CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability is a high-priority SQL Injection flaw found in the WordPress Listdom Plugin versions 5.4.0 and below. It allows unauthenticated attackers to perform Blind SQL Injection, meaning they can send specially crafted SQL commands to the website's database without proper neutralization of special elements. This can enable attackers to interact directly with the database and potentially steal sensitive information.

Impact Analysis

The impact of this vulnerability is critical, with a CVSS score of 9.3. It allows attackers to access and extract sensitive data from the website's database without authentication. This can lead to data breaches, loss of confidential information, and potential disruption of services. The vulnerability is expected to be exploited in widespread attacks targeting thousands of websites.

Detection Guidance

This vulnerability is a Blind SQL Injection in the WordPress Listdom Plugin versions 5.4.0 and below, allowing unauthenticated attackers to interact with the database.

To detect this vulnerability on your system, you can monitor for unusual or suspicious HTTP requests targeting the Listdom plugin endpoints that may include SQL injection payloads.

While specific commands are not provided in the resources, common detection methods include using web application scanners or manual testing tools such as sqlmap to test for SQL injection vulnerabilities against the plugin's input fields.

Additionally, reviewing web server logs for anomalous query parameters or payloads that attempt to manipulate SQL queries can help identify exploitation attempts.

Mitigation Strategies

The immediate mitigation step is to update the WordPress Listdom Plugin to version 5.5.0 or later, where this SQL Injection vulnerability has been patched.

Until the update can be applied, Patchstack has issued a mitigation rule to block attacks targeting this vulnerability.

Users are also advised to seek assistance from their hosting provider or developer to implement temporary protections or apply the patch.

Compliance Impact

The SQL Injection vulnerability in the Listdom plugin allows unauthenticated attackers to access and potentially steal sensitive information from the website's database.

Such unauthorized access to sensitive data can lead to violations of data protection regulations like GDPR and HIPAA, which require the protection of personal and sensitive information against unauthorized disclosure.

Therefore, this vulnerability poses a significant risk to compliance with these common standards and regulations by potentially exposing confidential data.
