SQL injection vulnerability in Node Vote 5.x before 5.x-1.1 and 6.x before 6.x-1.0, a module for Drupal, when "Allow user to vote again" is enabled, allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors related to a "previously cast vote."
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
