String interpolation, like string concatenation, may lead to security problems. If user input data is improperly escaped or filtered, the system will be exposed to SQL injection, script injection, XML external entity (XXE) injection, and cross-site scripting (XSS) attacks. [4] An SQL injection example: query = "SELECT x, y, z FROM Table WHERE ...
If the URL may contain equal signs, the parameters should be numbered explicitly to have the template work as expected (otherwise, parameter value overrides may occur) ; this is more problematic when an explicit display text is provided in parameter 2.
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.
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).
A query string is a part of a uniform resource locator that assigns values to specified parameters.A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.
Double URI-encoding, also referred to as double percent-encoding, is a special type of double encoding in which data is URI-encoded twice in a row. [6] In other words, double-URI-encoded form of data X is URI-encode(URI-encode(X)). [7]
A URI Template is a way to specify a URI that includes parameters that must be substituted before the URI is resolved. It was standardized by RFC 6570 in March 2012. The syntax is usually to enclose the parameter in Braces ({example}). The convention is for a parameter to not be Percent encoded unless it follows a Question Mark (?).
The example attack consists of defining 10 entities, each defined as consisting of 10 of the previous entity, with the document consisting of a single instance of the largest entity, which expands to one billion copies of the first entity. In the most frequently cited example, the first entity is the string "lol", hence
