IMAP (143/993): banner grab + LOGIN brute force
POP3 (110/995): banner grab + USER/PASS brute force
Both registered as safe default plugins with auth-check capability.
Detects exposed JDWP (Java Debug Wire Protocol) services on ports
5005/8000/8787/5050. Performs protocol handshake and reports as VULN
since an exposed debug port allows remote code execution.
SDK enhancements for endpoint agent embedding:
- ScanWithController for pause/resume and live stats
- OnProgress callback for periodic progress reporting
- TaskID injection into every scan result
- ScanController with goroutine-safe pause/resume/stats
- Multi-target stats aggregation (race-free)
UDP plugin infrastructure:
- PluginTypeUDP registry with dedicated dispatch path
- DialUDP on ScanSession with rate limiting and packet counting
- UDP plugins bypass TCP port scan, probe targets directly
- FilterService excludes UDP plugins from TCP port matching
SNMP plugin (first UDP plugin):
- SNMPv2c GetRequest probe for sysDescr detection
- Community string brute force (public/private/community/etc)
- Pure stdlib implementation (encoding/asn1)
- Registered as safe default plugin on port 161/UDP
Tests: 95.7% SDK coverage, race-free, 50+ new test cases
