CVE-2023-29629 Scanner

The Prestashop jmsthemelayout module is widely used within the PrestaShop e-commerce platform, particularly in conjunction with themes developed by Joo Masters. This module is integral for managing theme layouts, and it is typically utilized by online retailers aiming to enhance the appearance and structural coherence of their e-commerce sites. Retailers use jmsthemelayout to customize the front-end visuals of their stores, aligning them with specific branding needs. The module finds application across various PrestaShop-based online platforms globally due to its flexible design options. Its ease of use and compatibility with numerous themes make it a preferred choice for those operating within the PrestaShop environment. However, its widespread deployment also necessitates vigilant security checks to ensure seamless and secure operation.

The SQL Injection vulnerability in jmsthemelayout allows attackers to manipulate database queries through maliciously crafted inputs. This vulnerability exists because user inputs are not correctly sanitized before being incorporated into SQL queries. SQL Injection vulnerabilities can lead to unauthorized access to database information, including sensitive customer and transactional data. It is a critical issue due to the potential impact on confidentiality, integrity, and availability of the data. The ability for attackers to execute arbitrary SQL code on the database poses severe risks to the operational integrity of affected sites. Due to its critical nature, addressing this vulnerability swiftly is paramount for maintaining e-commerce site security.

Technical details regarding this vulnerability indicate that the blind SQL Injection flaw is exploitable via the jmsthemelayout module's configuration file, 'config.xml'. Attackers can leverage this entry point by injecting malicious SQL payloads into specific parameters that interact with the database. The vulnerability primarily affects the 'GET' method used in HTTP requests to access the module's configuration. This issue persists in versions up to and including 2.5.5 of the jmsthemelayout module. The exploitation requires no prior authentication, hence broadening the threat vector for malicious parties.

Exploitation of this vulnerability can lead to several adverse effects, including unauthorized data retrieval and manipulation. Attackers might gain access to sensitive user information, disrupt site functionalities, and execute commands that compromise data integrity. In the worst-case scenario, an attacker could obtain administrative access to the website's backend, leading to data breaches or complete site takeover. This not only affects the trust and reliability of the affected businesses but also poses legal and regulatory risks related to data privacy laws. Consequently, unaddressed SQL Injection vulnerabilities can significantly harm organizational reputation and finances.
