JetBrains TeamCity before 2021.2 was vulnerable to a Time-of-check/Time-of-use (TOCTOU) race-condition attack in agent registration via XML-RPC.
The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
