Error Messages

Not Applicable

Steps to Reproduce

  1. Log in to the application using the Pharmacist account.
  2. Click My Profile.
  3. Capture the request through the proxy interceptor.
  4. Modify the preActivityParams parameter in the request.
  5. Replace UserID%3Astgcallct with UserID%3Astgcallctrmgr. Manager profile displays with the user (Pharmacist) account.

Root Cause

The user name was sent as a parameter in the generated request making it susceptible to Cross-Site Scripting (XSS). As a result, the username was changed and details of other users was retrieved.
