Overview
A high-severity SQL injection vulnerability, identified as CVE-2025-14091, has been discovered in TrippWasTaken PHP-Guitar-Shop, specifically in versions up to commit 6ce0868889617c1975982aae6df8e49555d0d555. This vulnerability allows remote attackers to execute arbitrary SQL commands by manipulating the ID argument in the /product.php file. This could lead to data breaches, modification of data, or even complete compromise of the database server. Unfortunately, the vendor has not responded to attempts at responsible disclosure, making mitigation challenging.
Technical Details
The vulnerability resides within the Product Details Page functionality (/product.php). The application fails to properly sanitize user-supplied input provided through the ID parameter when retrieving product information from the database. An attacker can inject malicious SQL code into the ID parameter, which will then be executed by the database. This SQL injection allows the attacker to bypass authentication mechanisms, extract sensitive data, modify existing data, or even potentially execute operating system commands, depending on the database server’s configuration and permissions.
The publicly available exploit demonstrates how to leverage this vulnerability to extract database information. Given the lack of vendor response, a proof of concept and attack details are readily available, increasing the risk of exploitation.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-14091 is 7.3, classifying it as HIGH severity.
- CVSS Score: 7.3
- Vector: (Calculated value based on attack vector, complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact)
- Severity: HIGH
This high score reflects the vulnerability’s remote exploitability, low attack complexity, and potential for significant impact on data confidentiality, integrity, and availability.
Possible Impact
Successful exploitation of this vulnerability can have severe consequences:
- Data Breach: Attackers can gain access to sensitive customer data, including usernames, passwords, addresses, and payment information.
- Data Manipulation: Attackers can modify or delete data, potentially disrupting operations or causing financial losses.
- Account Takeover: Attackers can hijack user accounts and perform unauthorized actions.
- Denial of Service (DoS): Attackers can crash the database server, rendering the application unavailable.
- Complete System Compromise: Depending on the database server’s configuration, attackers might be able to execute arbitrary code on the underlying operating system, leading to complete system compromise.
Mitigation Steps
Due to the vendor’s lack of response and the rolling release model, a traditional patch is unlikely to be available. Therefore, the following mitigation steps are crucial:
- Input Validation: Implement robust input validation and sanitization for all user-supplied data, especially the
IDparameter in/product.php. Ensure that only expected data types and formats are allowed. Use parameterized queries or prepared statements to prevent SQL injection. - Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) and configure it to block SQL injection attempts. Regularly update the WAF’s ruleset to protect against emerging threats.
- Database Permissions: Review and restrict database user permissions. Grant only the necessary privileges to the application’s database user. Avoid using the
rootorsaaccount for application access. - Code Review: Conduct a thorough code review of the
/product.phpfile and any related database interaction logic to identify and remediate other potential vulnerabilities. - Monitor and Alert: Implement comprehensive monitoring and alerting to detect suspicious activity, such as unusual database queries or error messages.
- Consider Alternative Solutions: If maintaining a secure version of TrippWasTaken PHP-Guitar-Shop proves too difficult, consider migrating to a more actively maintained and secure e-commerce platform.
