  2. Code injection - Wikipedia

    en.wikipedia.org/wiki/Code_injection

    An SQL injection takes advantage of SQL syntax to inject malicious commands that can read or modify a database or compromise the meaning of the original query. [13] For example, consider a web page that has two text fields which allow users to enter a username and a password.

  3. SQL injection - Wikipedia

    en.wikipedia.org/wiki/SQL_injection

    A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).

  4. Prepared statement - Wikipedia

    en.wikipedia.org/wiki/Prepared_statement

    Major DBMSs, including SQLite, [5] MySQL, [6] Oracle, [7] IBM Db2, [8] Microsoft SQL Server [9] and PostgreSQL [10] support prepared statements. Prepared statements are normally executed through a non-SQL binary protocol for efficiency and protection from SQL injection, but with some DBMSs such as MySQL prepared statements are also available using a SQL syntax for debugging purposes.

  5. Brute-force attack - Wikipedia

    en.wikipedia.org/wiki/Brute-force_attack

    When password-guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search takes too long. Longer passwords, passphrases and keys have more possible values, making them exponentially more difficult to crack than shorter ones ...

  6. Salt (cryptography) - Wikipedia

    en.wikipedia.org/wiki/Salt_(cryptography)

    It is common for a web application to store in a database the hash value of a user's password. Without a salt, a successful SQL injection attack may yield easily crackable passwords. Because many users re-use passwords for multiple sites, the use of a salt is an important component of overall web application security. [14]

  7. Pass the hash - Wikipedia

    en.wikipedia.org/wiki/Pass_the_hash

    If an attacker has the hashes of a user's password, they do not need the cleartext password; they can simply use the hash to authenticate with a server and impersonate that user. [4] [5] [6] In other words, from an attacker's perspective, hashes are functionally equivalent to the original passwords that they were generated from.

  8. File inclusion vulnerability - Wikipedia

    en.wikipedia.org/wiki/File_inclusion_vulnerability

    A file inclusion vulnerability is a type of web vulnerability that is most commonly found to affect web applications that rely on a scripting run time.This issue is caused when an application builds a path to executable code using an attacker-controlled variable in a way that allows the attacker to control which file is executed at run time.

  9. Password cracking - Wikipedia

    en.wikipedia.org/wiki/Password_cracking

    The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file ...
