EPICS Base: network message flaws can crash or expose control systems

EPICS is software used to run lab and industrial control equipment. Specially crafted network messages can crash it or make it read memory it should not, and in some cases an attacker may be able to run their own code.

How the attack works simplified

  1. 1Attacker sends messageCrafted network request to EPICS service
  2. 2Length check failsOverflow gives wrong buffer size
  3. 3Memory overwrittenOut-of-bounds read or write occurs
  4. 4Crash or code runDenial of service or possible code execution
  5. ResultControl application crashes or is compromised

What happened

Multiple flaws in EPICS Base release 7.0.10 and prior, including integer overflows and insufficient length validation in network message processing, can cause memory corruption, out-of-bounds reads and writes, and denial of service.

Why it is dangerous: An attacker who can reach the network service can crash critical control applications or read adjacent memory, and potentially execute code, affecting facilities that rely on EPICS (e.g. Critical Manufacturing sector).

Are you affected?

You are affected if you run EPICS Base release 7.0.10 or earlier on a system reachable over the network.

EPICS Base release 7.0.10 and prior

What to do

  1. Update EPICS Base to release 7.0.11 or later
  2. If you cannot update right away, restrict network access to EPICS services to trusted hosts only
  3. Contact the EPICS Controls team for guidance: https://epics-controls.org/support/
