CVE-2019-25455: Web-ofisi E-ticaret SQLi Vulnerability

CVE-2019-25455 Overview

Web Ofisi E-Ticaret v3 contains an SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the a parameter. Attackers can send GET requests with malicious a parameter values to extract sensitive database information, potentially compromising the entire e-commerce platform's data integrity and confidentiality.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability to extract sensitive customer data, payment information, and administrative credentials from the database without any prior authentication.

Affected Products

• Web-ofisi E-Ticaret version 3.0.0
• web-ofisi e-ticaret

Technical Details for CVE-2019-25455

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) affects the Web Ofisi E-Ticaret v3 e-commerce platform, specifically targeting the a parameter in HTTP GET requests. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries, allowing attackers to inject arbitrary SQL statements.

The vulnerability is particularly dangerous because it requires no authentication to exploit. An attacker can craft malicious GET requests containing SQL payloads in the a parameter, which are then executed directly against the backend database. This can lead to unauthorized data extraction, including customer personal information, order details, and administrative credentials.

The network-based attack vector with low complexity makes this vulnerability highly accessible to attackers with basic SQL injection knowledge. The impact primarily affects data confidentiality with high severity, along with limited integrity impact on the vulnerable system.

Root Cause

The root cause of this vulnerability is improper input validation and sanitization in the Web Ofisi E-Ticaret v3 application. The a parameter accepts user input that is directly concatenated into SQL queries without proper parameterization or escaping. This classic SQL injection pattern occurs when developers fail to implement prepared statements or parameterized queries, allowing malicious SQL code to be executed by the database engine.

Attack Vector

The attack is executed over the network via HTTP GET requests targeting the vulnerable a parameter. An unauthenticated attacker can craft specially formatted requests containing SQL injection payloads to:

1. Extract database schema information using UNION-based injection techniques
2. Dump sensitive tables containing customer data, credentials, and payment information
3. Potentially modify or delete database records depending on database permissions
4. Enumerate database users and attempt privilege escalation within the database

The exploitation requires no user interaction and can be automated using common SQL injection tools. For technical details on the exploitation methodology, refer to the Exploit-DB #47139 and the VulnCheck SQL Injection Advisory.

Detection Methods for CVE-2019-25455

Indicators of Compromise

• Unusual GET requests containing SQL keywords (UNION, SELECT, FROM, WHERE, OR, AND) in the a parameter
• Database error messages appearing in HTTP responses or application logs
• Abnormal database query patterns including time-based delays or large data extractions
• Web server logs showing repeated requests with varying payloads to the same endpoint

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the a parameter
• Implement database activity monitoring to identify unusual query patterns or unauthorized data access
• Configure IDS/IPS signatures to detect common SQL injection payloads in HTTP traffic
• Review web server access logs for suspicious request patterns targeting the vulnerable endpoint

Monitoring Recommendations

• Enable detailed logging for all database queries and monitor for anomalous patterns
• Set up alerts for multiple failed database queries or syntax errors within short time periods
• Monitor outbound data transfers from the database server for potential data exfiltration
• Implement real-time log analysis to correlate web requests with database activity

How to Mitigate CVE-2019-25455

Immediate Actions Required

• Restrict access to the affected endpoint using network-level controls or application firewall rules
• Deploy WAF rules specifically targeting SQL injection attempts in the a parameter
• Review database permissions and apply principle of least privilege to the application's database user
• Audit database logs for evidence of prior exploitation attempts

Patch Information

No vendor patch information is currently available in the CVE data. Contact Web Ofisi directly for security updates or consider upgrading to a newer version of the e-commerce platform if available. Refer to the Web Ofisi E-Ticaret Details page for product information.

Workarounds

• Implement input validation at the application level to sanitize the a parameter before database queries
• Use parameterized queries or prepared statements to prevent SQL injection
• Deploy a reverse proxy with SQL injection filtering capabilities in front of the application
• Consider temporarily disabling the vulnerable functionality until a proper fix is implemented
