Input Validation / Improper input validation

Description

Improper input validation occurs when an application does not adequately verify or sanitize the input it receives from users. This can lead to various security issues, such as injection attacks, buffer overflows, and cross-site scripting (XSS). When inputs are not properly validated, malicious actors can manipulate the input to execute unintended commands or access unauthorized data, compromising the application's integrity, confidentiality, and availability.

Risk

The risks associated with improper input validation are substantial. The attacks can result in data breaches, unauthorized access, data loss, and system downtime, leading to financial losses, reputational damage, and legal consequences.

Solution

Validate and sanitize all user input to minimize security risks, especially before passing the input to another application that may not be secured.
