Comprehensive Technical Analysis of CVE-2024-54921

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: CVE-2024-54921 pertains to a SQL Injection vulnerability in the /student_signup.php script of the kashipara E-learning Management System v1.0. This vulnerability allows remote attackers to execute arbitrary SQL commands via the username, firstname, lastname, and class_id parameters, potentially leading to unauthorized database access.

Severity Evaluation: The CVSS (Common Vulnerability Scoring System) score for this vulnerability is 9.8, which is classified as "Critical." This high score indicates a significant risk to the confidentiality, integrity, and availability of the affected system. The critical nature of the vulnerability is due to the potential for complete database compromise, including data theft, modification, and deletion.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: Attackers can exploit this vulnerability remotely by crafting malicious input for the username, firstname, lastname, and class_id parameters in the /student_signup.php script.
• Automated Scanning: Automated tools and bots can be used to scan for and exploit this vulnerability, increasing the risk of widespread attacks.

Exploitation Methods:

• SQL Injection: Attackers can inject SQL commands into the input fields to manipulate the database. Common techniques include:
  • Union-based SQL Injection: Combining the results of two SELECT statements to extract data.
  • Error-based SQL Injection: Inducing database errors to gather information about the database structure.
  • Blind SQL Injection: Using true/false responses to infer information about the database.

3. Affected Systems and Software Versions

Affected Systems:

• kashipara E-learning Management System v1.0

Software Versions:

• Specifically, the vulnerability is present in version 1.0 of the kashipara E-learning Management System.
