How the Exploit Works

The Pixmeo Osirix MD Web Portal sends credential information in plain text over the network. An attacker could exploit this vulnerability by intercepting the network traffic between the user and the web portal. This could be achieved by launching a man-in-the-middle (MITM) attack or by sniffing network traffic on public WiFi networks. Once the attacker captures the unencrypted credentials, they can use them to gain unauthorized access to the system or leak the user’s sensitive data.

Conceptual Example Code

Below is a conceptual example of a network packet capture which contains the unencrypted credentials. An attacker could use a tool like Wireshark to intercept such network traffic:

GET /login HTTP/1.1
Host: target.example.com
Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ=
HTTP/1.1 200 OK
Content-Type: application/json
{ "token": "..." }

In the example above, “dXNlcm5hbWU6cGFzc3dvcmQ=” is a Base64 encoding of “username:password”. Since the credentials are transmitted in plain text, they could be easily decoded by an attacker.

Mitigation

Pixmeo has released a patch to address this vulnerability. Users are strongly advised to apply the patch immediately. As a temporary mitigation, users can also use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and filter network traffic. However, these measures only offer partial protection and cannot fully prevent the exploitation of this vulnerability.
