New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote web server is affected by an HTTP redirect vulnerability.

Description

The version of IBM HTTP Server running on the remote host is affected by an HTTP redirect vulnerability related to Apache HTTP Server. The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an 'httpoxy' issue.

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

Solution

Upgrade to IBM HTTP Server version 7.0.0.43, 8.0.0.13, 8.5.5.11, 9.0.0.1, or later. Alternatively, upgrade to the minimal fix pack levels required by the interim fix and then apply Interim Fix PI73984.
