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:

- Due to missing authentication check, SAP NetWeaver AS for Java - version 7.50, allows an unauthenticated attacker to attach to an open interface and make use of an open naming and directory API to access services which can be used to perform unauthorized operations affecting users and services across systems. On a successful exploitation, the attacker can read and modify some sensitive information but can also be used to lock up any element or operation of the system making that it unresponsive or unavailable.(CVE-2023-23857)

- SAP NetWeaver Application Server Java for Classload Service - version 7.50, does not perform any authentication checks for functionalities that require user identity, resulting in escalation of privileges. This failure has a low impact on confidentiality of the data such that an unassigned user can read non-sensitive server data. (CVE-2023-24526)

- Cache Management Service in SAP NetWeaver Application Server for Java - version 7.50, does not perform any authentication checks for functionalities that require user identity. (CVE-2023-26460)

- SAP NetWeaver AS Java (Object Analyzing Service) - version 7.50, does not perform necessary authorization checks, allowing 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., resulting in escalation of privileges. (CVE-2023-27268)

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.
