Web pages are categorized as static or dynamic. To understand these, we must first differentiate between servers and clients. A server is a device running server software that provides services like web browsing and database queries to clients. Conversely, a client, using software such as a browser,...
Command injection vulnerabilities occur when an application passes unsafe user input directly to a shell command interpreter. This allows an attacker to execute arbitrary commands on the host operating system, typically with the privileges of the vulnerable application. A Basic Example of a Vulnerab...
