SAP Patches High-Risk Vulnerabilities in NetWeaver

German software maker SAP has released 12 new security notes as part of its July 2021 security patch day, as well as updates for three previously released security notes.

German software maker SAP has released 12 new security notes as part of its July 2021 security patch day, as well as updates for three previously released security notes.

The most important of the new security notes deal with two high-severity vulnerabilities in NetWeaver. The first is a missing authorization check (CVE-2021-33671, CVSS score of 7.6), while the second is a denial of service (CVE-2021-33670, CVSS score of 7.5).

The first flaw affects SAP NetWeaver Guided Procedures (SAP GP), a component of the Composite Application Framework (CAF) that provides role-based access to multiple backend systems. The missing authorization was identified in the central administration tool for GP and could lead to unauthorized access to and manipulation of data.

The second vulnerability affects SAP NetWeaver AS for Java (Http Service) and exists because HTTP requests are not properly validated when monitoring data is stored. Thus, an attacker able to manipulate HTTP requests could exhaust system resources, causing a denial of service condition.

SAP also released nine new security notes dealing with medium severity vulnerabilities in CRM ABAP, NetWeaver AS ABAP and ABAP Platform, Lumira Server, Web Dispatcher and Internet Communication Manager, NetWeaver AS for Java (Enterprise Portal), Business Objects Web Intelligence (BI Launchpad), and 3D Visual Enterprise Viewer; and one security notes for a low-severity bug in NetWeaver AS for JAVA (Administrator).

Additionally, the company released updates for two Hot News security notes: one dealing with the security updates for the Chromium browser in SAP Business Client (CVSS score 10) and another for an improper authentication flaw in NetWeaver ABAP Server and ABAP Platform (CVSS score of 9) that was initially addressed in June 2021.

A third updated security note deals with a medium severity potential XML External Entity (XXE) vulnerability in SAP Process Integration (ESR Java Mappings).
