CVE-2016-6876
The RESOLV::lookup iRule command in F5 BIG-IP LTM, APM, ASM, and Link Controller 10.2.1 through 10.2.4, 11.2.1, 11.4.x, 11.5.x before 11.5.4 HF2, 11.6.x before 11.6.1, and 12.0.0 before HF3; BIG-IP AAM, AFM, and PEM 11.4.x, 11.5.x before 11.5.4 HF2,…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.58%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
