Vulnerability Title
Chartbrew: DNS Rebinding SSRF Bypass in Outbound Request Validation
来源: CVE Program / CVE List V5
Vulnerability Description
Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.2, Chartbrew's server/modules/safeRequest.js calls validateOutboundUrl() to resolve and validate a target hostname, but request-promise performs a separate DNS resolution for the actual connection. An authenticated user who can create or test API connections and controls the target DNS name can return a public address during validation and a private address during the request, bypassing the protections implemented by server/modules/outboundTargetPolicy.js. This DNS rebinding condition can expose internal services, localhost resources, or cloud metadata endpoints. This issue is fixed in version 5.2.2.
