SAP’s May 2020 Security Patch Day updates, which the company released on Tuesday, include a total of 18 Security Notes and 4 updates to previous Notes, with six of them rated Hot News.
The most important of the Notes addresses a code injection vulnerability in NetWeaver Application Server ABAP. Tracked as CVE-2020-6262 and featuring a CVSS score of 9.9, the issue exists because a remote-enabled function module that dynamically generates code fails to sufficiently validate input.
The bug could allow an attacker to take control of an ABAP system connected to a Solution Manager (SolMan) system. The flaw affects ABAP versions 2008_1_46C, 2008_1_620, 2008_1_640, 2008_1_700, 2008_1_710, and 740.
“Only the fact that an attacker needs a minimum level of authorizations to exploit this vulnerability has prevented it from receiving a CVSS of 10.0,” Onapsis, a firm that specializes in securing Oracle and SAP applications, explains.
Two other Hot News Notes deal with vulnerabilities in the Business Objects business intelligence platform. The first of them addresses a missing authentication check (CVE-2020-6242, CVSS score of 9.8), while the second patches deserialization of untrusted data (CVE-2020-6219, CVSS score of 9.1), but is an update to a Note released in April.
This month, SAP released another update to a Hot News Security Note released in April 2018, which includes security patches for Chromium browser controls in Business Client. The new update provides support for Chromium version 81.0.4044.92.
The remaining two Hot News Notes released this week address a code injection in the Backup Server of Adaptive Server Enterprise (CVE-2020-6248, CVSS score of 9.1), and an information disclosure bug in Adaptive Server Enterprise (ASE) Cockpit (CVE-2020-6252, CVSS score of 9).
SAP also released three High Priority Notes for SAP ASE, to fix an SQL injection flaw (CVE-2020-6241, CVSS score of 8.8), a code injection bug in the XP Server component (CVE-2020-6241, CVSS score of 8 – only affects installations on Windows platforms), and an SQL injection in Web Services (CVE-2020-6253, CVSS score of 7.2).
A fourth High Priority Note patches a code injection issue in Master Data Governance (MDG). Tracked as CVE-2020-6249, the vulnerability has a CVSS score of 7.7.
According to Onapsis, three other High Priority Notes should be added to the list, although they were not released on the May 2020 Security Patch Day. These include information disclosure flaws in Landscape Management and ABAP Server, and binary planting in Business Client.
The remaining 12 Notes released on the May 2020 Security Patch Day are assessed with a Medium Priority rating. They address missing authorization checks, Cross-Site Scripting (XSS), improper session management, denial of service, and other issues in Business Client, ASE, Business Objects Enterprise Threat Detection, MDG, Plant Connectivity, ABAP, and Identity Management.
If all the Notes that were released between the second Tuesday of last month and the second Tuesday of this month are counted, along with the updates to previously released Notes, SAP’s updates for May 2020 include a total of 29 security patches.
