F5 BIG-IP appliances 9.x before 9.4.8-HF5, 10.x before 10.2.4, 11.0.x before 11.0.0-HF2, and 11.1.x before 11.1.0-HF3, and Enterprise Manager before 2.1.0-HF2, 2.2.x before 2.2.0-HF1, and 2.3.x before 2.3.0-HF3, use a single SSH private key across different customers' installations and do not properly restrict access to this key, which makes it easier for remote attackers to perform SSH logins via the PubkeyAuthentication option.

The iControl API in F5 BIG-IP LTM, APM, ASM, GTM, Link Controller, and PSM 10.0.0 through 10.2.4 and 11.0.0 through 11.5.1, BIG-IP AAM 11.4.0 through 11.5.1, BIG-IP AFM and PEM 11.3.0 through 11.5.1, BIG-IP Analytics 11.0.0 through 11.5.1, BIG-IP Edge Gateway, WebAccelerator, WOM 10.1.0 through 10.2.4 and 11.0.0 through 11.3.0, Enterprise Manager 2.1.0 through 2.3.0 and 3.0.0 through 3.1.1, and BIG-IQ Cloud, Device, and Security 4.0.0 through 4.3.0 allows remote administrators to execute arbitrary commands via shell metacharacters in the hostname element in a SOAP request.

The Traffic Management Microkernel (TMM) in F5 BIG-IP LTM, APM, ASM, Edge Gateway, GTM, Link Controller, and WOM 10.0.0 through 10.2.2 and 11.0.0; Analytics 11.0.0; PSM 9.4.0 through 9.4.8, 10.0.0 through 10.2.4, and 11.0.0 through 11.4.1; and WebAccelerator 9.4.0 through 9.4.8, 10.0.0 through 10.2.4, and 11.0.0 through 11.3.0 might change a TCP connection to the ESTABLISHED state before receiving the ACK packet, which allows remote attackers to cause a denial of service (SIGFPE or assertion failure and TMM restart) via unspecified vectors.

Buffer overflow in the bd daemon in F5 Networks BIG-IP Application Security Manager (ASM) 9.4.4 through 9.4.7 and 10.0.0 through 10.0.1, and Protocol Security Manager (PSM) 9.4.5 through 9.4.7 and 10.0.0 through 10.0.1, allows remote attackers to cause a denial of service (crash) via unknown vectors.
