Modification of Assumed-Immutable Data (MAID)
- Description
The product does not properly protect an assumed-immutable element from being modified by an attacker.

- Common Consequences

Impact: Modify Application Data
Notes: Common data types that are attacked are environment variables, web application parameters, and HTTP headers.
