DC 80: Use of Weak Credentials

Published Updated By the CyberSecBulletin desk

CVE-2026-22094 is a critical-severity use of weak credentials vulnerability in DC 80 from EVbee, with a CVSS 4.0 base score of 9.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.5.6 as the first without the flaw, so updating DC 80 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update DC 80 to 1.5.6 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The firmware for the EVbee DC-80 has a weak hardcoded root password, which allows attackers to login as root using the SSH daemon that is exposed to the network.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Use of Weak Credentials

The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.

How developers prevent this class of flaw

  • When the user changes or sets a password, check the password against a database of already compromised or breached passwords. These passwords are likely to be used in password guessing attacks.
