CVE-2005-0868: AS/400 Telnet 5250 terminal emulation clients, as implemented by (1) IBM client access, (2) Bosanova, (3) P...

Security readout for executives and security teams

This issue affects legacy AS/400 5250 terminal emulation clients. A malicious or compromised AS/400 server could make a connected PC run commands through terminal features intended to start PC-side actions. That creates workstation compromise risk, but the public bundle does not name versions, patches, or active exploitation. Exposure is likely limited to organizations still using AS/400 or iSeries 5250 terminal emulation clients, particularly the named products. Version and platform details are not provided in the source bundle, so vulnerability managers should verify actual client behavior rather than assume all installations are affected. Treat this as a targeted legacy-environment risk. It is not broadly internet-facing from the evidence provided, but affected workstations could be compromised if they connect to a malicious or compromised AS/400 server. Prioritize inventory and vendor verification where AS/400 access remains business-critical. Mitigation focus: Inventory 5250 terminal emulators and identify the named products in active use.; Check vendor advisories or support channels for affected versions and fixes.; Restrict terminal clients to trusted AS/400 or iSeries hosts only..
