CVE-2022-43869Network attack vector

Authenticated GUI denial of service via format string

Published Feb 8, 2023 · Updated Mar 25, 2025

Format-string injection in IBM Spectrum Scale and IBM Storage Scale System allows remote authenticated users to interrupt the management GUI. The GUI processes attacker-controlled input as a formatting directive, but IBM has not disclosed the responsible endpoint, function, or resulting failure mode. An authenticated GUI account is required; affected ranges are Spectrum Scale 5.1.0.0 before 5.1.2.8 and 5.1.3.0 before 5.1.5.1, and Storage Scale System 6.1.0.0 before 6.1.2.4.
