The Fontsy WordPress plugin through 1.8.6 does not properly sanitize and escape a parameter before using it in a SQL statement via an AJAX action available to unauthenticated users, leading to a SQL injection.
This vulnerability allows attackers to execute arbitrary SQL queries, potentially leading to full database compromise. The severity level of this vulnerability is critical, with a CVSS score of 9.8. Organizations using this plugin are at significant risk if they do not implement the necessary patches.
Risk to organizations includes unauthorized access to sensitive data, data loss, and potential disruption of service. Attackers may leverage this vulnerability to manipulate database content or gain administrative control over affected WordPress sites.
Organizations should prioritize patching immediately. The vulnerability was published on January 16, 2023, and the exploitability status indicates that there are currently no known public exploits, but given the nature of SQL injection vulnerabilities, it is crucial to act quickly.
The urgency for remediation cannot be overstated, as the potential impact on business operations and security is profound.
Organizations should ensure that their WordPress installations and plugins are up to date and that proper security measures are implemented to prevent SQL injection attacks.
Vulnerability Details
The vulnerability is classified as a SQL injection, a common type of attack that involves injecting malicious SQL statements into an entry field for execution. The CVSS score is 9.8, indicating a critical severity level.
This affects the Fontsy plugin version 1.8.6 and earlier, and was discovered and reported in early 2023. The associated CWE classification is related to improper input validation.
Technical Analysis
The root cause of this vulnerability lies in the lack of proper parameter sanitization and escaping before SQL statements are executed by the plugin. This oversight allows attackers to manipulate SQL queries by injecting malicious payloads into the affected parameters.
The attack vector is network-based, meaning that attackers can exploit this vulnerability remotely without requiring physical access to the server. The attack complexity is low, and no privileges or user interaction are required to exploit this vulnerability.
The impacts are severe, with high confidentiality, integrity, and availability impacts due to the ability to execute arbitrary SQL commands. Organizations using the affected plugin should assess their exposure and take immediate action.
Risk & Impact Analysis
Real-world risks associated with this vulnerability are significant. Attackers can exploit this weakness to gain unauthorized access to sensitive data stored in the database, leading to potential data breaches and loss of customer trust.
The blast radius for this vulnerability is considerable, affecting all installations of the Fontsy plugin prior to version 1.8.7. Organizations must understand the implications of this vulnerability, especially those in industries that handle sensitive information.
Given the critical nature of this vulnerability, organizations should assess their patching strategies and prioritize remediation efforts based on the CVSS score and potential impact on operations.
Exploitation Status
