CVEID: CVE-2016-6796
DESCRIPTION: Apache Tomcat could allow a local attacker to bypass security restrictions. By modifying configuration parameters for the JSP Servlet, an attacker could exploit this vulnerability to bypass a configured SecurityManager.
CVSS Base Score: 4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/118404 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2016-6797
DESCRIPTION: Apache Tomcat could allow a local attacker to gain unauthorized access to the system, caused by an error in the ResourceLinkFactory. An attacker could exploit this vulnerability to gain access to arbitrary global JNDI resources.

CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2016-6816
DESCRIPTION: Apache Tomcat is vulnerable to HTTP response splitting attacks, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability to inject arbitrary HTTP headers and cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning or cross-site scripting, and possibly obtain sensitive information.
