Advisory

SAP takes the security of its vast product portfolio very seriously and thus releases security fixes for vulnerabilities reported by external researchers and their customers every second Tuesday of the month.

SAP Note 2695776 was released on 14.01.2020 and deals with "Missing Authorization Check in SAP Mobile Platform Native SDK, Android" within SAP Mobile Platform. We advice you to follow the instructions, to resolve missing authorization check with a high potential for exploitation in component MOB-SDK-ODP.

According to SAP Security Advisory team a workaround exists. It is advisable to implement the correction as project.

Risk specification

By default applications useing the SAP Mobile Platform Native SDK does not properly set nessecary permissions and thereby allow attackers to obtains sensitive data.

Solution

The SDK Library now includes a default signature permission, so that by default only applications sihned with the same developer key are able to communicate.  And the good news are: a workaround exists, too! This was suggested by the SAP security experts: "If permissions are defined by the application itself rather than relying on the default, the application may not be vulnerable."

The advisory is valid for

  • SMP_NATIVE_SDK 3.1
