CVE-2024-8669

Comprehensive Technical Analysis of CVE-2024-8669

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-8669

Description: The Backuply – Backup, Restore, Migrate and Clone plugin for WordPress is vulnerable to SQL Injection via the 'options' parameter passed to the backuply_wp_clone_sql() function in all versions up to, and including, 1.3.4. This vulnerability arises due to insufficient escaping of user-supplied parameters and lack of proper preparation of existing SQL queries.

CVSS Score: 9.1

Severity Evaluation:

• Critical: The high CVSS score of 9.1 indicates a critical vulnerability. The potential for authenticated attackers with administrator-level access to execute arbitrary SQL queries poses a significant risk to the integrity and confidentiality of the database.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Authenticated Attack: An attacker with administrator-level access can exploit this vulnerability by injecting malicious SQL code into the 'options' parameter.
• SQL Injection: The lack of proper escaping and preparation of SQL queries allows attackers to append additional SQL queries, which can be used to extract sensitive information, modify data, or execute unauthorized commands.

Exploitation Methods:

• Data Exfiltration: Attackers can extract sensitive information such as user credentials, personal data, and configuration settings.
• Data Manipulation: Attackers can modify database entries, leading to unauthorized changes in the application's behavior.
• Privilege Escalation: Although the attacker needs administrator-level access to exploit this vulnerability, they can further escalate privileges or gain unauthorized access to other parts of the system.

3. Affected Systems and Software Versions

Affected Software:

• Backuply – Backup, Restore, Migrate and Clone plugin for WordPress
