CVE-2003-0646: Multiple buffer overflows in ActiveX controls used by Trend Micro HouseCall 5.5 and 5.7, and Damage Cleanup...

Security readout for executives and security teams

This is a legacy Trend Micro ActiveX vulnerability from 2003. If an old vulnerable control remains installed and can be invoked by a browser or related component, a remote attacker could potentially run code on the affected Windows system. Current business risk depends almost entirely on whether these obsolete components still exist in the environment. Likely exposure is limited to legacy Windows systems that still have vulnerable Trend Micro HouseCall 5.5/5.7 or Damage Cleanup Server 1.0 ActiveX controls installed or usable. Modern environments are less likely exposed unless old browser controls were retained during upgrades or migrations. Prioritize as a legacy exposure cleanup item. It is serious if present because code execution is possible, but urgency depends on finding vulnerable ActiveX controls in current assets. Start with inventory before assuming broad exposure. Mitigation focus: Inventory systems for Trend Micro HouseCall 5.5, 5.7, and Damage Cleanup Server 1.0 components.; Remove or disable obsolete Trend Micro ActiveX controls where no longer required.; Review Trend Micro solution 15274 for official vendor remediation guidance..
