Improper Access Control in Apache Tomcat

High severity GitHub Reviewed Published May 13, 2022 to the GitHub Advisory Database • Updated Feb 22, 2024

Package

maven org.apache.tomcat:tomcat-catalina (Maven)

Affected versions

>= 7.0.0, < 7.0.72
>= 8.0.0, < 8.5.5

Patched versions

7.0.72
8.5.5

Description

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.
