Horizon Alert
Summary of the vulnerability and why it matters
An unauthenticated vulnerability in the MagicMirror² platform allows attackers to make the server send arbitrary HTTP requests. This could expose sensitive information or allow access to internal systems, as the platform also expands environment variables.
- Remote attackers can exploit this.
- Internal network access is a risk.
- Sensitive data exfiltration is possible.
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker can exploit the SSRF flaw in MagicMirror²'s `/cors` endpoint to make the server perform arbitrary HTTP requests. This allows them to target internal networks, cloud metadata services, or localhost, and potentially exfiltrate secrets by exploiting environment variable expansion.
- No authentication required.
- Targets internal network services.
- Exploits environment variables for secrets.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability is likely to be weaponized by attackers due to its unauthenticated Server-Side Request Forgery (SSRF) capabilities and the potential for secret exfiltration through environment variable expansion. These features allow attackers to probe internal networks and potentially gain access to sensitive information without any prior authentication.
- Unauthenticated SSRF for network pivoting.
- Environment variable expansion for secret exfiltration.
- Exploitable via network endpoint.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize immediate patching of MagicMirror² installations to version 2.36.0 or later to address the critical SSRF vulnerability, which allows unauthenticated remote attackers to execute arbitrary HTTP requests and exfiltrate secrets. If patching is delayed, implement network segmentation to isolate affected systems and block access to or from internal network resources.
- Update MagicMirror² to 2.36.0.
- Block suspicious outbound traffic.
- Monitor network activity for anomalies.
