What happened

Ivanti Connect Secure 22.8R2.4 has a flaw where the dsinvoked broker wrongly trusts DSCache configuration data, allowing privilege escalation to root. Attackers are chaining it with other Ivanti flaws.

Why it is dangerous: An attacker who gets root can control the VPN appliance, reach internal networks, and potentially read or change data. Organizations running internet-facing Ivanti Connect Secure are most at risk.

Are you affected?

You are affected if you run Ivanti Connect Secure version 22.8R2.4, as named in the advisory; other versions are not stated in the material.

What to do

  1. Apply the mitigations listed in Ivanti's vendor instructions
  2. Check whether the appliance was compromised, following CISA's Forensics Triage Requirements if you are a federal agency
  3. Reduce internet exposure of the appliance and review who holds local accounts
  4. If mitigations are unavailable, discontinue use of the product per CISA guidance
