Overview
A high-severity vulnerability, identified as CVE-2025-13724, has been discovered in the VikRentCar Car Rental Management System plugin for WordPress. This flaw allows authenticated attackers with Administrator-level access or higher to perform time-based blind SQL Injection. The vulnerability exists in all versions of the plugin up to and including 1.4.4. Exploitation of this vulnerability can lead to the extraction of sensitive information from the WordPress database.
Technical Details
The vulnerability stems from insufficient escaping of the user-supplied ‘month’ parameter and a lack of proper sanitization within the existing SQL query. Attackers can inject malicious SQL code into the query through the ‘month’ parameter, specifically in the admin interface when viewing or manipulating rental data. The time-based nature of the SQL injection means attackers can infer data by observing the response time of the server based on conditional SQL statements injected.
CVSS Analysis
- CVE ID: CVE-2025-13724
- Severity: HIGH
- CVSS Score: 7.5
- The vulnerability receives a CVSS score of 7.5, classifying it as High severity. This is due to the combination of factors:
- Authentication Required: Exploitation requires administrative-level access.
- Data Exposure: Successful exploitation leads to the potential disclosure of sensitive information, including user credentials, financial data, and other confidential details stored in the database.
- Complexity: The complexity is relatively high because it’s a blind injection and requires the attacker to craft time-based queries.
Possible Impact
Successful exploitation of this SQL Injection vulnerability can have severe consequences:
- Data Breach: Sensitive data, including user credentials, customer information, and financial details, can be exposed.
- Account Takeover: Attackers can gain control of administrator accounts, leading to complete control over the WordPress site.
- Website Defacement: With administrative access, attackers can modify the website content or redirect users to malicious sites.
- Reputational Damage: A successful attack can severely damage the reputation of the website and the organization behind it.
Mitigation or Patch Steps
The recommended mitigation steps are:
- Update the Plugin: Upgrade the VikRentCar Car Rental Management System plugin to the latest version (greater than 1.4.4) as soon as possible. The update should contain a fix for this SQL Injection vulnerability.
- Web Application Firewall (WAF): Implement a Web Application Firewall (WAF) with rules designed to detect and block SQL Injection attempts.
- Regular Security Audits: Conduct regular security audits of your WordPress website and plugins to identify and address potential vulnerabilities.
