Cheyenne InocuLAN Anti-Virus Server in Inoculan 4.0 before Service Pack 2 creates an update directory with "EVERYONE FULL CONTROL" permissions, which allows local users to cause Inoculan's antivirus update feature to install a Trojan horse dll.

Security readout for executives and security teams

This old InocuLAN issue is a permissions mistake. The antivirus server created an update directory writable by everyone, letting a local user place a malicious DLL where the product’s update process could install it. The business risk is highest on legacy Windows NT-era systems still running Inoculan 4.0 before Service Pack 2. Exposure is likely limited to legacy environments running Cheyenne InocuLAN/Inoculan 4.0 before Service Pack 2, especially Windows NT-era hosts. The bundle does not identify modern CPEs or broader affected products. Treat this as a legacy-system hygiene issue unless active InocuLAN deployments are found. If present, prioritize remediation because antivirus infrastructure is trusted software and compromise of its update path can undermine endpoint defenses. Mitigation focus: Upgrade Inoculan 4.0 systems to Service Pack 2 or later where still supported.; Remove EVERYONE FULL CONTROL from antivirus update directories.; Apply least-privilege ACLs consistent with vendor guidance..
