CVEID:   CVE-2021-28169
DESCRIPTION:   Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by a flaw in the ConcatServlet. By sending a specially-crafted request using a doubly encoded path, an attacker could exploit this vulnerability to obtain sensitive information from protected resources within the WEB-INF directory, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3

CVEID:   CVE-2021-34428
DESCRIPTION:   Eclipse Jetty could allow a physical attacker to bypass security restrictions, caused by a session ID is not invalidated flaw when an exception is thrown from the SessionListener#sessionDestroyed() method. By gaining access to the application on the shared computer, an attacker could exploit this vulnerability to bypass access restrictions.
CVSS Base score: 3.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/204227 for the current score.
CVSS Vector: (CVSS:3.0/AV:P/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)

CVEID:   CVE-2021-28163
DESCRIPTION:   Eclipse Jetty could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw when the ${jetty.base} directory or the ${jetty.base}/webapps directory is a symlink. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain webapp directory contents information, and use this information to launch further attacks against the affected system.
CVSS Base score: 2.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/199303 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N)

CVEID:   CVE-2021-28164
DESCRIPTION:   Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by improper input validation by the default compliance mode. By sending specially-crafted requests with URIs that contain %2e or %2e%2e segments, an attacker could exploit this vulnerability to access protected resources within the WEB-INF directory, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/199304 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:   CVE-2021-34429
DESCRIPTION:   Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by improper access control. By sending a specially-crafted URI, an attacker could exploit this vulnerability to obtain the content of the WEB-INF directory, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/205596 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:   CVE-2021-28165
DESCRIPTION:   Eclipse Jetty is vulnerable to a denial of service, caused by improper input valistion. By sending a specially-crafted TLS frame, a remote attacker could exploit this vulnerability to cause CPU resources to reach to 100% usage.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/199305 for the current score.
