They unconditionally return fixed records for `192.168.1.88` and `192.168.1.100`. Although the constructor stores the user-supp ...[truncated 1682 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Implement actual discovery only where it is authorized and necessary: - Parse the target with Python's `ipaddress.ip_network()`. - Reject malformed targets, multicast ranges, and targets outside explicitly permitted networks. - Enforce maximum subnet sizes to prevent unintended broad scanning. - Apply connection, read, and overall scan timeouts. 2. Perform protocol-specific verification rather than inferring a device solely from an open port. 3. For S2 discovery, capture and validate real heartbeat messages and authenticate any TLS handshake before reporting vendor metadata. 4. Include evidence in each result, such as the observed endpoint, timestamp, validated protocol response, and verification outcome. 5. If the package is intended only as a demonstration, rename the methods and status fields to clearly indicate simulation, require an explicit `--demo` option, and mark every generated record as synthetic. 6. Add tests confirming that different subnets do not produce predetermined findings and that unreachable networks produce an empty or failed result rather than successful discoveries. ]]>
