CVE-2023-32454

DUP framework version 4.9.4.36 and prior contains insecure operation on Windows junction/Mount point vulnerability. A local malicious standard user could exploit the vulnerability to create arbitrary files, leading to denial of service

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.

Affected Software

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.
