CWE-116: Improper Encoding or Escaping of Output
Weakness ID : 116
Structure : Simple
Abstraction : Class
Description
The product prepares a structured message for communication with another component, but
encoding or escaping of the data is either missing or done incorrectly. As a result, the intended
structure of the message is not preserved.
Extended Description
Improper encoding or escaping can allow attackers to change the commands that are sent to
another component, inserting malicious commands instead.
Most products follow a certain protocol that uses structured messages for communication between
components, such as queries or commands. These structured messages can contain raw data
interspersed with metadata or control information. For example, "GET /index.html HTTP/1.1" is
a structured message containing a command ("GET") with a single argument ("/index.html") and
metadata about which protocol version is being used ("HTTP/1.1").
If an application uses attacker-supplied inputs to construct a structured message without properly
encoding or escaping, then the attacker could insert special characters that will cause the data to
be interpreted as control information or metadata. Consequently, the component that receives the
output will perform the wrong operations, or otherwise interpret the data incorrectly.
