CVE: CVE-2023-37788
Component: goproxy
CWE: CWE-400
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2023-07-18T00:00:00+00:00

A flaw was found in goproxy, which is vulnerable to a denial of service caused by improper input validation. This flaw allows a remote attacker can cause the goproxy server to crash by sending a specially crafted HTTP request to the HTTPS page, replacing the path "/" with an asterisk "*".

Statement: Goproxy is only susceptible to this vulnerability when used in MITM (Man In The Middle) mode. This use case is not relevant to any Red Hat products, so the impact is rated as Moderate.
