# Onapsis Security Advisory 2021-0011: Missing authorization check in SolMan End-User Experience Monitoring ## Impact on Business Any authenticated user of the Solution Manager is able to craft/upload and execute EEM scripts on the SMDAgents affecting its Integrity, Confidentiality and Availability. ## Advisory Information - Public Release Date: 06/14/2021 - Security Advisory ID: ONAPSIS-2021-0011 - Researchers: Gonzalo Roisman, Pablo Artuso ## Vulnerability Information - Vendor: SAP - Affected Components: - SAP Solution Manager 7.2 (Check SAP Note #2983204 for detailed information on affected releases) - Vulnerability Class: [CWE-862]: Missing Authorization - CVSS v3 score: 7.6 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L) - Risk Level: High - Assigned CVE: CVE-2020-26830 - Vendor patch Information: SAP Security NOTE #2983204 ## Affected Components Description SAP SolMan 7.2 introduces a bunch of web services which run on top of the SAP Java NetWeaver stack. The affected versions have a vulnerable web service exposed. Affected components: * Solman 7.20 * Solman Java Stack NW 7.5 * LM-SERVICE: 1000.7.20.9.14.20200731160700 (Check SAP Note #2983204 for detailed information on affected releases) ## Vulnerability Details The main objective of the End-user Enterprise Monitoring (EEM) app is to upload scripts which will mimic user actions in order to be able to automatically perform different kinds of tests. This process is intended to be carried out by SAP administrators who want to monitor their instances. However, due to a lack of authorization check, any valid user from the Solution Manager is able to fully utilize this application. In other words, any valid user is able to craft its own script, upload it and force its execution by an SMD Agent. Some tasks that can be carried out are: * Execution of arbitrary HTTP requests from the SMD Agent. * Disclosure of sensitive content. * Resource consumption of specific services. ## Solution SAP has released SAP Note #2983204 which provide patched versions of the affected components. The patches can be downloaded fromhttps://launchpad.support.sap.com/#/notes/2983204. Onapsis strongly recommends SAP customers to download the related security fixes and apply them to the affected components in order to reduce business risks. ## Report Timeline - 10/05/2020 - Onapsis sends details to SAP - 10/05/2020 - SAP provides tracking id. - 10/12/2020 - SAP provides update: "Fix in progress" - 11/09/2020 - SAP provides update: "In process" - 11/30/2020 - SAP proposes to split the original submission into two different vulnerabilities. - 12/02/2020 - Onapsis agrees to split the submission. - 12/08/2020 - SAP releases note. ## References - Onapsis blogpost: https://onapsis.com/blog/sap-security-notes-december-2020 - CVE Mitre: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-26830 - Vendor Patch: https://launchpad.support.sap.com/#/notes/2983204. ## About Onapsis Research Labs Onapsis Research Labs provides the industry analysis of key security issues that impact business-critical systems and applications.
