How the attack works simplified

  1. 1Low-privileged userHolds a basic ACC account
  2. 2Crafted inputMalicious data sent to ACC
  3. 3SQL injectionInput executed as database commands
  4. 4Code executionAttacker runs code as current user
  5. ResultAttacker runs arbitrary code on the server

What happened

Adobe Campaign Classic (ACC) has an SQL injection vulnerability (CWE-89) where untrusted input reaches SQL commands without proper neutralization, enabling arbitrary code execution in the context of the current user, with scope changed.

Why it is dangerous: A low-privileged attacker could run arbitrary code, potentially reaching data and systems beyond what their account should allow, with critical severity (CVSS 9.9).

Are you affected?

You are affected if you run Adobe Campaign Classic (ACC) with a vulnerable version and users with low-privileged access can reach it.

What to do

  1. Check Adobe's security bulletin for ACC and identify the patched version for your release line
  2. Update Adobe Campaign Classic to the fixed version as soon as it is available
  3. Restrict low-privileged account access to ACC until patched
  4. Review logs for unusual SQL errors or unexpected commands
