The request_list_request AJAX call of the Car Seller - Auto Classifieds Script WordPress plugin through version 2.1.0 is vulnerable to SQL Injection. This vulnerability allows both authenticated and unauthenticated users to exploit the system by manipulating the order_id POST parameter, which is used in a SQL statement without proper sanitization, validation, or escaping. With a CVSS score of 9.8, this vulnerability is classified as critical, indicating a severe risk to affected systems.
Risk to organizations includes unauthorized access to sensitive data, potential data corruption, and denial of service. The vulnerability's criticality is underscored by its high exploitability, as it can be triggered remotely without the need for authentication, making it a prime target for attackers.
Organizations should prioritize patching immediately. The vulnerability was published on May 14, 2021, and affects the Car Seller - Auto Classifieds Script plugin in all versions prior to the vendor patch. Current status indicates that there are no public exploits confirmed or known exploitation in the wild.
Given the nature of this vulnerability, it is crucial for organizations using the affected plugin to assess their exposure and implement the necessary updates or patches as soon as they are available.
Vulnerability Details
The Car Seller - Auto Classifieds Script WordPress plugin is affected by a SQL Injection vulnerability due to improper handling of the order_id POST parameter in the request_list_request AJAX call. This issue allows attackers to execute arbitrary SQL commands, potentially leading to data leakage or corruption.
With a CVSS score of 9.8, this vulnerability falls under the critical severity classification, primarily due to its high impact on confidentiality, integrity, and availability. The attack vector is network-based, requiring no authentication, and has a low attack complexity.
The vulnerability was published on May 14, 2021, and is categorized under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'). Organizations using versions of the plugin prior to 2.1.0 are at risk.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly sanitize user input for the order_id parameter before it is used in SQL statements. Attackers may leverage this flaw to inject malicious SQL code into the database, which can lead to unauthorized data access, data manipulation, or even complete system compromise.
The attack vector is network-based, allowing exploitation over the internet. The attack complexity is low, as it does not require specialized knowledge or access. Additionally, no user interaction is necessary for the attack to succeed.
The vulnerability impacts confidentiality, integrity, and availability, making it a significant risk for organizations using the Car Seller - Auto Classifieds Script plugin.
