How the attack works simplified

  1. 1Privileged attackerHas high-privilege ACC account
  2. 2Crafted inputInjects SQL commands into a query
  3. 3SQL executedApplication runs the injected query
  4. 4Code executionAttacker runs code as current user
  5. ResultAttacker runs code on the server

What happened

Adobe Campaign Classic (ACC) has an SQL injection vulnerability (CWE-89) that can result in arbitrary code execution in the context of the current user. Scope is changed and no user interaction is required.

Why it is dangerous: An attacker who already holds high privileges could run arbitrary code, potentially reaching beyond the application itself. Organizations running Adobe Campaign Classic and their marketing data are at risk.

Are you affected?

You are affected if you run Adobe Campaign Classic (ACC) with the affected versions and have accounts with high privileges that could be misused.

Adobe Campaign Classic (ACC) — affected versions not specified in the material.

What to do

  1. Check Adobe's security bulletin for ACC and identify the patched version
  2. Apply the Adobe Campaign Classic update as soon as it is available
  3. Limit high-privilege accounts to only those who truly need them
  4. Review database and application logs for unusual SQL queries
