CVE-2023-31181Network attack vector

Unauthenticated file read via path traversal

Published May 8, 2023 · Updated Jan 29, 2025

Path traversal in Wjj Software InnoKB Server 2.2.1 through 2.2.2 allows remote attackers to read server files via network requests. The CNA and vendor materials do not identify the request path, parameter, or filesystem operation that fails to confine the requested pathname. No authentication or user interaction is required, and the published impact is limited to confidentiality.
