CVE-2023-2744 : Exploit Details and Defense Strategies

This article discusses the details of CVE-2023-2744, focusing on a SQL Injection vulnerability in the WP ERP plugin version prior to 1.12.4.

Understanding CVE-2023-2744

This section provides an understanding of the CVE-2023-2744 vulnerability in the WP ERP plugin.

What is CVE-2023-2744?

CVE-2023-2744 refers to a SQL Injection vulnerability present in the WP ERP plugin before version 1.12.4. The vulnerability arises due to improper sanitization and escaping of the

type

parameter in the

erp/v1/accounting/v1/people

REST API endpoint. This flaw can be exploited by high privilege users, such as admin, to execute malicious SQL queries.

The Impact of CVE-2023-2744

The impact of CVE-2023-2744 is significant as it allows attackers with high privileges to manipulate the SQL database through the vulnerable

type

parameter. Exploitation of this vulnerability can lead to unauthorized data access, modification, or even deletion within the affected system.

Technical Details of CVE-2023-2744

This section delves into the technical aspects of CVE-2023-2744, covering vulnerability description, affected systems and versions, and the exploitation mechanism.

Vulnerability Description

The SQL Injection vulnerability in the WP ERP plugin version prior to 1.12.4 stems from the inadequate sanitization and escaping of user-supplied input in the

erp/v1/accounting/v1/people

REST API endpoint. This oversight allows high privilege users to inject and execute malicious SQL queries, potentially compromising the integrity and confidentiality of the database.

Affected Systems and Versions

The affected system is the WP ERP plugin, specifically versions below 1.12.4. Users using versions earlier than 1.12.4 are susceptible to the SQL Injection vulnerability if the

erp/v1/accounting/v1/people

API endpoint is exposed.

Exploitation Mechanism

The exploitation of CVE-2023-2744 involves crafting malicious SQL queries and injecting them through the vulnerable

type

parameter in the

erp/v1/accounting/v1/people

endpoint. By exploiting this vulnerability, threat actors can manipulate the database and gain unauthorized access to sensitive information.

Mitigation and Prevention

This section outlines the mitigation steps to address CVE-2023-2744 and prevent potential exploitation of the SQL Injection vulnerability in the WP ERP plugin.

Immediate Steps to Take

Users are advised to update their WP ERP plugin to version 1.12.4 or later to mitigate the SQL Injection vulnerability. Additionally, restricting access to the

erp/v1/accounting/v1/people

endpoint and implementing input validation can help prevent exploitation.

Long-Term Security Practices

Implementing secure coding practices, conducting regular security audits, and staying informed about plugin updates and security advisories can enhance the long-term security posture of WordPress installations.

Patching and Updates

Regularly monitoring for plugin updates and promptly applying patches released by the plugin vendor is crucial in addressing known vulnerabilities like CVE-2023-2744. Stay vigilant and ensure that all plugins are kept up to date to mitigate potential security risks.
