How to fix?

Upgrade RHEL:7 tomcat-el-2.2-api to version 0:7.0.54-8.el7_2 or higher.
This issue was patched in RHSA-2016:2046.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat-el-2.2-api package and not the tomcat-el-2.2-api package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Apache Tomcat 7.x through 7.0.70 and 8.x through 8.5.4, when the CGI Servlet is enabled, 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: the vendor states "A mitigation is planned for future releases of Tomcat, tracked as CVE-2016-5388"; in other words, this is not a CVE ID for a vulnerability.
