SAP Patch Tuesday overview for July 2023 

A review, best practices and tips and tricks for this months’ SAP Security patches – Fixing SAP vulnerabilities. 


A new month, a new SAP Security Patch Tuesday! The 2nd Tuesday in the month where SAP releases patches to fix vulnerabilities in SAP products. Either being discovered by SAP internally, or by external researchers such as Protect4S’ own researchers. All trying to improve SAP’s product security and have SAP customers run their SAP systems more secure.  

As always, customers should assess the list of released SAP Security notes and apply them where applicable according to their SAP Vulnerability Management process and procedures. This month, counting from the last Patch Tuesday, there are a total of 16 new and 2 updated SAP Security notes. 2 of these have the highest HotNews rating (CVSS 9 or higher). See a summary below for the highest rated notes.  

  • SAP Business Client: Note 2622660 is a regularly returning SAP security note concerning Google Chromium and is relevant for customers that have deployed SAP Business Client. In this update of July 2023 there is a relevant update with patches concerned having a CVSS score of 9.6. It is stated by Google that exploits exist for the mentioned vulnerabilities so do consider these patches carefully! See also our previous blog about this particular note. 
  • IS-OIL: Note 3350297 describes an OS command injection vulnerability that can give extensive control to an attacker for this industry solution. CVSS is 9.1. Note there is no workaround available and that patching may require manual steps. See FAQ note 3349318 for more information. 
  • SAP NetWeaver – BI CONT: Note 3331376 describes a Directory Traversal vulnerability with CVSS 8.7. Simply apply the relevant correction instruction or support package to solve this. 
  • SAP Web Dispatcher / ICM: Note 3233899 and 3340735 both describe vulnerabilities (CVSS 8.7 and 7.7) that are relevant for a wide array of configurations. That is: stand-alone web dispatcher installations as well as integrated setups in the ASCS, SAP HANA and the ICM of an SAP NetWeaver ABAP stack. A workaround is possible by disabling protocol HTTP/2 because only this version is affected. Review the dependencies carefully and apply the updates for a secure configuration! 
  • SAP Diagnostics Agent: Note 3352058 and 3348145 both describe vulnerabilities with a CVSS score of 7.2. Patches are available, note that this requires patching of the LM_SERVICE component of the related SAP Solution Manager system. 

At the moment of writing, there are no further public exploits available to our knowledge for the above-mentioned notes. A breakdown by priority can be found below:

For organisations using SAP software it is important to have a process and procedures in place that ensures that every month the SAP Security notes are reviewed, assessed for relevance and risk and that patches are applied. The Protect4S Vulnerability Management solution supports this process by automatically scanning your SAP landscape for missing SAP Security notes and apply them in an automated way for ABAP systems (for the patches with automatic correction instructions). A full overview of this months’ SAP Security notes can be found below (These are new and updated notes released after last months’ patch Tuesday):
