### Description

SAP Download Manager 2.1.142 and earlier generates an encryption key from a small key space on Windows and Mac systems, which allows context-dependent attackers to obtain sensitive configuration information by leveraging knowledge of a hardcoded key in the program code and a computer BIOS serial number, aka SAP Security Note 2282338.
