AI-analyzed exploit summary This exploit leverages a race condition in the Nortel SSL VPN Linux Client (pre-6.05) where world-writable files in /tmp/NetClient are replaced to achieve local privilege escalation. It either spawns a setuid root shell or executes arbitrary commands as root.

Description

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.
