CVE-2023-45860Network attack vector

Authenticated file disclosure via unchecked SQL field resolution

Published Feb 16, 2024 · Updated Nov 6, 2024

Authorization bypass in Hazelcast 5.1.7 and earlier, 5.2.0 through 5.2.4, and 5.3.0 through 5.3.4 allows remote authenticated users to read files. SqlConnector.resolveAndValidateFields derives CSV field names from metadata and a sample without checking the file-read permissions required for that operation, while ReadFilesP previously permitted an unsecured DAG. A low-privilege client able to submit SQL or Jet work can disclose filesystem data readable by a cluster member; no data modification or service interruption is reported.
