What are the potential consequences of successful command injection attacks on a web server?
Successful command injection attacks on a web server can have severe consequences, compromising the security and integrity of the system. Command injection is a type of vulnerability that allows an attacker to execute arbitrary commands on the server by injecting malicious input into a vulnerable application. This can lead to various potential consequences, including unauthorized
How can cookies be used as a potential attack vector in web applications?
Cookies can be used as a potential attack vector in web applications due to their ability to store and transmit sensitive information between the client and the server. While cookies are generally used for legitimate purposes, such as session management and user authentication, they can also be exploited by attackers to gain unauthorized access, perform
What are some common characters or sequences that are blocked or sanitized to prevent command injection attacks?
In the field of cybersecurity, specifically web applications penetration testing, one of the critical areas to focus on is preventing command injection attacks. Command injection attacks occur when an attacker is able to execute arbitrary commands on a target system by manipulating input data. To mitigate this risk, web application developers and security professionals commonly

What is the purpose of a command injection cheat sheet in web application penetration testing?
A command injection cheat sheet in web application penetration testing serves a important purpose in identifying and exploiting vulnerabilities related to command injection. Command injection is a type of web application security vulnerability where an attacker can execute arbitrary commands on a target system by injecting malicious code into a command execution function. The cheat
How can LFI vulnerabilities be exploited in web applications?
Local File Inclusion (LFI) vulnerabilities can be exploited in web applications to gain unauthorized access to sensitive files on the server. LFI occurs when an application allows user input to be included as a file path without proper sanitization or validation. This allows an attacker to manipulate the file path and include arbitrary files from
