CVE-2021-29667

Remote command execution via CSV injection

Published Apr 27, 2021 · Updated Sep 16, 2024

IBM Spectrum Scale 5.0.0 through 5.1.0.2 allows remote attackers to execute arbitrary commands through CSV injection. The GUI improperly validates CSV fields, allowing attacker-controlled content to be interpreted as commands when CSV data is processed. Exploitation requires a crafted CSV supplied by an attacker and user interaction to open or process it, with command execution occurring on the cluster system.
