CVE-2021-38149Public exploitNetwork attack vector

Browser script execution via unsanitized user names

Published Aug 6, 2021 · Updated Aug 4, 2024

Stored XSS in Chikitsa Patient Management System 2.0.0 allows remote authenticated users to execute JavaScript in other users' browsers. The add-user route stores unsanitized payloads placed in user name fields and renders them whenever the resulting user entry is viewed. User-creation privileges and a later visit by another user are required, allowing attacker-controlled actions in that viewer's application context.
