CVE-2021-38468Network attack vector

Session hijacking via stored script injection

Published Oct 19, 2021 · Updated Sep 16, 2024

Stored cross-site scripting in InHand Networks InRouter615-S 2.3.0.r4724 and 2.3.0.r4870 allows remote authenticated users to hijack sessions. Public advisories identify the web management interface but do not disclose the input field, storage path, or output context that fails to neutralize script content. A remote authenticated user must store a payload that is later rendered in a connected user session; the reported consequence is session hijacking.
