When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value.

Weakness classification

  • CWE-400: Uncontrolled Resource Consumption
  • CWE-1333: Inefficient Regular Expression Complexity
