The Pricing Table WordPress plugin before 3.6.1 fails to properly sanitize and escape user supplied POST data before it is being interpolated in an SQL statement and then executed via an AJAX action available to unauthenticated users. This vulnerability allows attackers to inject malicious SQL code into the application.
With a CVSS score of 9.8, this vulnerability is classified as critical. The high severity indicates that the impact of exploitation could lead to severe consequences, including unauthorized data access, data manipulation, and service disruption.
Risk to organizations includes potential data breaches that may expose sensitive information, integrity compromises of database records, and overall system availability issues. Attackers may leverage this vulnerability to gain unauthorized access to the database and execute arbitrary commands.
Organizations should prioritize patching immediately. The vendor has released version 3.6.1 to address this issue. It's crucial for organizations using this plugin to apply the patch as soon as possible to safeguard against potential exploitation.
No public exploit has been confirmed for this vulnerability; however, the absence of known exploits does not lessen its severity or the necessity for immediate remediation.
Vulnerability Details
The vulnerability exists in the Pricing Table WordPress plugin prior to version 3.6.1. The lack of proper sanitization and escaping of user input in SQL statements can lead to SQL injection attacks. This vulnerability has a CVSS 3.1 score of 9.8, indicating a critical severity level.
The affected product is the Pricing Table plugin from ReputeInfoSystems, which is widely used in WordPress environments. The official description states that user-supplied POST data can be executed in an SQL statement without proper validation.
This flaw is classified under CWE-89, which pertains to improper neutralization of special elements used in an SQL command ('SQL Injection'). The vulnerability was published on May 16, 2022.
Technical Analysis
The root cause of this vulnerability lies in the inadequate sanitization of user inputs. Attackers can exploit this by sending crafted POST requests that manipulate SQL queries executed by the server. The attack vector is network-based, allowing remote attackers to target vulnerable installations.
The attack complexity is classified as low, as no special privileges are required to exploit this vulnerability. Additionally, user interaction is not necessary, making it easier for an attacker to exploit the flaw. The impacts of a successful exploitation include high confidentiality, integrity, and availability consequences.
Risk & Impact Analysis
Real-world deployment of this vulnerability can lead to unauthorized access to sensitive data stored in the database. The blast radius potential is significant due to the widespread use of the Pricing Table plugin across various WordPress sites. Organizations with this plugin installed are particularly vulnerable, as attackers may gain access to critical business information.
The urgency for addressing this vulnerability is high, as evidenced by its critical CVSS score and the potential for severe impacts. Organizations should assess their exposure and implement remediation strategies as part of their security posture.
