Name of the Vulnerable Software and Affected Versions
Clair (affected versions not specified)
Description
A flaw in the fetcher component allows the system to make outbound HTTP requests to attacker-supplied URIs from manifest layer descriptors because it lacks IP or scheme filtering. When Pre-Shared Key (PSK) authentication is not configured, an unauthenticated attacker can submit a manifest with a URI pointing to internal services or cloud metadata endpoints, leading to Server-Side Request Forgery (SSRF). This SSRF is reflective for non-200 responses, which can leak up to 256 bytes of error body content through CheckResponse error messages. Operator-managed Red Hat Quay deployments are not affected as they auto-configure PSK.
Recommendations
Configure PSK authentication to prevent unauthenticated attackers from submitting manifests.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
