SAP NetWeaver AS ABAP XSS (June 2021)

medium Nessus Plugin ID 150717
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote SAP NetWeaver server is affected by a Cross-Site Scripting vulnerability.

Description

A cross-site scripting (XSS) vulnerability exists in SAP NetWeaver Application Server ABAP due to improper encoding of user-supplied input. An authenticated, remote attacker can exploit this, to execute arbitrary script code in a user's browser session.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Apply the appropriate patch according to the vendor advisory.
