This vulnerability allows an attacker to manipulate cookie values by injecting malicious data into the query string or POST requests. This can lead to unintended consequences, such as session hijacking or stealing sensitive information.


To mitigate this risk, ensure that user-input cannot control cookie names and values. Implement input validation and sanitization to prevent semicolons from being used as name-value pair delimiters.
