CVE-2020-4357Network attack vector

Sensitive information disclosure via verbose GUI errors

Published May 27, 2020 · Updated Sep 17, 2024

Information disclosure in IBM Spectrum Scale GUI 5.0.0.0 through 5.0.4.4 allows remote authenticated users to read sensitive data. The GUI returns detailed technical error messages in the browser that include sensitive information, but IBM has not identified the affected request handler or disclosed which error data is exposed. Access to the network-facing GUI with low privileges is required, and the disclosed details can support further attacks without directly changing data or interrupting service.
