Official description

Vulnerabilities in the Drive Composer allow a low privileged attacker to create and write to a file anywhere on the file system as SYSTEM with arbitrary content as long as the file does not already exist. The Drive Composer installer file allows a low-privileged user to run a "repair" operation on the product.

The underlying weakness: Improper Link Resolution Before File Access

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

How developers prevent this class of flaw

  • Follow the principle of least privilege when assigning access rights to entities in a software system. Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
