Security readout for executives and security teams
This CVE describes a file-reading flaw in the web server for 3Com Network Supervisor 5.0.2. A remote attacker could use directory traversal patterns in a URL to read files the service can access. Business urgency depends on whether this legacy product is still deployed and reachable on TCP port 21700. Likely exposure is limited to organizations still running 3Com Network Supervisor 5.0.2. Risk increases if its web server is reachable from untrusted networks on TCP port 21700. The source bundle does not identify other affected versions or products. Prioritize discovery and exposure reduction. This is a legacy remote file-read issue with incomplete public severity data, so the main business risk is unmanaged old infrastructure exposed to untrusted networks. Mitigation focus: Identify any 3Com Network Supervisor 5.0.2 installations.; Restrict access to TCP port 21700 to trusted administrative networks.; Check 3Com or successor vendor guidance for fixes or retirement advice..
