CVE-2023-21406 is a critical heap-based buffer overflow vulnerability affecting AXIS A1001 door controllers when communicating via OSDP. An attacker can exploit this flaw by sending specially crafted OSDP messages with invalid data, causing the pacsiod process to write beyond its allocated buffer. This can lead to arbitrary code execution, allowing an attacker to gain full control over the device. With a CVSS score of 8.8 (High), this vulnerability presents a significant risk due to its network-adjacent attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While there is no evidence of active exploitation or public exploit code, the vulnerability has garnered some community discussion and media coverage, indicating awareness within the security community.
