critical Nessus Plugin ID 110264

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3665-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution
