How I Hacked Samsung's Tizen OS & LG Electronics Private Project Management Instances

Introduction

Months ago I discovered a flaw hackers can use to access Samsung’s and LG Electronics internal bug tracking and project management instances running on Jira. The flaw only takes a couple of commands to potentially access intranets, cause XSS and anything that SSRF can cause, including something such as,

https://public.example.com/proxy?url=admin-panel.example.com

The bug is still out there. I reported the vulnerability, and the usual BS followed which has led me to write this blog.

Usual Boring SSRF, Right?

Umm, I guess you're right, pinging google.com is not cool, neither is causing XSS (right?).

When discovered on a cloud instance though, things get a little more interesting as attackers can access the metadata instance, available via an APIPA range IP address over HTTP— http://169.254.169.254/, and accessible only from the target.

Samsung's Tizen OS Bug Tracking Dashboard

In the process of researching a performance bug of Tizen OS (tizen.org), I came to know about https://bugs.tizen.org. The dashboard over https://bugs.tizen.org/secure/Dashboard.jspa has a severe SSRF vulnerability.

Proof of concept for XSS

Using an image metadata editor I altered EXIF metadata and crafted a malicious SVG which led to XSS.

The payload was,

<svg xmlns="http://www.w3.org/2000/svg" onload="alert(document.domain)"/>

Using Jiraffe, I was able to quickly find that the server is hosted over Amazon AWS (fucking Bezos!) and was able to … well, I immediately stopped all testing as I didn’t want to break any rules of engagement, quickly sending in a report about my findings.

Yeah.

LG CNS

Google it. I'm not gonna deep dive into how big LG actually is.

I actually am not going to disclose the domain or the bug exactly because they sent an email just recently,

--REDACTED--

As we said, LG CNS is a separate company from us.
Thus, we don't also have a contact point.
We'll contact the relevant department.
Thank you.

Best Regards,
LG PSRT.

I will probably update the blog once the issue is resolved.
