CVE-2021-30175 Scanner

ZEROF Web Server, a lightweight and efficient web server software, is designed to serve web pages and manage web-based applications. The server is often chosen for its simplicity and low resource consumption, making it suitable for small to medium-sized web applications or personal projects. Despite its advantages, like any web server software, it requires diligent security practices to safeguard against potential vulnerabilities.

The vulnerability is triggered when an attacker sends specially crafted data to the /HandleEvent endpoint. This malicious data is improperly sanitized before being used in a SQL query, allowing the attacker to alter the structure of the SQL command and execute arbitrary SQL statements. This could lead to unauthorized access to sensitive information, modification of data, or even full database compromise.

Exploitation of this SQL Injection vulnerability can lead to severe consequences, including unauthorized access to sensitive data, modification or deletion of data, and potential compromise of the server hosting the ZEROF Web Server. The breach could also serve as a foothold for further attacks against the network infrastructure, leading to a broader security compromise.
