The Net Direct client for Linux before 6.0.5 in Nortel Application Switch 2424, VPN 3050 and 3070, and SSL VPN Module 1000 extracts and executes files with insecure permissions, which allows local users to exploit a race condition to replace a world-writable file in /tmp/NetClient and cause another user to execute arbitrary code when attempting to execute this client, as demonstrated by replacing /tmp/NetClient/client.

Security readout for executives and security teams

This is a legacy local-code-execution flaw in Nortel’s Linux Net Direct VPN client. A local user on the same Linux system could tamper with insecure temporary files created by the client and cause another user to run attacker-controlled code. It matters most on shared Linux workstations or jump hosts still using the old client. Exposure is likely limited to legacy Linux endpoints that still have the Nortel Net Direct client installed, especially multi-user systems. Internet-facing appliances alone are not shown as directly exploitable by the CVE text. Treat this as a legacy cleanup and exposure-reduction item, not an emergency internet-wide event. Prioritize it if shared Linux hosts, privileged administrators, or old Nortel VPN infrastructure remain in use. Mitigation focus: Inventory Linux systems for Nortel Net Direct client versions before 6.0.5.; Upgrade to Net Direct client 6.0.5 or later where vendor guidance supports it.; Remove unused legacy Nortel VPN clients from Linux endpoints..
