How to manually detect vulnerabilities in asp

asp manual detection of vulnerabilities: 1. Check the ASP application's verification and filtering mechanism for user input; 2. Check the ASP application's encoding and filtering mechanism for output data; 3. Check the ASP application's authentication and Session management mechanism; 4. Check the ASP application's permission control on files and directories; 5. Check the ASP application's handling of errors; 6. Check the ASP application's security of the database; 7. Check the configuration of the ASP application Files and server configuration.

Manual vulnerability detection is a method of discovering potential vulnerabilities by manually analyzing and testing ASP applications. The following are some commonly used manual vulnerability detection techniques and steps:

1. Input validation: Check the ASP application's validation and filtering mechanism for user input. Try entering special characters, long strings, SQL injection and XSS attacks, etc. and observe how the application responds and handles it.

2. Output encoding: Check the ASP application's encoding and filtering mechanism for output data. Try injecting malicious script or HTML tags and observe whether the application encodes and filters the output appropriately.

3. Authentication and session management: Check the authentication and session management mechanism of the ASP application. Observe application security and protection measures by attempting attacks such as authentication bypass, session hijacking, and session fixation.

4. File and directory permissions: Check the ASP application's permission control on files and directories. Attempt to access unauthorized files and directories and observe the application's access control and security.

5. Error handling: Check how the ASP application handles errors. Try triggering error conditions and observe the application's error handling mechanisms and information leakage.

6. Database security: Check the security of the ASP application to the database. Try a SQL injection attack and observe how the application handles and filters SQL queries.

7. Security configuration: Check the configuration file and server configuration of the ASP application. Ensure that no sensitive information is leaked in the configuration files and that the server configuration complies with best practices and security requirements.

It should be noted that manual vulnerability detection requires certain security knowledge and skills, and requires careful analysis and testing of all aspects of the application. In addition, manual vulnerability detection may produce false positives or misses, so it is recommended to combine automated scanning tools with other vulnerability detection methods to obtain more comprehensive and accurate results.
