CVE-2022-26130Network attack vector

Active FTP data-channel interruption via undisclosed traffic

Published May 5, 2022 · Updated Sep 16, 2024

Denial of service in F5 BIG-IP allows remote attackers to interrupt active FTP data-channel connections through a configured virtual server. F5 has not disclosed the traffic pattern or the FTP-processing operation that mishandles it; the result is refusal of new active-mode data channels. Exposure requires an Active mode-enabled FTP profile and affects 13.1.x before 13.1.5, 14.1.x before 14.1.4.6, 15.1.x before 15.1.5.1, and 16.1.x before 16.1.2.2.
