BIG-IP version 16.0.x before 16.0.1.2, 15.1.x before 15.1.3, 14.1.x before 14.1.4.2, 13.1.x before 13.1.4.1, and all versions of 12.1.x and 11.6.x and all versions of BIG-IQ 8.x, 7.x, and 6.x are vulnerable to cross-site request forgery (CSRF) attacks through iControl SOAP. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
On all 7.x and 6.x versions (fixed in 8.0.0), BIG-IQ high availability (HA) when using a Quorum device for automatic failover does not implement any form of authentication with the Corosync daemon. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On BIG-IP version 16.0.x before 16.0.1.1, 15.1.x before 15.1.2, 14.1.x before 14.1.3.1, and 13.1.x before 13.1.3.6 and all versions of BIG-IQ 7.x and 6.x, an authenticated attacker with access to iControl REST over the control plane may be able to take advantage of a race condition to execute commands with an elevated privilege level. This vulnerability is due to an incomplete fix for CVE-2017-6167. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
On BIG-IP 15.0.0-15.0.1.2, 14.1.0-14.1.2.2, 13.1.0-13.1.3.2, 12.1.0-12.1.5, and 11.5.2-11.6.5.1 and BIG-IQ 7.0.0, 6.0.0-6.1.0, and 5.2.0-5.4.0, users with non-administrator roles (for example, Guest or Resource Administrator) with tmsh shell access can execute arbitrary commands with elevated privilege via a crafted tmsh command.
On BIG-IP 15.0.0-15.1.0.2, 14.1.0-14.1.2.3, 13.1.0-13.1.3.2, 12.1.0-12.1.5.1, and 11.5.2-11.6.5.1 and BIG-IQ 7.0.0, 6.0.0-6.1.0, and 5.2.0-5.4.0, in a High Availability (HA) network failover in Device Service Cluster (DSC), the failover service does not require a strong form of authentication and HA network failover traffic is not encrypted by Transport Layer Security (TLS).
An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP segments. If the Maximum Segment Size (MSS) of a TCP connection was set to low values, such as 48 bytes, it can leave as little as 8 bytes for the user data, which significantly increases the Linux kernel's resource (CPU, Memory, and Bandwidth) utilization. A remote attacker could use this flaw to cause a denial of service (DoS) by repeatedly sending network traffic on a TCP connection with low TCP MSS.
