Trend Micro Maximum Security 2022 is vulnerable to a link following vulnerability that could allow a low privileged local user to manipulate the products secure erase feature to delete arbitrary files.

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
Maximum_security_2022 Trendmicro 17.7 (including) 17.7 (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.
