The EUVD entry EUVD-2024-49202 describes a SQL injection vulnerability in the Job Portal software, specifically in the /jobportal/admin/employee/index.php file through the id parameter. The vulnerability allows an attacker to send a specially crafted query to retrieve all information stored in the database.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS vector indicates:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high severity score underscores the critical nature of the vulnerability, which can lead to significant data breaches and system compromises.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attack: The attacker can exploit the vulnerability remotely over the network.
• SQL Injection: The attacker can inject malicious SQL queries through the id parameter in the URL.

Exploitation Methods:

• Crafted SQL Queries: An attacker can send specially designed SQL queries to extract sensitive information, manipulate data, or execute unauthorized commands.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL injection vulnerabilities.

3. Affected Systems and Software Versions

Affected Software:

• Product: Job Portal
• Version: 1.0
• Vendor: PHPGurukul

Affected Systems:

• Any system running the Job Portal software version 1.0 is vulnerable to this SQL injection attack.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest security patches provided by the vendor.
• Input Validation: Implement strict input validation and sanitization for the id parameter.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts.

Long-Term Mitigation:

• Regular Security Audits: Conduct regular security audits and code reviews.
• Security Training: Provide security training for developers to prevent similar vulnerabilities in future releases.
• Monitoring: Implement continuous monitoring and logging to detect and respond to suspicious activities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using the Job Portal software, particularly those in the European Union. The potential for data breaches, unauthorized access, and data manipulation can lead to severe financial and reputational damage. Compliance with GDPR and other data protection regulations may also be compromised, leading to legal consequences.

6. Technical Details for Security Professionals

Vulnerability Details:

• Vulnerable Parameter: id in /jobportal/admin/employee/index.php
• Exploitation: An attacker can inject SQL commands through the id parameter to execute arbitrary queries.

Example Exploit:

/jobportal/admin/employee/index.php?id=1' OR '1'='1

This query can bypass authentication or retrieve unauthorized data.

Detection:

• Log Analysis: Monitor web server logs for unusual SQL query patterns.
• Intrusion Detection Systems (IDS): Use IDS to detect and alert on SQL injection attempts.

Remediation:

• Code Review: Ensure all SQL queries use parameterized statements.
• Database Permissions: Limit database permissions to the minimum required for application functionality.
