CVE-2023-42405
📋 TL;DR
This SQL injection vulnerability in FIT2CLOUD RackShift v1.7.1 allows attackers to execute arbitrary SQL commands via the 'sort' parameter in multiple service endpoints. Attackers could potentially gain unauthorized access to the database, extract sensitive information, or execute arbitrary code. Organizations running RackShift v1.7.1 are affected.
💻 Affected Systems
- FIT2CLOUD RackShift
📦 What is this software?
Rackshift by Fit2cloud
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code, exfiltrate all database contents, pivot to other systems, and maintain persistent access.
Likely Case
Database information disclosure including credentials, configuration data, and sensitive business information, potentially leading to further system compromise.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing without modification privileges.
🎯 Exploit Status
SQL injection via HTTP parameters is a well-understood attack vector with many available tools. The vulnerability requires no authentication, making exploitation straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v1.7.2 or later
Vendor Advisory: https://github.com/fit2cloud/rackshift/issues/79
Restart Required: Yes
Instructions:
1. Backup current configuration and data. 2. Download RackShift v1.7.2 or later from official repository. 3. Stop RackShift service. 4. Replace application files with patched version. 5. Restart RackShift service. 6. Verify functionality.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns in the 'sort' parameter
# Example ModSecurity rule: SecRule ARGS:sort "@detectSQLi" "id:1001,phase:2,deny,status:403"
Input Validation Filter
allAdd middleware to validate and sanitize 'sort' parameter before processing
# Example Python Flask middleware: def validate_sort_param(sort_value): return re.sub(r'[^a-zA-Z0-9_,\s]', '', sort_value)
🧯 If You Can't Patch
- Implement network segmentation to isolate RackShift instances from sensitive systems
- Deploy database monitoring to detect SQL injection attempts and unusual queries
🔍 How to Verify
Check if Vulnerable:
Check if RackShift version is 1.7.1 by accessing the web interface or checking application files. Test by sending a request with SQL injection payload in 'sort' parameter to vulnerable endpoints.Check Version:
curl -s http://rackshift-host/api/version | grep versionVerify Fix Applied:
After patching, attempt SQL injection test with payloads like 'sort=1;SELECT SLEEP(5)--' and verify no delay or error occurs. Confirm version shows 1.7.2 or later.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- HTTP requests containing SQL keywords in 'sort' parameter
- Multiple failed login attempts following suspicious requests
Network Indicators:
- HTTP POST/GET requests to /api/taskService/list, /api/bareMetalService/list, or /api/switchService/list with SQL injection patterns
SIEM Query:
source="web_logs" AND (uri_path="/api/taskService/list" OR uri_path="/api/bareMetalService/list" OR uri_path="/api/switchService/list") AND query_string="*sort=*" AND (query_string="*SELECT*" OR query_string="*UNION*" OR query_string="*OR*" OR query_string="*--*" OR query_string="*;*")
