The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Start learningUpgrade rails
to version 2.3.3 or higher.
rails is an opensource MVC web framework.
Affected versions of this package are vulnerable to Improper Authentication. The example code for the digest authentication functionality http_authentication.rb
in Ruby on Rails before 2.3.3 defines an authenticate_or_request_with_http_digest
block that returns nil
instead of false
when the user does not exist, which allows context-dependent attackers to bypass authentication for applications that are derived from this example by sending an invalid username without a password.
