Horizon Alert
Summary of the vulnerability and why it matters
An issue has been identified where an attacker could gain administrative access to an application if its default self-signed certificate is used. This occurs because the SSL certificate is used to sign authentication tokens, allowing an attacker to bypass login and potentially reconfigure the service or request logs. However, this vulnerability does not provide access to device credentials or customer data.
- Unauthenticated users can gain admin access.
- Default certificates enable bypass of logins.
- Confirm relevance, exposure, and default certificate use.
Attack Path
How an attacker could exploit the issue
An attacker can leverage the default self-signed certificate to bypass authentication and gain administrative control over the application. This is possible because the SSL certificate is used to sign authentication tokens, and if the default certificate is used, an attacker can forge these tokens to impersonate a legitimate administrator.
- Exposed to the network.
- Unauthenticated access to web interface.
- Administrative access to application.
Live Threat
Current exploitation, exposure, and threat context
When the default self-signed certificate is used, an attacker could gain administrative access to the application. This could allow them to configure the service or request log collection, but not access device credentials or customer data.
- Administrative access to the application.
- Bypassing login by signing JWT tokens.
- Unauthorized configuration or log requests.
Operational Fix
Recommended remediation, mitigation, and detection steps
The application owner is responsible for securing the web interface and managing its SSL certificates. The immediate first step is to identify all instances of the application, confirm their network exposure, and assess their criticality to business operations to prioritize remediation efforts.
- Identify and confirm application ownership.
- Verify network exposure and business criticality.
- Plan remediation based on assessed risk.
