How the Exploit Works

The exploit takes advantage of the vulnerability in the user vaults component of Devolutions Remote Desktop Manager. Under certain circumstances, when entries are edited by their owners, they may unintentionally be moved from user vaults to shared vaults. This makes the entries, which may contain sensitive personal information, accessible to other users, thereby violating privacy norms and potentially leading to data breaches.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited:

POST /user_vaults/edit_entry HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer <valid_user_token>
{
"entry_id": "sensitive_entry_123",
"new_vault_id": "shared_vault_456"
}

In the above example, a user with valid authentication credentials (represented by ``) sends a request to move a sensitive entry from their private vault to a shared vault. The server, failing to properly validate the request, executes the operation, inadvertently exposing the sensitive entry to unauthorized users.
