ISSUE:
RCE (Remote Code Execution) attacks were being DETECTED and LOGGED
but NOT BLOCKED, allowing the attacks to proceed even with Score:100.
ROOT CAUSE:
The ET-based blocking only triggered if:
1. Both record_request AND detect_rate_anomaly functions exist AND
2. Combined score >= 90
If either function failed or didn't exist, RCE wasn't immediately blocked.
SOLUTION:
Add explicit, immediate blocking for RCE attacks:
- Detect RCE|WEBSHELL|ECOMMERCE_EXPLOIT in attack types
- Block IMMEDIATELY regardless of score calculation
- Don't wait for rate anomaly detection
- Log as INSTANT_BLOCK_RCE for clear visibility
AFFECTED ATTACKS (Now immediately blocked):
- RCE (Remote Code Execution)
- WEBSHELL (Web shell uploads/access)
- ECOMMERCE_EXPLOIT (Commerce site exploits)
IMPACT:
- 0-second blocking for RCE attempts (previously delayed)
- Prevents exploitation of PHP shells and upload endpoints
- Eliminates time window for attackers to interact with shells
Applied to both live-attack-monitor.sh and live-attack-monitor-v2.sh
