Comprehensive Technical Analysis of EUVD-2023-58651

1. Vulnerability Assessment and Severity Evaluation

The vulnerability reported in the Voovi Social Networking Script version 1.0 involves a SQL injection flaw in the perfil.php file, specifically affecting the id and user parameters. This vulnerability allows a remote attacker to execute arbitrary SQL queries on the database, potentially leading to unauthorized access to sensitive information.

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 high base score indicates a critical vulnerability due to the following factors:

• 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 vulnerability poses a significant risk as it can be exploited remotely without any special privileges or user interaction, leading to high impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: The primary attack vector is SQL injection, where an attacker can inject malicious SQL code into the id and user parameters in the perfil.php file.

Exploitation Methods:

• Crafted SQL Queries: An attacker can send specially crafted SQL queries to the server, potentially retrieving, modifying, or deleting data stored in the database.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL injection vulnerabilities, making it easier to identify and exploit this flaw.

3. Affected Systems and Software Versions

Affected Systems:

• Voovi Social Networking Script version 1.0

Software Versions:

• The vulnerability specifically affects version 1.0 of the Voovi Social Networking Script.
