# Onapsis Security Advisory 2022-0004: Missing Authentication check in SAP Focused Run (Simple Diagnostics Agent 1.0) ## Impact on Business Because the Simple Diagnostic Agent (SDA) handles several important configuration and critical credential information, a successful attack could lead to the control of the SDA, and therefore affect: * Integrity, by modifying the configuration. * Availability, by stopping the service. * Confidentiality and Scope changing, by decrypting all stored credentials. Then accessing the SAP Focused Run system as well as the SAP system managed by the SDA. ## Advisory Information - Public Release Date: 06/21/2022 - Security Advisory ID: ONAPSIS-2022-0004 - Researcher(s): Yvan Genuer ## Vulnerability Information - Vendor: SAP - Affected Components: - SIMPLE\_DIAGNOSTICS\_AGENT 1.0 (Check SAP Note 3145987 for detailed information on affected releases) - Vulnerability Class: CWE-306 - CVSS v3 score: 9.3 AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H - Risk Level: Critical - Assigned CVE: CVE-2022-24396 - Vendor patch Information: SAP Security NOTE 3145987 ## Affected Components Description SAP Focused Run is a spin-off from SAP Solution Manager concentrating on the specific needs of high volume system and application monitoring, alerting and analytics needs. (https://support.sap.com/en/alm/sap-focused-run/expert-portal/) ## Vulnerability Details Vulnerability 1: No authentication is required to interact with the Simple Diagnostic Agent http service on port 3005 by default. Therefore, unauthenticated attackers will have full access to either administrative or other privileged functionalities. Leveraging this access, they would be able to read, modify or delete sensitive information and configurations with sapadm OS user privileges. Vulnerability 2: A path traversal exists in the Simple Diagnostic Agent service listening, by default, on localhost port 3005. A local attacker, without particular privileges, can abuse this flaw in order to display the content of any OS directory which ```sapadm``` has access to. Leading to information disclosure of potentially sensitive data. ## Solution SAP has released SAP Note 3145987 which provide patched versions of the affected components. The patches can be downloaded from https://launchpad.support.sap.com/#/notes/3145987. 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 - 01/28/2022: Onapsis sends details to SAP - 02/02/2022: SAP provides internal ID - 03/08/2022: SAP releases SAP Note fixing the issue. - 06/21/2022: Advisory published. ## References - Onapsis blogpost: https://onapsis.com/blog/sap-security-patch-day-march-2022-sap-focused-run-affec ted-several-vulnerabilities - CVE Mitre: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-24396 - Vendor Patch: https://launchpad.support.sap.com/#/notes/3145987 ## About Onapsis Research Labs Onapsis Research Labs provides the industry analysis of key security issues that impact business-critical systems and applications.
