4Description
A vulnerability was found in Netgear EX6100 1.0.2.28_1.1.138. It has been rated as critical. Affected by this issue is the function sub_415EF8. The manipulation leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.
Analysis
CVE-2025-6510 is a critical stack-based buffer overflow vulnerability in Netgear EX6100 WiFi extender (version 1.0.2.28_1.1.138) affecting the sub_415EF8 function. An authenticated remote attacker can exploit this vulnerability to achieve arbitrary code execution with high integrity and availability impact. The vulnerability has public exploit disclosure and affects only end-of-life products no longer receiving vendor support.
Technical Context
This vulnerability is a stack-based buffer overflow (CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer) in the Netgear EX6100 WiFi range extender firmware. The vulnerable function sub_415EF8 fails to properly validate input boundaries before writing to stack memory, allowing an attacker to overwrite the stack frame and potentially achieve code execution. The EX6100 is a consumer-grade WiFi extender running proprietary firmware; the vulnerability exists in low-level network processing or configuration parsing routines. CPE identifier would be: cpe:2.3:h:netgear:ex6100:1.0.2.28_1.1.138:*:*:*:*:*:*:* with corresponding firmware CPE for the affected version.
