CVE-2020-5216
Description
A directive injection vulnerability was found in Secure Headers RubyGem before versions 3.9.0, 5.2.0, and 6.3.0. If user-supplied input was passed into the vulnerable function, a new line could be injected, leading to limited header injection, which could create a new Content Security Policy header in the HTTP response.
Statement
Satellite 6 ships Secure Header rubygem, however, it does not accept any user input in override_content_security_policy_directive or append_content_security_policy_directive. All directives are hard-coded and therefor Satellite 6 is not vulnerable to this CVE. We may update this rubygem in 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).
