CVE-2024-31140Network attack vector

Arbitrary file deletion via tool installation

Published Mar 28, 2024 · Updated Aug 2, 2024

Improper input validation in JetBrains TeamCity before 2024.03 allows remote authenticated users with server-admin rights to delete server files. The tool-installation path accepts administrator-supplied tool content that can remove files outside the intended tool area; JetBrains has not disclosed the exact validation error. Exploitation requires a server administrator and affects file integrity; no confidentiality or service-interruption impact is reported.
