CVE-2023-4984Public exploitNetwork attack vector

Authenticated credential disclosure via plaintext password storage

Published Sep 15, 2023 · Updated Aug 2, 2024

Plaintext credential storage in DiDi KnowSearch 0.3.1.2 and 0.3.2 allows remote authenticated users to read Elasticsearch account passwords. The published record identifies processing at /api/es/admin/v3/security/user/1 but does not disclose which function or persistence operation stores the password in plaintext. A low-privileged network session is required, and the reported consequence is limited to credential disclosure with no integrity or availability impact.
