  2. 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).

  3. 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.

  4. Security of the Java software platform - Wikipedia

    en.wikipedia.org/wiki/Security_of_the_Java...

    As with non-Java applications, security vulnerabilities can stem from parts of the platform which may not initially appear to be security-related. For example, in 2011, Oracle issued a security fix for a bug in the Double.parseDouble method. [2] This method converts a string such as "12.34" into the equivalent double-precision floating point ...

  5. Rainbow table - Wikipedia

    en.wikipedia.org/wiki/Rainbow_table

    To learn a password from a hash is to find a string which, when input into the hash function, creates that same hash. This is the same as inverting the hash function. Though brute-force attacks (e.g. dictionary attacks) may be used to try to invert a hash function, they can become infeasible when the set of possible passwords is large enough.

  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. Password cracking - Wikipedia

    en.wikipedia.org/wiki/Password_cracking

    Passwords were stored in cleartext in the database and were extracted through an SQL injection vulnerability. The Imperva Application Defense Center (ADC) did an analysis on the strength of the passwords. [22] Some of the key findings were: about 30% of users chose passwords whose length was below seven characters,

  8. 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.

  9. Category:Injection exploits - Wikipedia

    en.wikipedia.org/wiki/Category:Injection_exploits

    Injection exploits are computer exploits that use some input or data entry feature to introduce some kind of data or code that subverts the intended operation of the system. Usually these exploits exploit vulnerabilities resulting from insufficient data validation on input and so forth.
