How the attack works simplified

  1. 1Attacker crafts linkMalicious URL or compromised web page
  2. 2User visits linkVictim must interact with the page
  3. 3Code injectedAdobe Connect generates attacker code
  4. 4Code runs as userRuns with the victim's current privileges
  5. ResultAttacker runs code as the victim

What happened

Adobe Connect contains an Improper Control of Generation of Code (Code Injection) vulnerability (CWE-94) that can lead to arbitrary code execution in the context of the current user, with changed scope; triggered via a malicious URL or compromised web page.

Why it is dangerous: Successful exploitation runs attacker code with the victim's privileges and can reach beyond the application's own boundaries, putting users who open malicious links at risk.

Are you affected?

You are affected if you run Adobe Connect and users open links or web pages that an attacker could have crafted or compromised.
