Debian LTS Advisory ([SECURITY] [DLA 1883-1] tomcat8 security update)

Published: 2019-08-14 02:00:17
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Summary:
The remote host is missing an update for the 'tomcat8' Linux Distribution Package(s) announced via the DSA-1883-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
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.

Affected Versions:
'tomcat8' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For Debian 8 'Jessie', these problems have been fixed in version 8.0.14-1+deb8u15. We recommend that you upgrade your tomcat8 Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
