How the attack works simplified

  1. 1Low-privileged accountAttacker starts with basic access
  2. 2Authorization flawMissing permission check is bypassed
  3. 3Code executionArbitrary code runs as current user
  4. ResultAttacker runs code on the system

What happened

Adobe Campaign Classic has an Incorrect Authorization flaw (missing or wrong permission checks) that allows arbitrary code execution in the context of the current user, with a changed scope.

Why it is dangerous: An attacker with only low-level access could run code on the affected system, potentially reaching beyond what their account should allow. Organizations running Adobe Campaign Classic are at risk.

Are you affected?

You are affected if you run Adobe Campaign Classic (ACC) with any low-privileged user accounts that can reach the application.

Adobe Campaign Classic (ACC) — specific versions not stated in the available material.

  1. Check the Adobe security bulletin for Adobe Campaign Classic and install the fixed version as soon as it is available
  2. Limit user accounts and access to Adobe Campaign Classic to only those who need it
  3. Monitor systems running Adobe Campaign Classic for unusual activity or unexpected processes
