May 2022 notes

Summary and highlights of the month

The total number of notes/patches has decreased compared to last month. In addition to this decrease in the total number of notes, the number of Hot News also decreased, with 8 notes last month compared to 4 in May. On the other hand, it should be noted that the number of high criticality notes decreased from 7 to 2 this month. As usual, we will leave the medium and low scores unchecked this month, but we will give details of a total of 6 scores (all those with a CVSS of 7 or higher).

We have a total of 17 notes for the whole month, 18 less than last April (12 from Patch Tuesday, 8 new and 4 updates, being 21 less than last month).

We have 4 Hot News, 3 new and 1 update, in this month, which stand out for their high CVVS. We will also review in detail 2 of the total of 2 new high notes (those with CVSS greater than or equal to 7).

  • The most critical notes of the month (with CVSS 9.8) are 4 related to “Remote Code Execution vulnerability”.
  • The next in criticality (CVSS 8.3 and 7.8) are two critical scores, one for “Cross-Site Scripting (XSS) vulnerability in administration UI of SAP Webdispatcher and SAP Netweaver AS for ABAP and Java (ICM)” and the other for “Central Management Server Information Disclosure in Business Intelligence Update”.
  • The rest (11) are medium level, and we will not look at them in detail, although it is worth noting that there is more than one that affects SAP NetWeaver.
  • This month the most predominant types are “Remote Code Execution vulnerability” (4/17 and 4/12 in patch day) and “Cross-Site Scripting (XSS)” (3/17 and 3/17 in patch day).

In the graph (post May 2022 from SAP) we can see the classification of the May notes in addition to the evolution and classification of the last 5 previous months (only the notes of Sec. Tuesday / Patch Day – by SAP):

  • Remote Code Execution vulnerability associated with Spring Framework used in SAP Customer Profitability Analytics (3189635): Symptom: SAP Customer Profitability Analytics uses a version of Spring Framework which has Remote Code Execution vulnerability. Reason and Prerequisites: SAP Customer Profitability Analytics makes use of a version of the Spring framework that is vulnerable to Spring4Shell attacks. Solution: The Spring framework has been updated to a patched version, which isn’t vulnerable to Spring4Shell attacks. CVSS v3 Base Score: 9,8 / 10 (CVE-2022-22965).

SAP and the Onapsis Research Labs (ORL) found a high impact on a system’s confidentiality, integrity, and availability when exploiting the vulnerability. The only thing that prevents this vulnerability from being tagged with a higher CVSS is the fact that an attacker must entice a victim to log on to the administration UI using a browser and that the attack is highly complex. CVSS v3 Base Score: 8,3 / 10 (CVE-2022-27656).
  • Central Management Server Information Disclosure in Business Intelligence Update (2998510): This note patches a problem that exists during an upgrade of  SAP BusinessObjects Enterprise.
