AdminNeo can run attacker code in the admin browser via a rogue database server

If someone tricks you into connecting AdminNeo to a fake database server, that server can send back a specially crafted reply that makes your browser run code chosen by the attacker. This can happen without you logging in to anything.

How the attack works simplified

  1. 1Attacker sets up serverFake MySQL server returns crafted version string
  2. 2Admin connectsAdminNeo connects to the rogue database server
  3. 3Version string insertedUnescaped into a script tag with valid nonce
  4. 4Script runsCSP nonce lets injected code execute
  5. ResultAttacker runs code in the admin's browser

What happened

AdminNeo places the database server's version string unescaped inside a JavaScript script tag that has a valid CSP nonce, so a malicious version string can break out of the JavaScript context and execute arbitrary code, and the CSP does not block it.

Why it is dangerous: An attacker who controls a reachable MySQL server or can get an admin to connect to one can run scripts in the AdminNeo session, potentially taking over the admin's database tool and the data it can reach. Login CSRF can make this possible without authentication.

Are you affected?

You are affected if you run AdminNeo versions earlier than 5.5.1 and the admin can be made to connect to a database server the attacker controls or can reach.

Package / productAffected versionsFixed in
adminneo-org/adminneo · composer< 5.5.15.5.1

What to do

  1. Update AdminNeo (composer adminneo-org/adminneo) to version 5.5.1 or later
  2. Only connect AdminNeo to database servers you trust until the update is applied
  3. Log out of AdminNeo sessions and avoid using it while browsing other sites
