CVE-2023-39642

Comprehensive Technical Analysis of CVE-2023-39642

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-39642 Description: Carts Guru cartsguru up to version 2.4.2 contains a SQL injection vulnerability via the component CartsGuruCatalogModuleFrontController::display(). 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 unauthorized access, data breaches, and system compromise. SQL injection vulnerabilities are particularly dangerous because they can allow attackers to execute arbitrary SQL commands, potentially leading to data theft, data manipulation, or complete system takeover.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: An attacker could exploit this vulnerability without needing to authenticate, making it a high-risk vector.
• Web Application Interface: The vulnerability is present in the web application interface, specifically in the CartsGuruCatalogModuleFrontController::display() method.

Exploitation Methods:

• SQL Injection: An attacker can inject malicious SQL code into the input fields processed by the display() method. This can be done through crafted HTTP requests.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL injection vulnerabilities, making it easier to target multiple systems.

3. Affected Systems and Software Versions

Affected Software:

• Carts Guru cartsguru versions up to and including 2.4.2.

Affected Systems:

• Any system running the vulnerable versions of Carts Guru cartsguru, particularly those integrated with PrestaShop.
