The Fivestar module 6.x-1.x before 6.x-1.20 for Drupal does not properly validate voting data, which allows remote attackers to manipulate voting averages via a negative value in the vote parameter.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
