Description
UTMStack before 11.2.16 contains a server-side request forgery vulnerability in IdentityProviderService.validateMetadataUrl() that allows authenticated attackers to make the server send requests to arbitrary internal or cloud metadata hosts by supplying a malicious metadata URL to the identity-providers endpoint. Attackers can exploit the POST/PUT /api/identity-providers endpoint with no validation of target host, IP, or scheme to perform internal network port scanning and access cloud instance-metadata services.
