Summary: PDS is providing the following communication to build awareness of a critical risk in Ivanti’s Pulse Connect Secure software.

On April 16, 2021 Ivanti released notice of an authentication bypass vulnerability which can allow an unauthenticated user to perform remote arbitrary file execution on the Pulse Connect Secure gateway. The CVE 2021-22893 has been assigned a score of 10, the highest criticality on the scale. The notice is available here: Pulse_Security_Advisories-SA44784

Ivanti has updated their advisory (April 19) with a workaround while a patch is being developed.
