Debian LTS Advisory ([SECURITY] [DLA 1301-1] tomcat7 security update)

Published: 2018-03-26 22:00:00
CVE Author: NIST National Vulnerability Database

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

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
tomcat7 on Debian Linux

Recommendations:
For Debian 7 'Wheezy', these problems have been fixed in version 7.0.28-4+deb7u18. We recommend that you upgrade your tomcat7 Linux Distribution Packages.

Summary:
Two security vulnerabilities have been discovered in the Tomcat servlet and JSP engine. CVE-2018-1304 The URL pattern of '' (the empty string) which exactly maps to the context root was not correctly handled in Apache Tomcat when used as part of a security constraint definition. This caused the constraint to be ignored. It was, therefore, possible for unauthorized users to gain access to web application resources that should have been protected. Only security constraints with a URL pattern of the empty string were affected. CVE-2018-1305 Security constraints defined by annotations of Servlets in Apache Tomcat were only applied once a Servlet had been loaded. Because security constraints defined in this way apply to the URL pattern and any URLs below that point, it was possible - depending on the order Servlets were loaded - for some security constraints not to be applied. This could have exposed resources to users who were not authorized to access them.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

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".
