Background
Graphite-web is a web application that provides a user interface for the Graphite time series database. It allows users to visualize and analyze data stored in the database. The vulnerable component, graphite-web/webapp/graphite/composer/views.py, contains a function called send_email. This function is responsible for sending emails through the SMTP server configured in Graphite. By default, the SMTP server is set to 'localhost'.
Vulnerability Detail
The send_email function in graphite-web/webapp/graphite/composer/views.py is vulnerable to Server-Side Request Forgery (SSRF). An attacker can exploit this vulnerability to make the Graphite web server request any resource on the network. The response from the SSRF request is then encoded into an image file and sent to an email address specified by the attacker. This allows the attacker to exfiltrate sensitive information from the target system.
