CVE-2020-15892 describes a critical stack-based buffer overflow vulnerability in D-Link DAP-1520 devices (firmware versions prior to 1.10b04Beta02). This flaw arises from insufficient server-side validation of input fields (log_pass, html_response_page, log_user) during web interface login, allowing an attacker to bypass client-side length restrictions. With a CVSS score of 9.8 (CRITICAL), this vulnerability is remotely exploitable with low attack complexity, potentially leading to complete compromise of confidentiality, integrity, and availability. While there is no known active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered some community discussion and media coverage, indicating awareness.
