Improper link resolution before file access (Link Following) issue exists in iPrint&Scan Desktop for Windows versions 11.0.0 and earlier. A symlink attack by a malicious user may cause a Denial-of-service (DoS) condition on the PC.

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

Name Vendor Start Version End Version
Iprint&scan Brother * 11.0.0 (including)

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.
