Detailsinfo

A vulnerability, which was classified as problematic, was found in SAP NW AS Java UME User Mapping ENGINEAPI 7.50/SERVERCORE 7.50/UMEADMIN 7.50. This affects an unknown code block of the component User Management Engine. The manipulation with an unknown input leads to a inadequate encryption vulnerability. CWE is classifying the issue as CWE-326. The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required. This is going to have an impact on confidentiality. The summary by CVE is:

The User Management Engine (UME) in NetWeaver Application Server for Java (NW AS Java) utilizes an obsolete cryptographic algorithm for encrypting User Mapping data. This weakness could allow an attacker with high-privileged access to exploit the vulnerability under specific conditions potentially leading to partial disclosure of sensitive information.This has low impact on confidentiality with no impact on integrity and availability of the application.

It is possible to read the advisory at me.sap.com. This vulnerability is uniquely identified as CVE-2026-0510 since 12/09/2025. The exploitability is told to be difficult.
