CVE-2001-0678: A buffer overflow in reggo.dll file used by Trend Micro InterScan VirusWall prior to 3.51 build 1349 for Wi...

Security readout for executives and security teams

CVE-2001-0678 is a legacy local code-execution flaw in Trend Micro InterScan components. A logged-in local attacker could abuse a buffer overflow in reggo.dll to run arbitrary code. Business urgency depends on whether these very old products still exist in the environment. Exposure is most likely limited to legacy Windows NT-era systems running the named Trend Micro InterScan products. Modern environments are unlikely to be affected unless old appliances, lab systems, or unsupported servers remain operational. Prioritize discovery rather than emergency response unless affected legacy systems are found. If present on production infrastructure, remediation should be scheduled promptly because local code execution in security software can undermine host trust. Mitigation focus: Inventory for Trend Micro InterScan VirusWall and InterScan WebManager installations.; Upgrade InterScan VirusWall to 3.51 build 1349 or later where applicable.; For InterScan WebManager 1.2, check archived Trend Micro guidance for supported remediation..
