CVE-2025-52082Public exploitNetwork attack vector

Authenticated code execution via unchecked strcpy

Published Jul 15, 2025 · Updated Jul 15, 2025

Stack-based buffer overflow in Netgear XR300 1.0.3.38_10.3.30 allows remote authenticated users to execute code via read_access. The usb_device.cgi handler copies user-controlled read_access data into a 96-byte stack buffer with strcpy despite accepting up to 2,048 bytes. Valid HTTP Basic credentials are required; overwriting the return address grants control of execution in the router's HTTPD process.
