Restricted information disclosure via malicious server name
Published Jun 9, 2021 · Updated Aug 3, 2024
Information disclosure in SAP NetWeaver AS Java UserAdmin 7.11 through 7.50 allows remote authenticated users to read restricted data. UserAdmin accepts an attacker-supplied server name and uses it while returning information outside the caller's authorized scope; SAP has not published the responsible handler or validation failure. Exploitation requires high-privileged network access, and the published record reports disclosure without service interruption.
