CVE-2020-14341
Description
A flaw was found in Red Hat Single Sign On. A test connection available on the application console can permit an authorized user to cause SMTP connections to be attempted to arbitrary hosts and ports of the user's choosing. By observing differences in the timings of these scans, an attacker may glean information about hosts and ports which they do not have access to scan directly. The highest threat from this vulnerability is to data confidentiality.
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.
