGI process crash via crafted request

Published Jun 27, 2025 · Updated Jun 30, 2025

Classic buffer overflow in the CGI process of TB-eye network and AHD recorders allows remote attackers to crash the process via a crafted request. Public advisories do not identify the CGI endpoint, input field, or unchecked copy operation that overruns the buffer. No authentication or user interaction is required, and the published impact for this flaw is limited to interruption of the CGI process.
