CVE-2025-6510Public exploitNetwork attack vector

Service crash via unbounded GET path copy

Published Jun 23, 2025 · Updated Jul 15, 2025

Stack-based buffer overflow in NETGEAR EX6100 1.0.2.28_1.1.138 allows remote authenticated users to crash the device via a crafted GET request. The sub_415EF8 routine passes data after GET /mtd to strcat without checking its effective 100-byte stack buffer. Access to the extender's HTTP service and low privileges are required; oversized path data corrupts the stack and interrupts service.
