tooljet/tooljet: Authorization Bypass Through User-Controlled Key

Published Updated By the CyberSecBulletin desk

CVE-2022-3019 is a high-severity authorization bypass through user-controlled key vulnerability in tooljet/tooljet from ToolJet, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 1.23.0 as the first without the flaw, so updating tooljet/tooljet to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1% chance of exploitation within 30 days, higher than 63% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update tooljet/tooljet to 1.23.0 or a later version.
  2. Update Tooljet to 1.23.0 or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  4. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

The forgot password token basically just makes us capable of taking over the account of whoever comment in an app that we can see (bruteforcing comment id's might also be an option but I wouldn't count on it, since it would take a long time to find a valid one).

The underlying weakness: Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

How developers prevent this class of flaw

  • For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
  • Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
  • Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
