AI Analysis
Technical Summary
Garlic-Hub, a digital signage management platform, contains an SSRF vulnerability (CWE-918) in versions before 1.1. Authenticated users can abuse the uploadFromUrl endpoint to force the server to perform arbitrary HTTP requests to internal network services. This allows attackers to conduct internal reconnaissance such as port scanning and service fingerprinting, and to retrieve internal HTTP responses which are then stored in a media pool accessible publicly. The issue is resolved in garlic-hub version 1.1.
Potential Impact
An attacker with authentication privileges can leverage this SSRF vulnerability to perform internal network reconnaissance, including port scanning and service fingerprinting, potentially exposing sensitive internal services. Additionally, internal HTTP responses can be retrieved and stored in a publicly accessible location, increasing the risk of information disclosure. There is no indication of direct code execution or denial of service from this vulnerability.
Mitigation Recommendations
Upgrade garlic-hub to version 1.1 or later, where this SSRF vulnerability has been patched. No other mitigation is specified or required once the update is applied.
