CVE-2020-26301
Description
A flaw was found in nodejs-ssh2. An OS command injection attack on Windows allows an attacker to perform remote code execution and potentially execute arbitrary code. The highest threat from this vulnerability is to confidentiality and integrity.
Statement
This issue affects ssh2 as shipped with all versions of Red Hat Openshift Container Storage and Red Hat Openshift Data Foundations. However, this flaw requires a Windows based attack, and therefore, the impact is adjusted accordingly to a moderate risk.
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).

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
