Specific F5 BIG-IP platforms with Cavium Nitrox FIPS HSM cards generate a deterministic password for the Crypto User account.  The predictable nature of the password allows an authenticated user with TMSH access to the BIG-IP system, or anyone with physical access to the FIPS HSM, the information required to generate the correct password.  On vCMP systems, all Guests share the same deterministic password, allowing those with TMSH access on one Guest to access keys of a different Guest.

The following BIG-IP hardware platforms are affected: 10350v-F, i5820-DF, i7820-DF, i15820-DF, 5250v-F, 7200v-F, 10200v-F, 6900-F, 8900-F, 11000-F, and 11050-F.

The BIG-IP rSeries r5920-DF and r10920-DF are not affected, nor does the issue affect software FIPS implementations or network HSM configurations.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

On BIG-IP versions 17.0.x before 17.0.0.2, 16.1.x before 16.1.3.3, 15.1.x before 15.1.8.1, 14.1.x before 14.1.5.3, and all version of 13.1.x, when a DNS profile with the Rapid Response Mode setting enabled is configured on a virtual server with hardware SYN cookies enabled, undisclosed requests cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Platform dependent weakness. This issue only impacts iSeries platforms. On these platforms, in BIG-IP (LTM, AAM, AFM, Analytics, APM, ASM, DNS, Edge Gateway, FPS, GTM, Link Controller, PEM, WebAccelerator) versions 14.0.0-14.1.0.1, 13.0.0-13.1.1.3, and 12.1.1 HF2-12.1.4, the secureKeyCapable attribute was not set which causes secure vault to not use the F5 hardware support to store the unit key. Instead the unit key is stored in plaintext on disk as would be the case for Z100 systems. Additionally this causes the unit key to be stored in UCS files taken on these platforms.
