CVE-2024-43965 Scanner

SendGrid for WordPress is a popular plugin used to send emails through the SendGrid service via WordPress websites. Businesses and developers employ it to enhance email deliverability and manage transactional or marketing emails efficiently. The plugin is widely used by WordPress site administrators seeking simpler integration with SendGrid's email services. It provides users with a straightforward method to manage SMTP settings through the WordPress admin dashboard. Suitable for both small blogs and large enterprises, it aids in reliable email sending without needing complex server settings. The plugin eases the process of using SendGrid's comprehensive email tools within WordPress.

The vulnerability within this plugin involves SQL Injection, a critical issue that arises when an attacker can influence SQL queries made to a database. Unvalidated input fields in the application allow attackers to craft SQL commands that execute arbitrary database operations. Exploiting SQL Injection can lead to unauthorized data access, data modification, or destruction, compromising the site's integrity, confidentiality, and availability. Such vulnerabilities can be severe because they allow attackers to manipulate the database queries directly. SQL Injection can be exploited remotely without requiring any user privileges, making it a high-severity threat to web applications.

The vulnerability specifically affects the 'orderby' parameter in a particular GET request intended for admin logs. Attackers can exploit this by injecting SQL commands within the parameter, leading to arbitrary SQL command execution. This can be demonstrated through a 'sleep' command injection, causing delay-based testing to ascertain the presence of a SQLi flaw. The crafted input can manipulate how data gets fetched or sorted, potentially unveiling critical information in the process. Furthermore, the vulnerable endpoint inadvertently handles unsanitized input through its SQL statements. This can result in unexpected results such as information disclosure or database authentication bypass.

If exploited, this vulnerability could be highly damaging, leading to unauthorized data access and manipulation. Attackers might steal sensitive data such as user credentials or personal information. They might also modify or delete database entries, severely impacting website operations and reliability. Such manipulations can further pave the path for full system compromise if escalated appropriately. There's also the potential for corrupting backups if they rely on invalidated database inputs. Moreover, malicious exploitation may lead to significant reputational damage and legal implications for website owners.
