CVE-2019-25526: Inout EasyRooms SQL Injection Vulnerability

CVE-2019-25526 Overview

Inout EasyRooms Ultimate Edition v1.0 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the location parameter. Attackers can send POST requests to the search/searchdetailed endpoint with malicious SQL payloads in the location field to extract sensitive data or modify database contents.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive database information, modify data, or potentially gain unauthorized access to the underlying system without any prior authentication.

Technical Details for CVE-2019-25526

Vulnerability Analysis

This vulnerability falls under CWE-89 (SQL Injection), a critical class of web application security flaws. The Inout EasyRooms Ultimate Edition v1.0 application fails to properly sanitize user-supplied input in the location parameter before incorporating it into SQL queries. This lack of input validation creates a direct pathway for attackers to inject arbitrary SQL commands into the application's database queries.

The vulnerability is particularly severe because it requires no authentication to exploit. An unauthenticated remote attacker can craft malicious HTTP POST requests targeting the search/searchdetailed endpoint, embedding SQL injection payloads within the location field. Upon processing these requests, the application executes the injected SQL code within the context of the database, potentially allowing data exfiltration, data manipulation, or further system compromise.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the application's search functionality. The location parameter from user input is directly concatenated into SQL query strings without proper sanitization, escaping, or the use of bound parameters. This allows specially crafted input containing SQL syntax to modify the intended query logic.

Attack Vector

This vulnerability is exploitable over the network without requiring any user interaction or prior authentication. An attacker sends a crafted HTTP POST request to the vulnerable search/searchdetailed endpoint. The malicious payload is embedded in the location parameter of the POST body. When the server processes this request, the unsanitized input is incorporated directly into a SQL query, allowing the attacker to:

• Extract sensitive information from the database using UNION-based or blind SQL injection techniques
• Modify or delete database records
• Potentially escalate privileges or gain further system access depending on database permissions

Technical details and proof-of-concept information can be found at the Exploit-DB #46630 entry and the VulnCheck Advisory.

Detection Methods for CVE-2019-25526

Indicators of Compromise

• Unusual or malformed HTTP POST requests to the search/searchdetailed endpoint containing SQL syntax characters such as single quotes ('), double dashes (--), semicolons (;), or UNION statements
• Database error messages appearing in HTTP responses that reveal SQL query structure
• Unexpected database queries in logs showing injection patterns or attempts to access system tables
• Anomalous data access patterns indicating bulk extraction of database records

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the location parameter
• Implement application-level logging to capture all requests to the search/searchdetailed endpoint for forensic analysis
• Monitor database query logs for anomalous queries containing UNION, SELECT, or other injection indicators
• Configure intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed access logging on web servers to capture full POST request bodies for the affected endpoint
• Set up alerts for database errors that may indicate failed injection attempts
• Monitor for unusual database query execution times that may suggest blind SQL injection exploitation
• Implement real-time alerting for any access to sensitive database tables from the web application context

How to Mitigate CVE-2019-25526

Immediate Actions Required

• If possible, disable or restrict access to the search/searchdetailed endpoint until a patch is applied
• Implement WAF rules to block requests containing SQL injection payloads in the location parameter
• Review database access controls and ensure the web application uses a database account with minimal required privileges
• Audit database logs for any signs of prior exploitation

Patch Information

No official vendor patch information is currently available in the CVE data. Organizations should monitor the vendor's security advisories and apply updates as soon as they become available. Review the VulnCheck Advisory for the latest remediation guidance.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection detection rules in front of the application
• Implement input validation at the application layer to reject requests containing SQL metacharacters in the location parameter
• Restrict network access to the vulnerable endpoint to trusted IP addresses only
• Consider taking the application offline if it processes sensitive data and no mitigation is feasible
