A vulnerability was found in F5 BIG-IP ASM up to 12.1.4/13.1.1.4/14.0.0.4/14.1.0.5 (Firewall Software). It has been rated as problematic. This issue affects some unknown functionality of the component REST Endpoint. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.

On BIG-IP (ASM) 14.1.0-14.1.0.5, 14.0.0-14.0.0.4, 13.0.0-13.1.1.4, and 12.1.0-12.1.4, Application logic abuse of ASM REST endpoints can lead to instability of BIG-IP system. Exploitation of this issue causes excessive memory consumption which results in the Linux kernel triggering OOM killer on arbitrary processes. The attack requires an authenticated user with role of "Guest" or greater privilege. Note: "No Access" cannot login so technically it's a role but a user with this access role cannot perform the attack.
The weakness was released 07/03/2019 (Website). The advisory is shared at support.f5.com. The identification of this vulnerability is CVE-2019-6637 since 01/22/2019.
