CVE-2024-31139Network attack vector

Authenticated data disclosure and service interruption via XXE

Published Mar 28, 2024 · Updated Aug 2, 2024

XXE in JetBrains TeamCity's Maven build-step detector before 2024.03 allows remote authenticated users to read data or interrupt service. The detector permits XML external entity processing, but JetBrains has not disclosed the parser, input path, or exact unsafe operation. Exploitation requires high privileges and high-complexity conditions; published impacts are limited to confidentiality and availability.
