Published: 2023-03-14 · updated 2026-06-17

Description

Due to insufficient encoding of user input, SAP NetWeaver - versions 700, 701, 702, 731, 740, 750, allows an unauthenticated attacker to inject code that may expose sensitive data like user ID and password, which could lead to reflected Cross-Site scripting. These endpoints are normally exposed over the network and successful exploitation can partially impact confidentiality of the application.

Affected products

SAP_SE SAP NetWeaver: 700, 701, 702, 731, 740, 750
