Apache 2.4.x < 2.4.54 Authentication Bypass

critical Nessus Plugin ID 193421

Language:

Synopsis

The remote web server is affected by an authentication bypass vulnerability.

Description

The version of Apache httpd installed on the remote host is prior to 2.4.54. It is, therefore, affected by an authentication bypass vulnerability as referenced in the 2.4.54 advisory.

 - X-Forwarded-For dropped by hop-by-hop mechanism in mod_proxy: Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on the origin server/application.
 Acknowledgements: The Apache HTTP Server project would like to thank Gaetan Ferry (Synacktiv) for reporting this issue

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache version 2.4.54 or later.
