| Detailed Description |
According to its banner, the version of Apache running on the remote host is either 2.4.18 or 2.4.20. Additionally, HTTP/2 is enabled over TLS or SSL. It is, therefore, affected by the an authentication bypass vulnerability in the experimental module for the HTTP/2 protocol due to a failure to correctly validate X.509 certificates, allowing access to resources that otherwise would not be allowed. An unauthenticated, remote attacker can exploit this to disclose potentially sensitive information.
* Note: This check solely relied on the version number of the remote Web server to assess this vulnerability, so this might be a false positive.
