SAP this week released its monthly set of security patches to address just three vulnerabilities in its products, all three rated Medium severity.

In addition to the three security notes, the January 2018 SAP Security Patch Day includes four updates to previously released security notes. These too had a Medium severity rating, the company said.

The most severe of the patches were updates to a security note released in October 2014, which addressed a code injection bug in Knowledge Provider. The issue is tracked as CVE-2018-2363 and features a CVSS score of 6.5.

“Depending on the code, attackers can inject and run their own code, obtain additional information that should not be displayed, change and delete data, modify the output of the system, create new users with higher privileges, control the behavior of the system, or escalate privileges by executing malicious code or even perform a DOS attack,” ERPScan, a company that specializes in securing SAP and Oracle products, explains.

SAP also released an update to a security note released in December 2017, addressing CVE-2017-16690, a DLL preload attack possible on NwSapSetup and Installation self-extracting program for SAP Plant Connectivity (CVSS score 5.0).

Newly resolved issues include CVE-2018-2361, an Improper Role Authorizations in SAP Solution Manager 7.2 (CVSS score 6.3), CVE-2018-2360, Missing Authentication check in Startup Service (CVSS score 5.8), and CVE-2018-2362, Information Disclosure in Startup Service in SAP HANA (CVSS score 5.3).

By exploiting CVE-2018-2360, an attacker could access a service “without any authorization procedures and use service functionality that has restricted access. This can lead to an information disclosure, privilege escalation and other attacks,” ERPScan reveals.

CVE-2018-2361’s exploitation could provide an attacker with the possibility to edit all tables on the server, which could result in data compromise, the company continues.

ERPScan, which considers the code injection security note updates as a single patch, says that 10 SAP Security Notes (5 SAP Security Patch Day Notes and 5 Support Package Notes) were closed with the January 2018 SAP Security Patch Day. 3 were updates to previous security notes and 5 were released after the second Tuesday of the previous month and before the second Tuesday of this month.
