CVE-2021-38482Network attack vector

Session hijacking via stored management-site script

Published Oct 19, 2021 · Updated Sep 17, 2024

Stored XSS in InHand Networks InRouter615-S 2.3.0.r4724 and 2.3.0.r4870 allows remote authenticated users to hijack sessions. Public advisories do not identify the stored field or the missing output-neutralization operation that lets injected script persist in the management website. Administrative access is required to supply the payload; execution in another user's browser can expose or alter that user's session.
