2) Input validation error

EUVDB-ID: #VU65831

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-2047

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Jetty: 9.0.0.v20130308 - 11.0.9

Exploit availability: No

Description

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