CVE-2021-27248 is a critical stack-based buffer overflow vulnerability affecting D-Link DAP-2020 v1.01rc001 Wi-Fi access points, specifically within the processing of CGI scripts when handling the 'getpage' parameter. This flaw allows unauthenticated, network-adjacent attackers to execute arbitrary code with root privileges due to insufficient validation of user-supplied data length. With a CVSS score of 8.8 (HIGH), it presents a significant risk as it requires no authentication or user interaction for exploitation, and has a high impact on confidentiality, integrity, and availability. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), it is not listed in CISA's KEV, and it has received no community discussion or media coverage, suggesting a low current exploitation status.
