CVE-2021-21330
Description
An open redirect flaw was found in python-aiohttp. This flaw allows a remote, unauthenticated attacker to trick users into visiting a malicious webpage, disguised as a legitimate webpage and affects applications using the normalize_path_middleware functionality. The highest threat from this vulnerability is to confidentiality and integrity.
Statement
Red Hat Satellite version 6.7 onward (mostly pulp part) does ship an affected version of aiohttp, however, is not vulnerable since the product code does not use the normalize_path_middleware function, which the attacker may use for an attack. We may update the python-aiohttp dependency in a future release.
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).
