Comprehensive Technical Analysis of EUVD-2025-37495

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The Car-Booking-System-PHP v.1.0 is susceptible to SQL Injection in the /carlux/sign-in.php script. SQL Injection is a critical vulnerability that allows attackers to execute arbitrary SQL commands on the database by manipulating input fields.

Severity Evaluation: The Base Score of 9.8, as per CVSS v3.1, indicates a critical vulnerability. The vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill and resources.
• Privileges Required (PR): None (N) - No special privileges are needed to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - Complete loss of confidentiality.
• Integrity (I): High (H) - Complete loss of integrity.
• Availability (A): High (H) - Complete loss of availability.

This high severity score underscores the critical nature of the vulnerability, necessitating immediate attention.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Direct SQL Injection: Attackers can input malicious SQL queries directly into the sign-in form fields.
• Blind SQL Injection: Attackers can use techniques to infer database structure and data by observing application behavior.
• Error-Based SQL Injection: Attackers can exploit error messages returned by the application to gain information about the database.

Exploitation Methods:

• Manual Exploitation: Crafting SQL queries manually and injecting them into the input fields.
• Automated Tools: Using automated tools like SQLMap to detect and exploit SQL Injection vulnerabilities.
• Scripting: Writing custom scripts to automate the injection process and extract data.

3. Affected Systems and Software Versions

Affected Systems:

• Any system running Car-Booking-System-PHP v.1.0.
• Web servers hosting the vulnerable application.
• Databases connected to the affected application.

Software Versions:

• Car-Booking-System-PHP v.1.0

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by the vendor.
