CVE-2020-26193

Authenticated OS command execution via improper input validation

Published Feb 9, 2021 · Updated Sep 16, 2024

Improper input validation in Dell PowerScale OneFS 8.1.0 through 9.1.0 allows remote authenticated users to execute OS commands via cluster management. Dell has not published the specific input field or operation that accepts untrusted data and reaches command execution. The ISI_PRIV_CLUSTER privilege is required, and successful exploitation runs commands with the vulnerable application's privileges, enabling confidentiality, integrity, and availability impact.
