Dell Display and Peripheral Manager (Windows) versions prior to 2.2 contain an Improper Link Resolution Before File Access (Link Following) vulnerability in the Installer and Service. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges
Weakness
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.
Potential Mitigations
- 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.
