# CVE-2023-34362: Vulnerability Defense Package
This repository provides a complete threat-informed defense package for **CVE-2023-34362**, a critical SQL Injection and Remote Code Execution (RCE) vulnerability in **Progress MOVEit Transfer**, exploited by the CL0P ransomware group.
---
## 🔍 Executive Summary
CVE-2023-34362 is a critical vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries and escalate to remote code execution using insecure deserialization. Real-world attacks by the CL0P ransomware group involved data theft and persistence via a custom web shell named `LEMURLOOT`. This package presents detailed exploit analysis, detection rules, and mitigation strategies.

## 🛠️ Detection Engineering
### Suricata Rules
See [`/suricata_rules/moveit_sqli.rules`](./suricata_rules/moveit_sqli.rules)
- Detects SQLi setup via `/moveitisapi.dll?action=m2`
- Detects web shell access via `human2.aspx` + custom headers
### Sigma Rules
See [`/sigma_rules/`](./sigma_rules/)
- Detects access to web shell (`human2.aspx`) in IIS logs
- Detects suspicious child processes from `w3wp.exe`
---
## 🧪 Indicators of Compromise (IOCs)
See [`/iocs/indicators.txt`](./iocs/indicators.txt)
Includes:
- File paths: `human2.aspx`, `message.txt`
- Header values: `X-siLock-Comment`, etc.
- User accounts: `Health Check Service`
- Process chains and SQL anomalies
---
## 🛡️ Mitigation & Hardening Recommendations
- Apply official MOVEit patches immediately
- Restrict public access to guest and API endpoints
- Deploy WAF and endpoint telemetry (EDR)
- Monitor web root for unauthorized `.aspx` files
- Detect abnormal process trees (e.g., `w3wp.exe → powershell.exe`)
