CVE-2019-4603Network attack vector

Keyword authorship spoofing via REST API

Published Apr 8, 2020 · Updated Sep 17, 2024

Authorization flaw in IBM Engineering Test Management 6.0.2, 6.0.6, and 6.0.6.1 allows remote authenticated users to falsify keyword authorship. IBM identifies the keyword-creation REST API as the locus but has not disclosed the request field or missing authorization check that permits false creator attribution. Any authenticated account able to create keywords can cause records to appear as though another user created them, affecting record integrity without reported disclosure or service interruption.
