Summary
Apache Tomcat could allow a remote attacker to bypass security restrictions
Vulnerability Details
CVE-ID: CVE-2017-5647
DESCRIPTION: Apache Tomcat could allow a remote attacker to obtain sensitive
information, caused by an error in the processing of pipelined requests in send
file. An attacker could exploit this vulnerability to obtain sensitive
information from the wrong response.
CVSS Base Score: 5.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
124400 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVE-ID: CVE-2017-5648
DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass security
restrictions, caused by the failure to use the appropriate facade object by
certain application listener calls. An attacker could exploit this
vulnerability to access and modify data on the system.
CVSS Base Score: 5.3
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
124399 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVE-ID: CVE-2017-5664
DESCRIPTION: Apache Tomcat could allow a remote attacker to bypass security
restrictions, caused by the improper handling of specific HTTP request methods
for static error pages by the Default Servlet error page mechanism. By sending
a specially crafted GET request, an attacker could exploit this vulnerability
to bypass HTTP method restrictions and cause the deletion or replacement of the
target error page.
CVSS Base Score: 6.5
CVSS Temporal Score: https://exchange.xforce.ibmcloud.com/vulnerabilities/
126962 for more information

CVEID: CVE-2017-7674
DESCRIPTION: Apache Tomcat could provide weaker than expected security, caused
by the failure to add an HTTP Vary header indicating that the response varies
depending on Origin by the CORS Filter. A remote attacker could exploit this
vulnerability to conduct client and server side cache poisoning.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
