MEDIUM 6.5EPSS 0.62%

Does this matter?

Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.

Description

The GUI component (aka PulseUI) in Pulse Secure Desktop Linux clients before PULSE5.2R9.2 and 5.3.x before PULSE5.3R4.2 does not perform strict SSL Certificate Validation. This can lead to the manipulation of the Pulse Connection set.
