2) Input validation error
EUVDB-ID: #VU65831
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-2047
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient validation of user-supplied input when parsing invalid URIs such as http://localhost;/path. A remote attacker can pass specially crafted input to the application and bypass implemented security restrictions, as the Jetty's HttpClient, and Jetty's ProxyServlet / AsyncProxyServlet / AsyncMiddleManServlet will wrongly interpret an authority of such URI as the one with a hostname.

5) Insufficient Session Expiration
EUVDB-ID: #VU55642
Risk: Low
CVSSv3.1: 3.1 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-34428
CWE-ID:
CWE-613 - Insufficient Session Expiration
Exploit availability: No
DescriptionThe vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists due to insufficient session expiration issue. If an exception is thrown from the SessionListener#sessionDestroyed() method, then the session ID is not invalidated in the session ID manager. On deployments with clustered sessions and multiple contexts this can result in a session not being invalidated.

6) Information disclosure
EUVDB-ID: #VU51878
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-28163
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. If the ${jetty.base} directory or the ${jetty.base}/webapps directory is a symlink, the contents of the ${jetty.base}/webapps directory may be deployed as a static web application, exposing the content of the directory for download.
