Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. In Github.com/runatlantis/atlantis, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The package github.com/runatlantis/atlantis/server/controllers/events before 0.19.7 is vulnerable to Timing Attack in the webhook event validator code, which does not use a constant-time comparison function to validate the webhook secret. It can allow an attacker to recover this secret as an attacker and then forge webhook events.
