Debian DLA-1883-1 : tomcat8 security update (httpoxy)

critical Nessus Plugin ID 127865

Synopsis

The remote Debian host is missing a security update.

Description

Several minor issues have been fixed in tomcat8, a Java Servlet and JSP engine.

CVE-2016-5388

Apache Tomcat, 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. The 'cgi' servlet now has a 'envHttpHeaders' parameter to filter environment variables.

CVE-2018-8014

The defaults settings for the CORS filter provided in Apache Tomcat are insecure and enable 'supportsCredentials' for all origins. It is expected that users of the CORS filter will have configured it appropriately for their environment rather than using it in the default configuration. Therefore, it is expected that most users will not be impacted by this issue.

CVE-2019-0221

The SSI printenv command in Apache Tomcat echoes user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv command is intended for debugging and is unlikely to be present in a production website.

For Debian 8 'Jessie', these problems have been fixed in version 8.0.14-1+deb8u15.

We recommend that you upgrade your tomcat8 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
