CVE-2017-17628
📋 TL;DR
CVE-2017-17628 is a SQL injection vulnerability in Responsive Realestate Script 3.2 that allows attackers to execute arbitrary SQL commands via the 'tbud' parameter in the property-list feature. This affects all installations of Responsive Realestate Script version 3.2 that expose the vulnerable endpoint. Attackers can potentially access, modify, or delete database content.

📦 What is this software?
Responsive Realestate Script by Responsive Realestate Script Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, authentication bypass, and potential remote code execution if database functions allow command execution.
Likely Case
Unauthorized data access, extraction of sensitive information (user credentials, property data, personal information), and potential privilege escalation.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database permissions restricting unauthorized access.
🎯 Exploit Status
Public exploit code is available on Exploit-DB and Packet Storm. The vulnerability requires no authentication and exploitation is straightforward with available tools.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement manual fixes by sanitizing the 'tbud' parameter input and using parameterized queries.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd server-side validation to sanitize the 'tbud' parameter, rejecting malicious input containing SQL injection patterns.
Edit the PHP file handling property-list requests to add: if (preg_match('/[^a-zA-Z0-9]/', $_GET['tbud'])) { die('Invalid input'); }
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns in the 'tbud' parameter.
Add WAF rule: SecRule ARGS:tbud "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"
🧯 If You Can't Patch
- Isolate the affected system behind a firewall, restricting access to trusted IPs only.
- Implement network segmentation to limit the blast radius if the system is compromised.
🔍 How to Verify
Check if Vulnerable:
Test by sending a crafted request to the property-list endpoint with a malicious 'tbud' parameter (e.g., ' OR '1'='1) and observe if SQL errors or unexpected data is returned.Check Version:
Check the script version in the admin panel or review the source code for version indicators.Verify Fix Applied:
After applying fixes, retest with the same malicious input; the system should reject the request or return no sensitive data.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in web server logs
- Multiple requests to property-list with suspicious 'tbud' parameter values
- High volume of requests from single IPs to vulnerable endpoint
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in the 'tbud' parameter
- Abnormal traffic patterns to the property-list endpoint
SIEM Query:
source="web_logs" AND uri="/property-list" AND (param="tbud" AND value MATCHES "(?i)(SELECT|UNION|OR|AND|--|#)")
