SAP Security Patches August 2023

Let’s delve into the details of the SAP Security Patch Day for August 2023. First off, let’s take a look at the highest-priority security patches. Within the SAP vocabulary, these are referred to as ‘Hot News,’ which encompass CVSS scores ranging from 9.1 to 10.

Starting with the Hot News

Two Hot News Security Patches are included in today’s release, one (SNote 3341460) of which is new and contains a collective fix of multiple vulnerabilities residing in the SAP PowerDesigner product, more specific in the SAP PowerDesign Proxy. The second contains an update (meanwhile in version 19) of SNote 3350297 that resolve a OS Command Injection vulnerability in SAP ECC and SAP/S4HANA (IS-OIL). This correction should only concern IS-OIL customers. The recent update contains more detailed information about prerequisites and important remarks regarding IS-OIL switches that wrongly used, can cause harm to your system.

Focus on SAP BusinessObjects, SAP Business One, SAP Message Server and SAP Commerce, with High Priority

Five main system types received high priority corrections, hence require our attention as we review the SAP Security Patches released in August ’23.

Focus on SAP BusinessObjects

The SAP BusinessObjects has been the recipient of three corrections, involving patch 3312047. This patch addresses a Denial of Service (DoS) vulnerability stemming from the utilization of a vulnerable version of Commons FileUpload within the SAP BusinessObjects Business Intelligence Platform (CMC). The patch title indicates that the SAP component has resolved a vulnerability resulting from the usage of the ‘commons-fileupload’ component, which is described in CVE-2023-24998.

Additionally, today marked the release of patch 3317710 – [CVE-2023-37490], addressing a Binary Hijack vulnerability within the SAP BusinessObjects Business Intelligence Suite (installer), which has been assigned a CVSS score of 7.6. This issue is rooted in the installer routine, potentially granting an unauthenticated attacker with network access the ability to overwrite or manipulate executables utilized during the installation process.

Our experts have identified various attack scenarios, including the potential implementation of backdoors or ransomware. It’s important to note that exploitation of this vulnerability can be challenging to detect for clients. Therefore, we strongly recommend the prompt implementation of this corrective patch.

Tagged with a priority “Medium” comes another correction for SAP BusinessObject with SNote 3312586 and a CVSS of 4.4 addressing [CVE-2023-39440] Information Disclosure vulnerability in SAP BusinessObjects Business Intelligence Platform.

Focus on SAP Message Server

The SAP Message Server is an integral part of the ABAP Server Central Services Instance (ASCS instance). This critical component, present in all SAP installations, has received a High priority update with SNote 3344295. This update addresses an SAP vulnerability related to Improper Authorization checks. The risk associated with unpatched systems is that the Access Control List (ACL) can be bypassed under certain conditions.

There are several prerequisites that must be met, including SAP Message Server versions ranging from 7.22 to 7.77. We intentionally do not provide extensive details on this public page. Instead, the relevant information is accessible exclusively to registered SAP customers. The correction should be prioritized based on our experts’ recommendations. It’s important to note that implementing this update might require downtime. A workaround has been outlined within the note, which can help bridge the gap between the present and full implementation to mitigate the risk of exploitation.

Focus on SAP Business One

This product has received three updates, with two of them being tagged as High priority. SNote 3337797 addresses a SQL Injection vulnerability in SAP Business One (B1i Layer), mitigating CVE-2023-33993. Additionally, SNote 3358300 resolves a Cross-Site Scripting (XSS) vulnerability with a CVSS score of 7.6.

Both of these patches are straightforward and require no further explanation. While applying the patches, be sure not to overlook SNote 3333616, which has a severity level of Medium. You can find these patches on the SAP ONE Support Launchpad – Software Center.

Focus on SAP Power Designer

Next to Hot News SNote 3341460 which contains a collective fix of multiple vulnerabilities residing in the SAP PowerDesigner product, also the SNote 3341599 which High priority has been released to resolve a Code Injection vulnerability in SAP PowerDesigner.

And more, Affected System Types

While you can find the summary sorted by severity in the list below, in this section we provide structured insight in which system types have received a security update. Following our experts analysis we find correction for the SAP ABAP and ABAP Platform (5), SAP Business One (3), SAP Business Objects (3), SAP Commerce & Commerce Cloud (2), SAP Host Agent (1), SAP Message Server (1), SAP PowerDesigner(2), SAP PI (1) and SAPUI5 (1).

Overall a rather wide scope of affected system types have received a security update in the SAP Security Patch Day of this month. For customers this could means additional effort since the various components can not be patched following the same procedure.
