CVE-2024-51601 identifies a classic SQL Injection vulnerability in the Maksym Marko Website price calculator plugin, versions up to and including 4.1. The vulnerability arises from improper neutralization of special characters in SQL commands constructed by the plugin, allowing attackers to inject arbitrary SQL code. This can lead to unauthorized access to the backend database, enabling attackers to read, modify, or delete data, or potentially escalate privileges within the application. The flaw is typical of insufficient input sanitization or parameterization in the plugin's code handling user-supplied input for price calculations. Although no known public exploits currently exist, the vulnerability is publicly disclosed and could be targeted by attackers once details become widespread. The plugin is used to embed price calculation functionality on websites, meaning any site integrating this component is vulnerable. The lack of an official patch or update at the time of disclosure increases risk. The vulnerability does not require authentication but does require user interaction through the price calculator interface. The absence of a CVSS score necessitates an expert severity assessment based on impact and exploitability factors.

The potential impact of this SQL Injection vulnerability is significant for organizations using the Maksym Marko Website price calculator plugin. Attackers exploiting this flaw could gain unauthorized access to sensitive data stored in the website's database, including customer information, pricing data, or business logic details. They could also manipulate or delete data, causing data integrity issues and operational disruption. In some cases, SQL Injection can be leveraged to execute commands on the underlying server, leading to full system compromise. The vulnerability could also facilitate further attacks such as privilege escalation or lateral movement within the network. For e-commerce or service websites relying on accurate price calculations, exploitation could result in financial loss or reputational damage. The lack of a patch means organizations remain exposed until mitigations are applied. The risk is amplified for websites with high traffic or those integrated with other critical systems.

Organizations should immediately audit their use of the Maksym Marko Website price calculator plugin and identify affected versions (up to 4.1). Until an official patch is released, implement a Web Application Firewall (WAF) with strong SQL Injection detection and prevention rules to block malicious payloads targeting the price calculator endpoints. Review and harden input validation and sanitization routines, ensuring all user inputs are properly parameterized and escaped before database queries. Consider temporarily disabling or removing the plugin if feasible to eliminate exposure. Monitor web server and application logs for suspicious activity indicative of SQL Injection attempts. Engage with the vendor or community to track patch releases and apply updates promptly once available. Conduct penetration testing focused on SQL Injection vectors in the price calculator functionality. Additionally, isolate the web application database with strict access controls and least privilege principles to limit potential damage from exploitation.
