QID 375678: F5 BIG-IP ASM,LTM,APM BIG-IP Linux Kernel Vulnerability (K51674118)
F5 BIG-IP ASM (Application Security Manager) is a flexible web application firewall that secures web applications in traditional, virtual, and private cloud environments.
F5 BIG-IP (LTM) Local Traffic Manager is the most popular module offered on F5 Networks BIG-IP platform. The real power of the LTM is it is a Full Proxy, allowing you to augment client and server side connections. All while making informed load balancing decisions on availability, performance, and persistence.
F5 BIG-IP Access Policy Manager (APM) is a secure, flexible, high-performance solution that provides unified global access to your network, cloud, and applications.
The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c. (CVE-2019-11599)
Vulnerable Component: BIG-IP ASM, APM,LTM
Affected Versions:
16.0.0 - 16.0.1
15.0.0 - 15.1.3
14.0.0 - 14.1.4.2
13.1.0 - 13.1.4.0
12.1.0 - 12.1.6
11.5.2 - 11.6.5
QID Detection Logic(Authenticated):
This QID checks for the vulnerable versions of F5 BIG-IP devices using the tmsh command.
A locally authenticated attacker can discover sensitive information, cause a denial of service (DoS), or impact the system in another way by triggering a race condition with the vulnerable component.
