CVE-2024-29732

Comprehensive Technical Analysis of CVE-2024-29732

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-29732 Description: A SQL Injection vulnerability has been identified in the SCAN_VISIO eDocument Suite Web Viewer of Abast. This vulnerability allows an unauthenticated user to perform SQL Injection attacks via the "user" parameter on the login page, potentially leading to unauthorized retrieval, update, and deletion of database information.

CVSS Score: 9.8 Severity: Critical

The CVSS score of 9.8 indicates a highly critical vulnerability. The severity is amplified by the fact that it allows unauthenticated access, which significantly increases the risk of exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The vulnerability can be exploited without requiring any authentication, making it accessible to any attacker with network access to the login page.
• SQL Injection: The attacker can inject malicious SQL queries through the "user" parameter on the login page.

Exploitation Methods:

• Data Exfiltration: Attackers can craft SQL queries to extract sensitive information from the database.
• Data Manipulation: Attackers can update or delete database records, leading to data integrity issues.
• Privilege Escalation: By manipulating SQL queries, attackers may gain elevated privileges within the application or database.

3. Affected Systems and Software Versions

Affected Software:

• SCAN_VISIO eDocument Suite Web Viewer by Abast

Affected Versions:

Long-Term Impact:

• Reputation Damage: Organizations experiencing data breaches due to this vulnerability may suffer significant reputation damage.
• Increased Awareness: This vulnerability highlights the importance of secure coding practices and the need for continuous security assessments.

6. Technical Details for Security Professionals

Vulnerability Details:

• Location: The vulnerability is located in the login page of the SCAN_VISIO eDocument Suite Web Viewer.
• Parameter: The "user" parameter is susceptible to SQL Injection.

Exploitation Example:

' OR '1'='1

This simple SQL Injection payload can bypass authentication mechanisms if not properly sanitized.

Mitigation Code Example:

# Example using parameterized queries in Python with SQLite
import sqlite3

def login(user):
    conn = sqlite3.connect('database.db')
    cursor = conn.cursor()
    query = "SELECT * FROM users WHERE username = ?"
    cursor.execute(query, (user,))
    result = cursor.fetchone()
    conn.close()
    return result
