Dll Hijacking in SAP Financial Consolidation, SAP security note 2172049

Description

An unwanted dll may be loaded by SAP Financial Consolidation.

SAP Financial Consolidation uses English as the default language and loads the English dll resource to retrieve default localized strings. The corresponding dll will be missing in case English is not installed.

The product tries to load the missing dll in all paths configured in the PATH environment variable. An attacker with access to one of the referenced paths could replace the existing dll with a malicious dll with the same name, which in turn would load this malicious dll for the victim users.
