NT OneAPP: Hard-coded cryptographic key enables decryption of login requests
Summary
NT OneAPP, an enterprise management app from NewType Infortech, contains a hard-coded cryptographic key. An unauthenticated remote attacker who obtains this key can decrypt login requests and recover users' plaintext account credentials and device information. The attack requires the attacker to be able to observe or intercept the app's network traffic, and the CNA rates the attack complexity as high.
Affected
- NT OneAPP versions 0 to 1.5.22 (per CNA record)
Fixed in
- Update to NT OneAPP version 1.5.35 or later (per CNA record; not yet confirmed by TWCERT or the vendor)
- Unknown: whether fixed builds exist for all platforms (Android, iOS, PC emulator)
Workaround
Unknown.
Exploitation
- CISA SSVC: exploitation none, automatable no, technical impact total
- No evidence of exploitation in the wild found
- No public proof of concept found
- EPSS 0.0034 (very low)
Our recommendation
- Inventory all NT OneAPP installations and their versions
- Update to the fixed version as soon as TWCERT or the vendor confirms it
- After updating, have users reset passwords for their NewType accounts and any shared credentials entered in the app
- Avoid using the app over public or untrusted Wi-Fi until patched
- Review related CVE-2026-114220 (certificate validation flaw enabling man-in-the-middle attacks) and patch together with this issue
