WASC is proud to present a new WASC-article titled "The Unexpected SQL
Injection" by Alexander "Mordred" Andonov. This article surveys several
scenarios under which SQL injection may occur, even though
mysql_real_escape_string() has been used. There are two major steps at
writing SQL injection resistant code: correct validation and escaping of
input and proper use of the SQL syntax. Failure to comply with any of
them may lead to compromise. Many of the specific issues are already
known, but no single document mentions them all.
Although the examples in the paper make use of PHP/MySQL, the same
principles apply to ASP/MSSQL and other combinations of languages and
databases.
