CVE-2021-23283

Stored script execution via unvalidated resource input

Published Apr 19, 2022 · Updated Sep 17, 2024

Stored XSS in Eaton Intelligent Power Protector before 1.69 release 166 allows remote authenticated users to inject script via certain resources. IPP insufficiently validates input for those resources and improperly encodes it when rendering output, leaving stored markup executable. Administrative privileges and adjacent-network access are required; Eaton reports integrity impact and potential service interruption, but no confidentiality impact.
