Detailsinfo

A vulnerability was found in Langgenius Dify up to 1.14.x. It has been classified as critical. This affects the function make_request of the file /console/api/remote-files of the component Squid Proxy. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Dify before 1.15.0 contains a server-side request forgery vulnerability that allows any authenticated console user to bypass SSRF protections and issue arbitrary HTTP requests to internal services and cloud metadata endpoints due to the Squid proxy configuration only defining source ACLs without destination deny rules and the make_request() helper performing no independent destination IP validation. Attackers can use endpoints such as GET /console/api/remote-files/<url>, POST /console/api/remote-files/upload, the HTTP Request workflow node, website crawl, or document import from URL to reach internal components like the sandbox, internal APIs, and PostgreSQL, and on AWS deployments read IAM credentials from the instance metadata service, with the HTTP Request node further enabling POST, PUT, and DELETE writes to internal services relying on network isolation for authorization.
