Web Penetration Testing is a security evaluation method that simulates a cyber attack against a web application in order to identify vulnerabilities and assess the overall security of the application. The goal of web penetration testing is to identify any potential weaknesses in a web application that could be exploited by a malicious actor, and to provide recommendations for improving the security of the application.
There are several common vulnerabilities that can be found during a web penetration test, including:
- SQL Injection: A SQL injection attack is a type of attack where an attacker is able to inject malicious SQL code into a web application, allowing them to access or modify sensitive data stored in a database.
- Cross-Site Scripting (XSS): A XSS attack is a type of attack where an attacker is able to inject malicious script code into a web application, allowing them to steal user data or perform other malicious actions.
- Cross-Site Request Forgery (CSRF): A CSRF attack is a type of attack where an attacker is able to trick a user into performing an action on a web application, such as changing their password or transferring money.
- File Inclusion: A file inclusion vulnerability is a type of vulnerability that allows an attacker to include a file from a remote server or a local file system in a web page, which can be used to execute arbitrary code, read sensitive files, or perform other malicious actions.
- Broken Authentication and Session Management: Broken authentication and session management vulnerabilities occur when an application does not properly authenticate or manage user sessions, which can lead to unauthorized access and information leakage.
Here are some examples of tools and commands that can be used during web penetration testing:
- SQLMap: SQLMap is a tool for automating SQL injection attacks. It can be used to identify and exploit SQL injection vulnerabilities in web applications.
sqlmap -u "http://example.com/index.php?id=1" --dbs
- Burp Suite: Burp Suite is a tool for web application security testing. It can be used to identify and exploit a wide range of web application vulnerabilities, including XSS and CSRF.
burpsuite -repeater -url "http://example.com/index.php?id=1" -payload " <script>alert('XSS')</script>"
- OWASP ZAP: OWASP ZAP is a tool for web application security testing. It can be used to identify and exploit a wide range of web application vulnerabilities, including file inclusion vulnerabilities.
zap-cli --api-key 12345 --target "http://example.com" --scanners all --self-contained -g "sensitive_file_include"
- Wfuzz: Wfuzz is a tool for automating web application fuzz testing. It can be used to identify and exploit file inclusion vulnerabilities.
wfuzz -c -z file,/usr/share/wfuzz/wordlist/general/common.txt --hc 404 http://example.com/FUZZ
It’s important for organizations to conduct regular web penetration tests to identify and remediate vulnerabilities in their web applications. Web penetration testing should be conducted by experienced security professionals using the appropriate tools and techniques. The results of the penetration test should be used to improve the security of the web application and to prevent future attacks.
