SAP NetWeaver AS Java Multiple Vulnerabilities (April 2023)

high Nessus Plugin ID 174400

Language:

Synopsis

The remote SAP NetWeaver application server is affected by multiple vulnerabilities.

Description

SAP NetWeaver Application Server for Java is affected by multiple vulnerabilities, including the following:

- SAP NetWeaver AS Java for Deploy Service - version 7.5, does not perform any access control checks for functionalities that require user identity enabling an unauthenticated attacker to attach to an open interface and make use of an open naming and directory API to access a service which will enable them to access but not modify server settings and data with no effect on availability and integrity. (CVE-2023-24527)

- An unauthenticated attacker over the network can attach to an open interface exposed through JNDI by the User Defined Search (UDS) of SAP NetWeaver Process Integration (PI) - version 7.50 and make use of an open naming and directory API to access services which can be used to perform unauthorized operations affecting users and data across the entire system. This allows the attacker to have full read access to user data, make limited modifications to user data, and degrade the performance of the system, leading to a high impact on confidentiality and a limited impact on the availability and integrity of the application. (CVE-2022-41272)

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.
