Versions 10.0, 11.0 and 12.0 of the Trend Micro Deep Security Agent are vulnerable to an arbitrary file delete attack, which may lead to availability impact. Local OS access is required. Please note that only Windows agents are affected.

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
Deep_security Trendmicro 10.0 (including) 10.0 (including)
Deep_security Trendmicro 11.0 (including) 11.0 (including)
Deep_security Trendmicro 12.0 (including) 12.0 (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.
