Affected is an unknown code block of the component Traffic Management Microkernel. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently.

On BIG-IP 15.0.0-15.0.1.3, 14.1.0-14.1.2.3, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1, a race condition exists where mcpd and other processes may make unencrypted connection attempts to a new configuration sync peer. The race condition can occur when changing the ConfigSync IP address of a peer, adding a new peer, or when the Traffic Management Microkernel (TMM) first starts up.
The weakness was released 04/30/2020. This vulnerability is traded as CVE-2020-5876 since 01/06/2020. The exploitability is told to be difficult. It is possible to launch the attack remotely.
