CVE-2024-36378Network attack vector

Unauthenticated service interruption via incorrect auth tokens

Published May 29, 2024 · Updated Aug 2, 2024

Resource exhaustion in JetBrains TeamCity before 2024.03.2 allows remote attackers to interrupt the server with incorrect auth tokens. JetBrains has not disclosed which token-processing component allocates resources without adequate limits or how malformed tokens trigger exhaustion. Network access to the TeamCity server is sufficient; the documented effect is service interruption without confidentiality or integrity impact.
