Low risk19th percentile - higher than 19% of all known CVEs
Summary
In Red Hat Quay, when SECURITY_SCANNER_V4_PSK is not set, a remote unauthenticated attacker can send POST requests to the security scanner notification endpoint, allowing flooding of the notification queue and injection of path traversal characters into Clair API URL paths.
Risk Assessment
The primary consequence is worker resource exhaustion and blind path manipulation on the configured Clair host, potentially leading to denial of service.
Recommendation
Set a strong SECURITY_SCANNER_V4_PSK and restrict access to the notification endpoint.
Original NVD description (English source)
A flaw was found in Red Hat Quay. When the SECURITY_SCANNER_V4_PSK (pre-shared key) is not set, a remote unauthenticated attacker can send POST requests to the security scanner notification endpoint. This allows the attacker to flood the notification queue and inject path traversal characters into Clair API URL paths. The primary consequence is worker resource exhaustion and blind path manipulation on the configured Clair host, potentially leading to a denial of service.
