Additional Changes :

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.

According to the versions of the tomcat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The Realm implementations did not process the supplied     password if the supplied user name did not exist. This     made a timing attack possible to determine valid user     names. Note that the default configuration includes the     LockOutRealm which makes exploitation of this     vulnerability harder. (CVE-2016-0762)

  - It was discovered that a malicious web application     could bypass a configured SecurityManager via a Tomcat     utility method that was accessible to web applications.
    (CVE-2016-5018)

  - It was discovered that when a SecurityManager was     configured, Tomcat's system property replacement     feature for configuration files could be used by a     malicious web application to bypass the SecurityManager     and read system properties that should not be visible.
    (CVE-2016-6794)

  - It was discovered that a malicious web application     could bypass a configured SecurityManager via     manipulation of the configuration parameters for the     JSP Servlet. (CVE-2016-6796)

The version of Tomcat installed on the remote host is prior to 9.0.0.M10. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_9.0.0.m10_security-9 advisory.

  - The ResourceLinkFactory implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not limit web application access to global JNDI resources     to those resources explicitly linked to the web application. Therefore, it was possible for a web     application to access any global JNDI resource whether an explicit ResourceLink had been configured or     not. (CVE-2016-6797)

  - A malicious web application running on Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 was able to bypass a configured SecurityManager via     manipulation of the configuration parameters for the JSP Servlet. (CVE-2016-6796)

  - When a SecurityManager is configured, a web application's ability to read system properties should be     controlled by the SecurityManager. In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70, 6.0.0 to 6.0.45 the system property replacement feature for configuration files     could be used by a malicious web application to bypass the SecurityManager and read system properties that     should not be visible. (CVE-2016-6794)

  - In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to     6.0.45 a malicious web application was able to bypass a configured SecurityManager via a Tomcat utility     method that was accessible to web applications. (CVE-2016-5018)

  - The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user     name did not exist. This made a timing attack possible to determine valid user names. Note that the     default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.
    (CVE-2016-0762)

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

The version of Tomcat installed on the remote host is prior to 8.0.37. It is, therefore, affected by multiple vulnerabilities as referenced in the fixed_in_apache_tomcat_8.5.5_and_8.0.37_security-8 advisory.

  - The ResourceLinkFactory implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not limit web application access to global JNDI resources     to those resources explicitly linked to the web application. Therefore, it was possible for a web     application to access any global JNDI resource whether an explicit ResourceLink had been configured or     not. (CVE-2016-6797)

  - A malicious web application running on Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 was able to bypass a configured SecurityManager via     manipulation of the configuration parameters for the JSP Servlet. (CVE-2016-6796)

  - When a SecurityManager is configured, a web application's ability to read system properties should be     controlled by the SecurityManager. In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70, 6.0.0 to 6.0.45 the system property replacement feature for configuration files     could be used by a malicious web application to bypass the SecurityManager and read system properties that     should not be visible. (CVE-2016-6794)

  - In Apache Tomcat 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to     6.0.45 a malicious web application was able to bypass a configured SecurityManager via a Tomcat utility     method that was accessible to web applications. (CVE-2016-5018)

  - The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to     8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user     name did not exist. This made a timing attack possible to determine valid user names. Note that the     default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.
