What is CVE-2025-6292?

A stack-based buffer overflow vulnerability has been identified in the D-Link DIR-825 router, specifically within the HTTP POST Request Handler function. This security flaw arises from improper handling of input, allowing an attacker to send specially crafted requests that exploit the vulnerability to execute arbitrary code remotely. The affected firmware version 2.03 is no longer supported by D-Link, which increases the risk of exploitation as no patches or updates will be provided. Organizations using this device should consider replacement or urgent mitigation strategies.
