Web Pentesting Injection Attacks

Web application penetration testing is an important process to identify security vulnerabilities in web applications. One of the most common types of vulnerabilities that can be exploited by attackers is injection attacks.

Injection attacks occur when untrusted data is sent to an interpreter as part of a command or query, causing unintended actions to be executed. The most common types of injection attacks are SQL injection, LDAP injection, and XML injection.

SQL Injection:

SQL injection attacks occur when untrusted data is inserted into SQL queries, causing the database to execute unintended commands. This can allow an attacker to view, modify, or delete data in the database. To prevent SQL injection attacks, developers should use parameterized queries or stored procedures, and validate user input.

LDAP Injection:

LDAP injection attacks occur when untrusted data is inserted into LDAP queries, causing the directory server to execute unintended commands. This can allow an attacker to view, modify, or delete directory information. To prevent LDAP injection attacks, developers should use parameterized queries or prepared statements, and sanitize user input.

XML Injection:

XML injection attacks occur when untrusted data is inserted into XML documents, causing the application to execute unintended commands. This can allow an attacker to view, modify, or delete sensitive data. To prevent XML injection attacks, developers should validate user input and use a secure XML parser.

In addition to the above, other types of injection attacks include OS command injection, code injection, and script injection. To prevent these types of attacks, developers should always validate user input, use parameterized queries or prepared statements, and sanitize input data. Web application penetration testing can help identify vulnerabilities in web applications and ensure that appropriate security measures are taken to prevent injection attacks.
