Trango Apex <= 2.1.1, ApexLynx < 2.0, ApexOrion < 2.0, ApexPlus <= 3.2.0, Giga <= 2.6.1, GigaLynx < 2.0, GigaOrion < 2.0, GigaPlus <= 3.2.3, GigaPro <= 1.4.1, StrataLink < 3.0, and StrataPro devices have a built-in, hidden root account, with a default password that was once stored in cleartext within a software update package on a Trango FTP server. This account is accessible via SSH and/or TELNET, and grants access to the underlying embedded UNIX OS on the device, allowing full control over it.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.
No commit or PR link among the references.
Credits

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Weakness class (CWE)
CWE-798 · Use of Hard-coded CredentialsCVSS vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Root cause
For convenience in support or manufacturing, an account that is identical on every device is embedded in the software. Credentials learned from one device work on all of them.
The bug in code
