Name of the Vulnerable Software and Affected Versions JetBrains TeamCity versions prior to 2021.2

Description The issue is related to a Time-of-check/Time-of-use (TOCTOU) race-condition attack in agent registration via XML-RPC. This type of attack occurs when there is a delay between the time of check and the time of use of a resource, allowing an attacker to exploit the window of opportunity.

Recommendations For versions prior to 2021.2, update to version 2021.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the XML-RPC agent registration functionality until a patch is applied.
