CVE-2019-25461: Web-ofisi Ticaret SQL Injection Flaw

CVE-2019-25461 Overview

Web Ofisi Platinum E-Ticaret v5 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the q parameter. Attackers can send POST requests to the ajax/productsFilterSearch endpoint with malicious q values using time-based blind SQL injection techniques to extract sensitive database information.

Critical Impact

Unauthenticated attackers can exploit this SQL injection flaw to extract sensitive database information, potentially compromising customer data, credentials, and business-critical information stored in the e-commerce platform's database.

Affected Products

• Web Ofisi Platinum E-Ticaret v5
• web-ofisi ticaret version 5.0.0

Technical Details for CVE-2019-25461

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists in the product search functionality of Web Ofisi Platinum E-Ticaret v5. The application fails to properly sanitize user-supplied input in the q parameter when processing product filter search requests. This allows attackers to inject arbitrary SQL commands that are executed directly against the underlying database.

The vulnerability is particularly dangerous because it requires no authentication to exploit. An attacker can send specially crafted POST requests to the ajax/productsFilterSearch endpoint, leveraging time-based blind SQL injection techniques to systematically extract data from the database without any visible error messages or direct output.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries in the product search functionality. The q parameter value is concatenated directly into SQL queries without proper sanitization or escaping, allowing attackers to break out of the intended query structure and inject their own SQL commands.

Attack Vector

The attack is network-based and can be executed remotely without authentication. An attacker crafts malicious POST requests targeting the ajax/productsFilterSearch endpoint with SQL injection payloads in the q parameter. By using time-based blind SQL injection techniques, the attacker can infer database contents based on response timing differences, allowing systematic extraction of sensitive information including user credentials, customer data, and administrative details.

The exploitation involves sending conditional SQL statements that cause deliberate delays when certain conditions are true, enabling attackers to extract data character by character. Technical details and proof-of-concept information can be found in the Exploit-DB #47140 advisory.

Detection Methods for CVE-2019-25461

Indicators of Compromise

• Unusual POST requests to the ajax/productsFilterSearch endpoint with abnormally long or suspicious q parameter values
• Database query logs showing time-based SQL functions such as SLEEP(), BENCHMARK(), or WAITFOR DELAY
• Multiple sequential requests to the same endpoint with incrementally modified payloads
• Web server logs indicating repeated requests with SQL keywords in parameters

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in POST parameters targeting the product search endpoint
• Configure database activity monitoring to alert on queries containing time-delay functions or UNION-based injection attempts
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection payloads
• Monitor application logs for anomalous request patterns to the ajax/productsFilterSearch endpoint

Monitoring Recommendations

• Enable detailed logging on all web application endpoints, particularly those handling search functionality
• Set up alerting for database queries with unusual execution times that may indicate time-based injection attempts
• Implement rate limiting on the ajax/productsFilterSearch endpoint to slow automated exploitation
• Review web server access logs regularly for patterns consistent with SQL injection reconnaissance

How to Mitigate CVE-2019-25461

Immediate Actions Required

• Restrict access to the ajax/productsFilterSearch endpoint via firewall rules or web application firewall until patching is possible
• Implement input validation to reject requests containing SQL keywords or special characters in the q parameter
• Deploy a Web Application Firewall with SQL injection protection rules
• Review database accounts used by the application and ensure they have minimal required privileges

Patch Information

Contact Web-Ofisi for the latest security patches for Platinum E-Ticaret v5. Additional vulnerability details are available in the VulnCheck Security Advisory. Product information can be found at the Web-Ofisi Product Details page.

Workarounds

• Implement prepared statements or parameterized queries for all database interactions in the affected search functionality
• Add server-side input validation to sanitize the q parameter before processing
• Deploy a reverse proxy with SQL injection filtering capabilities in front of the application
• Consider temporarily disabling the product filter search feature if it is not business-critical while awaiting a vendor patch
