Platform dependent weakness.
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.

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
