As part of the fix for bug 61201, the documentation for Apache Tomcat 9.0.0.M22 to 9.0.1, 8.5.16 to 8.5.23, 8.0.45 to 8.0.47 and 7.0.79 to 7.0.82 included an updated description of the search algorithm used by the CGI Servlet to identify which script to execute. The update was not correct. As a result, some scripts may have failed to execute as expected and other scripts may have been executed unexpectedly. Note that the behaviour of the CGI servlet has remained unchanged in this regard. It is only the documentation of the behaviour that was wrong and has been corrected.

The version of Apache Tomcat installed on the remote host is < 7.0.84. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_7.0.84_security-7 advisory. Note that Nessus Network Monitor has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Apache Tomcat installed on the remote host is 9.0.x prior to 9.0.2. It is, therefore, affected by a flaw that is due to the program containing an incorrect description for the CGI Servlet search algorithm, which may cause an administrator to leave the system in an insecure state.

The version of Apache Tomcat installed on the remote host is version 8.5.x prior to 8.5.24. It is, therefore, affected by a flaw that is due to the program containing an incorrect description for the CGI Servlet search algorithm, which may cause an administrator to leave the system in an insecure state.

The version of Apache Tomcat installed on the remote host is version 8.0.45 prior to 8.0.48. It is, therefore, affected by a flaw that is due to the program containing an incorrect description for the CGI Servlet search algorithm, which may cause an administrator to leave the system in an insecure state.

The version of Apache Tomcat installed on the remote host is version 7.x prior to 7.0.84. It is, therefore, affected by a flaw that is due to the program containing an incorrect description for the CGI Servlet search algorithm, which may cause an administrator to leave the system in an insecure state.

The version of Apache Tomcat installed on the remote host is 7.0.x prior to 7.0.84. It is, therefore, affected by a flaw that is due to the program containing an incorrect description for the CGI Servlet search algorithm, which may cause an administrator to leave the system in an insecure state.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

It was discovered that Tomcat incorrectly handled being configured with HTTP PUTs enabled. A remote attacker could use this issue to upload a JSP file to the server and execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 17.10.
(CVE-2017-12616, CVE-2017-12617)

It was discovered that Tomcat contained incorrect documentation regarding description of the search algorithm used by the CGI Servlet to identify which script to execute. This issue only affected Ubuntu 17.10. (CVE-2017-15706)

It was discovered that Tomcat incorrectly handled en empty string URL pattern in security constraint definitions. A remote attacker could possibly use this issue to gain access to web application resources, contrary to expectations. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 17.10. (CVE-2018-1304)

It was discovered that Tomcat incorrectly handled applying certain security constraints. A remote attacker could possibly access certain resources, contrary to expectations. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 17.10. (CVE-2018-1305)

It was discovered that the Tomcat CORS filter default settings were insecure and would enable 'supportsCredentials' for all origins, contrary to expectations. (CVE-2018-8014).

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

This update for tomcat fixes the following issues :

Security issues fixed :

  - CVE-2018-1305: Fixed late application of security     constraints that can lead to resource exposure for     unauthorised users (bsc#1082481).

  - CVE-2018-1304: Fixed incorrect handling of empty string     URL in security constraints that can lead to unitended     exposure of resources (bsc#1082480).

  - CVE-2017-15706: Fixed incorrect documentation of CGI     Servlet search algorithm that may lead to     misconfiguration (bsc#1078677).

This update was imported from the SUSE:SLE-12-SP2:Update update project.

Incorrect documentation of CGI Servlet search algorithm may lead to misconfiguration :

As part of the fix for bug 61201, the documentation for Apache Tomcat included an updated description of the search algorithm used by the CGI Servlet to identify which script to execute. The update was not correct. As a result, some scripts may have failed to execute as expected and other scripts may have been executed unexpectedly. Note that the behaviour of the CGI servlet has remained unchanged in this regard. It is only the documentation of the behaviour that was wrong and has been corrected. (CVE-2017-15706)

Late application of security constraints can lead to resource exposure for unauthorised users :

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 authorised to access them. (CVE-2018-1305)

Incorrect handling of empty string URL in security constraints can lead to unintended exposure of resources :

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 unauthorised 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-2018-1304)
