CVE-2021-22030Network attack vector

Credential disclosure via sensitive statement logging

Published Nov 19, 2021 · Updated Aug 3, 2024

Sensitive-data logging in Greenplum Database 5.28.x before 5.28.14 and 6.x before 6.17.0 allows local users to read credentials. Execution of certain database statements writes credential material into database log entries; the vendor has not identified the statement types or logging locus. Exploitation requires access to database logs and exposes stored user credentials without altering data or interrupting service.
