Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2022-2047)

The 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.


2) Resource management error (CVE-ID: CVE-2022-2048)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application when handling invalid HTTP/2 requests. A remote attacker can send specially crafted requests to the server and perform a denial of service (DoS) attack.


3) Improper access control (CVE-ID: CVE-2021-34429)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper input validation when processing certain characters in URI. A remote attacker can send a specially crafted HTTP request with encoded characters in URI, bypass implemented security restrictions and access content of the WEB-INF directory.
