Understanding CVE-2023-5645

In the realm of cybersecurity, CVE-2023-5645 highlights a significant vulnerability in the WP Mail Log WordPress plugin prior to version 1.1.3. This vulnerability could potentially exploit SQL injection in the plugin's 'wml_logs' endpoint, allowing users with a role as low as Contributor to execute malicious SQL queries.

What is CVE-2023-5645?

CVE-2023-5645 is classified as a CWE-89 SQL Injection vulnerability. It arises from the inadequate sanitization and escape of a parameter used in an SQL statement within the WP Mail Log plugin. This flaw enables unauthorized users to manipulate the database by injecting malicious SQL queries.

The Impact of CVE-2023-5645

The impact of this vulnerability is significant as it can be leveraged by attackers with minimal privileges, such as Contributors, to execute arbitrary SQL commands. This could lead to data theft, modification, or deletion, posing a severe threat to the integrity and confidentiality of the affected WordPress websites.

Technical Details of CVE-2023-5645

Delving into the technical aspects of CVE-2023-5645 sheds light on the vulnerability description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description

The vulnerability in the WP Mail Log plugin stems from the lack of proper sanitization and escape mechanisms for user-supplied input, leaving the door open for SQL injection attacks. Attackers can exploit this weakness to alter database queries and potentially compromise the WordPress site's data.

Affected Systems and Versions

The CVE-2023-5645 vulnerability impacts WP Mail Log versions prior to 1.1.3. Specifically, versions below 1.1.3 are susceptible to SQL injection attacks through the 'wml_logs' endpoint.
