Post SMTP – WordPress SMTP Plugin with Email Logs and Mobile App for Failure Notifications – Gmail SMTP, Office 365, Brevo, Mailgun, Amazon SES and more Detection Scanner

The Post SMTP is a WordPress plugin designed to enhance email delivery by using reputable delivery services such as Gmail SMTP, Office 365, Brevo, Mailgun, and Amazon SES. It is widely used by WordPress administrators to ensure emails sent from their website reach recipients without being flagged as spam. The plugin is especially beneficial for businesses or websites that rely heavily on emailing functionalities like newsletters or customer communication. Furthermore, Post SMTP offers features such as email logging and mobile app notifications for delivery failures. The tool integrates seamlessly with WordPress, providing an intuitive interface for easy management. As a robust solution for email delivery, it is considered essential for WordPress site owners looking to maintain communication reliability.

The detected within this plugin is related to technology detection, allowing potential attackers to identify the use of this specific software on a website. Such detections can inform adversaries about the software stack, which might be leveraged in future targeted attacks, especially if any additional vulnerabilities are disclosed in Post SMTP or its dependencies. Identifying technology components helps attackers strategize their attack vectors effectively. Technology detection vulnerabilities are prevalent and pose risks, especially when leveraged alongside social engineering or other probing techniques. Awareness of identified technologies can thus indirectly increase the risk of exploitation in other linked components. Operators must consider concealing or obscuring technology use information to thwart easy reconnaissance.

The specific vulnerability details involve parsing of specific URL paths within the system to detect the use of the plugin. In this case, an HTTP GET request fetches the readme.txt file from the plugin directory, leveraging regex extraction methods to determine if specific characteristics indicative of the plugin version are present. These details are valuable in confirming the presence of the software, and to potentially detect if the version installed is outdated or not. This detection uses comparators to analyze version listings against known data repositories of software configurations. Although it serves an informational purpose, it indirectly points out precise site configurations that attackers may find valuable.

When such information is exploited, it could lead to increased security risks such as coordinated attacks against identified technology stacks or outdated versions being manipulated to gain unauthorized access. An attacker can strategize potential exploits by identifying specific software versions, allowing them to focus on known vulnerabilities in that release. The lack of technology obscurity ultimately makes it easier for attackers to collect intelligence about a target system, increasing the probability of successful exploits. This reinforces the importance of regular updates and the deployment of security patches across all recognized platforms.
