CVE-2022-39348
Description
A host header injection flaw was found in the twisted event-based framework's web module. When the host header does not match a configured host, the web module will render unescaped characters into the 404 response. This can result in HTML and script injection. For this vulnerability to be exploited, the attacker needs to be in a privileged position.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
