How the Exploit Works

The exploit works by leveraging the Incorrect Privilege Assignment vulnerability present in the ifkooo One-Login software. An attacker can manipulate this flaw to escalate their privileges within the system, potentially gaining unauthorized access to sensitive data or even taking control over the system. This vulnerability stems from a misconfiguration in the role and privilege assignment mechanism in ifkooo One-Login.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability. It’s important to note that this is a simplified example and actual exploitation might require a more complex approach.

POST /one-login/escalate HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "user_role": "admin", "current_privileges": "low", "desired_privileges": "high" }

In this example, the attacker is attempting to escalate their privileges from ‘low’ to ‘high’ by sending a POST request to the ‘/one-login/escalate’ endpoint.

Mitigation and Recommendations

To mitigate this vulnerability, it’s strongly recommended to apply the vendor patch as soon as it becomes available. In the meantime, utilizing Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. Regular monitoring and auditing of system logs can also aid in detecting any suspicious activity related to this vulnerability.
In addition, organizations should follow the principle of least privilege – granting only the minimum privileges necessary for any operation or process. Regular security assessments and updates are also crucial in maintaining a secure environment.
