CVE-2023-35018Network attack vector

Arbitrary file write via improper upload validation

Published Oct 15, 2023 · Updated Sep 16, 2024

Unrestricted file upload in IBM Security Verify Governance 10.0 allows remote authenticated users with high privileges to write arbitrary files. The upload path accepts files without validating whether their type is dangerous; IBM has not identified the endpoint, function, or destination path. High privileges and a high-complexity network request are required, and the published impact is limited to low confidentiality and integrity loss without a service interruption.
