CVE-2021-27599Network attack vector

Authenticated information disclosure via insecure cookies

Published Apr 14, 2021 · Updated Aug 3, 2024

Information disclosure in SAP Process Integration 7.10, 7.30, 7.31, 7.40, and 7.50 allows remote authenticated users to read restricted data. The Integration Builder framework does not consistently enforce the Secure and HttpOnly attributes on session cookies, weakening protection for authenticated sessions. Low-privileged network access is required, and the published impact is limited to confidentiality; SAP has not identified the exact request or data exposed.
