CVE-2024-50766

Comprehensive Technical Analysis of CVE-2024-50766

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-50766 Description: SourceCodester Survey Application System 1.0 is vulnerable to SQL Injection in takeSurvey.php via the id parameter. CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is due to the potential for complete compromise of the database, leading to unauthorized access, data theft, and potential system manipulation. The vulnerability allows attackers to execute arbitrary SQL commands, which can result in severe impacts such as data breaches, data corruption, and loss of data integrity.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: The primary attack vector is SQL Injection, where an attacker can input malicious SQL statements into the id parameter in takeSurvey.php.
• Automated Scanning: Attackers may use automated tools to scan for vulnerable parameters and inject SQL commands.

Exploitation Methods:

• Manual Exploitation: An attacker can manually craft SQL queries to extract data, modify database entries, or delete data.
• Automated Exploitation: Using tools like SQLMap, attackers can automate the process of identifying and exploiting SQL Injection vulnerabilities.

Example Exploit:

id=1' OR '1'='1

This query can bypass authentication or extract sensitive information from the database.
