Critical Perimeter Alert: The Reality of Chained Zero-Clicks

Today's CISA KEV expansion highlights a massive reality check for enterprise defense. Look at the Ivanti Connect Secure chain (CVE-2026-104935):

1. Auth bypass via an edge script (welcome.cgi)

2. Arbitrary file-write via an internal component (wu.cgi)

3. Root privilege escalation through a background broker (dsinvoked)

The Problem: Threat actors are executing specialized Python streaming logic completely in-memory (exec()) to completely bypass traditional disk-based EDR/SIEM logging footprint checks.

Perimeter verification can no longer just look at state changes or file drops. If your gate doesn't intercept the transaction deterministically at Layer Zero before execution privileges are brokered, the environment is already compromised.

How is your SOC handling in-memory RCE detection on edge appliances? Drop your thoughts below. 👇
