Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) 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

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

Update jetty9 package to version 9.4.39-3+deb11u1.

Vulnerable software versions

jetty9 (Debian package): before 9.4.39-3+deb11u1
