Description
NextScan 1.1.0 through 1.2.0 contains a stored cross-site scripting vulnerability in the ns-admin URL asset detail dialog that renders crawled form request bodies (Asset_URL.data) via innerHTML without encoding. Attackers can host crafted forms on crawled sites to store JavaScript that executes when users view asset details, stealing localStorage access tokens to hijack sessions, including administrators.
