Package : graphite-web Version : 0.9.12+debian-6+deb8u1 CVE ID : CVE-2017-18638
The 'send_email' function in graphite-web/webapp/graphite/composer/views.py in Graphite is vulnerable to SSRF. The vulnerable SSRF endpoint can be used by an attacker to have the Graphite web server request any resource. The response to this SSRF request is encoded into an image file and then sent to an e-mail address that can be supplied by the attacker. Thus, an attacker can exfiltrate any information.
For Debian 8 "Jessie", this problem has been fixed in version 0.9.12+debian-6+deb8u1.
We recommend that you upgrade your graphite-web packages.
