CVE-2024-54842

Comprehensive Technical Analysis of CVE-2024-54842

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-54842 CISA Vulnerability Name: CVE-2024-54842 Description: A SQL injection vulnerability was found in phpgurukul Online Nurse Hiring System v1.0 in /admin/password-recovery.php via the mobileno 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 system compromise, including unauthorized access to sensitive data, data manipulation, and potential loss of data integrity and confidentiality.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: An attacker can inject malicious SQL code into the mobileno parameter in the password recovery form. This can lead to unauthorized database queries, data extraction, and potential manipulation of database records.
• Data Exfiltration: By exploiting this vulnerability, an attacker can extract sensitive information such as user credentials, personal information, and other confidential data stored in the database.
• Privilege Escalation: If the database contains administrative credentials or other sensitive information, an attacker could escalate privileges and gain further access to the system.

Exploitation Methods:

• Manual Exploitation: An attacker can manually craft SQL injection payloads and input them into the mobileno parameter to test for vulnerabilities.
• Automated Tools: Attackers may use automated SQL injection tools like SQLmap to identify and exploit the vulnerability efficiently.

3. Affected Systems and Software Versions

Affected Software:

• phpgurukul Online Nurse Hiring System v1.0

Specific Component:

• /admin/password-recovery.php

Parameter:

• mobileno

• Increased Awareness: This vulnerability highlights the importance of secure coding practices and the need for continuous security monitoring and updates.
• Regulatory Compliance: Organizations may face regulatory penalties and legal consequences if sensitive data is compromised due to this vulnerability.

6. Technical Details for Security Professionals

Vulnerability Details:

• Location: The vulnerability is located in the /admin/password-recovery.php file, specifically in the handling of the mobileno parameter.
• Exploit: The vulnerability can be exploited by injecting SQL code into the mobileno parameter, which is not properly sanitized or validated.

Example Exploit Payload:

mobileno=123456' OR '1'='1

Mitigation Code Example:

// Using prepared statements in PHP
$stmt = $pdo->prepare("SELECT * FROM users WHERE mobileno = :mobileno");
$stmt->bindParam(':mobileno', $mobileno);
$stmt->execute();
