CVE-2022-27612Network attack vector

Unauthenticated command execution via unchecked CGI buffer copy

Published Jul 28, 2022 · Updated Sep 17, 2024

Classic buffer overflow in Synology Audio Station before 6.5.4-3367 allows remote attackers to execute arbitrary commands through its CGI component. The CGI component copies attacker-controlled input into a buffer without checking its size, allowing the destination buffer to overflow. No authentication or user interaction is required, but Synology has not disclosed the request parameter or CGI endpoint needed to reach the copy operation.
