🚨 Bug Bounty / Red Team Tip

CVE-2026-21643 — Critical Pre-Auth SQL Injection (CVSS 9.1) in FortiClient EMS 7.4.4 (multi-tenant mode only)

Unauthenticated attackers can inject arbitrary SQL via the Site HTTP header to the public endpoint /api/v1/init_consts (or login endpoint). This happens before authentication and hits the PostgreSQL backend with superuser-level access in many setups → full DB dump, schema extraction, or RCE (via PostgreSQL features like COPY FROM PROGRAM).

- Affected: Only FortiClient EMS 7.4.4 (multi-tenant/Sites feature enabled)
- Not affected: 7.2.x, 8.0.x, single-site deployments
- Fixed: Upgrade to 7.4.5 or later
- Status: Actively exploited in the wild + public PoCs available

Useful Google/Shodan Dorks:
- http.title:"FortiClient EMS" "7.4.4"
- http.html:"FortiClient Enterprise Management Server"
- http.favicon.hash: -specific-hash (or search for EMS login page)
- Shodan: "Model: FCTEMS" or "FortiClient EMS"

Quick Check:
If your EMS login page is internet-facing and running 7.4.4 with multi-tenant enabled → patch ASAP or block public access. Thousands of instances are exposed (Shadowserver ~2k+, Shodan ~1k+).

High-value target for hunters. Patch or restrict immediately!

Hey Hunters,

DarkShadow here back again!

out-of-scope target can lead to an in-scope critical vulnerability!
The story starts from a normal endpoint. When I clicked it, it redirected me somewhere else, and after resolving something, it returned the content. To check further what’s going on, I opened the request in Burp Suite. The endpoint performed a 302 redirect to an external domain, which was out of scope.

But here’s the twist—it was still showing the content from the original website I had requested. So I thought, maybe it’s working like a proxy?

Here comes the real mastery. Most bug hunters ignore this kind of behavior, but I decided to dig deeper. And yeah, I found a file: backup.zip
I instantly unzipped it and noticed a config/ folder, and inside it—a config.php file.

Guess what?
I found MySQL database credentials, and the most interesting part? The database URL was publicly accessible—not just localhost!

I tried connecting… and boom! I was successfully connected.
But wait—this domain is out of scope, right?

That’s what I thought too… until I started reading there massive database and was shocked—
It was the target's database, exposed through their proxy server, which had the hardcoded credentials in the config file.

At that moment, I was really excited.
Then I thought: What if I create a new user with admin role?
So I did exactly that—added an admin user to the database.

Now, on the target website, there’s a normal login page (not labeled as admin login), but I tried logging in with the new credentials and guess what?

BOOM! 💥
It logged me into the admin dashboard.

And just like that, I turned an out-of-scope target into a critical in-scope auth bypass vulnerability.✅


So guys, if you enjoyed this method, don’t forget to show some love—and please, pray for me, I’m really sick right now.
