How it was found

Hello Gents,

  • While testing eu2-cloud.acronis.com I found that read-only administrators are able to update agents just by editing the HTML!

Steps to reproduce:

  1. Please login at https://eu2-cloud.acronis.com/mc/
  2. From Users, invite a new user with Read-only administrator role.
  3. From Read-only administrator account navigate to "Agents Update" https://eu2-cloud.acronis.com/mc/app;group_id=*******/settings/agents-update
  4. Inspect element -> search for readonly.
  5. Change the value from readonly="true" to readonly="false".
  6. Edit, update and save.
  7. Now open the "Agents Update" page from the company administrator account, you will be able to see the changes!

Proof of concept:
