CVE-2021-29767Network attack vector

Sensitive information disclosure via verbose browser errors

Published Jul 26, 2021 · Updated Sep 17, 2024

Information disclosure in IBM i2 Analyst's Notebook Premium 9.2.0 through 9.2.2 allows remote attackers to read sensitive error details. The HTTP error-handling path returns detailed technical messages in the browser instead of limiting responses to nonsensitive error text. No authentication or user interaction is required, and the exposed details support follow-on attacks without directly altering data or service availability.
