Improper Link Resolution Before File Access

CWE-59

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.

We track 491 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 8.0. 25 have been exploited in real attacks.

How this weakness is prevented

  • Architecture and Design: 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.
