CVE-2020-4312Network attack vector

Authenticated disclosure of cached web content

Published May 13, 2020 · Updated Sep 16, 2024

Information disclosure in IBM Sterling B2B Integrator 5.2.0.0 through 6.0.3.1 allows remote authenticated users to read sensitive cached data. IBM identifies the exposed locus only as a cached web page and has not published the cache-control or authorization failure that makes the content readable. Access requires a valid account and a network request to the web interface; the documented consequence is limited to disclosure of cached information.
