The problem is due to insufficient bounds checking for the Notes_ExecDirectory environment variable. An attacker can use a string for Notes_ExecDirectory that, when processed, will execute arbitrary code. Technical Recommendation: Upgrade with the latest version available. Lotus Domino version 5.0.9a is not vulnerable to the issue.
