Arbitrary file deletion exists on Peplink Balance 305, 380, 580, 710, 1350, and 2500 devices with firmware before fw-b305hw2_380hw6_580hw2_710hw3_1350hw2_2500-7.0.1-build2093.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.71%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
