There are different types of vulnerabilities that can be found in a web application during pentesting. Some of these include:
1. Cross-site scripting (XSS) – This vulnerability occurs when user input is not properly sanitized, allowing an attacker to inject malicious code into a web page. This code can then be executed by unsuspecting users who visit the page.
2. Injection vulnerabilities – These occur when user input is not properly filtered, allowing an attacker to inject malicious code into the application. This code can then be executed by the application to perform unauthorized actions.
3. Broken authentication and session management – This vulnerability occurs when the authentication and session management mechanisms of an application are not properly implemented. This can allow an attacker to gain access to resources or data that they should not have access to.
4. Insufficient logging and monitoring – This vulnerability occurs when an application does not properly log and monitor activity. This can allow an attacker to perform unauthorized actions without being detected.
5. Security misconfiguration – This vulnerability occurs when an application is not properly configured, resulting in a weak security posture. This can allow an attacker to exploit the application and gain access to sensitive data.
