MonitorCVSS 6.8ICS-CERT ICSA-26-239-03Aug 19, 2026
Rockwell Automation
Summary

OTTO Fleet Manager uses weak password hashing configuration in its user authentication system. This allows an attacker who gains access to the application database to crack user passwords offline, potentially leading to unauthorized access and control of the autonomous mobile robot fleet.

What this means
What could happen
An attacker with access to the OTTO Fleet Manager database could crack user passwords due to weak hashing, potentially gaining unauthorized access to the fleet management system and the autonomous mobile robots it controls.
Who's at risk
Operators and managers of Rockwell Automation OTTO autonomous mobile robot fleets who use the OTTO Fleet Manager application for fleet oversight and command. This affects organizations in warehousing, manufacturing, logistics, and materials handling that depend on robot fleet availability and correct operation.
How it could be exploited
An attacker with database access (either through a separate vulnerability, misconfigured backup, or stolen database file) can extract password hashes from OTTO Fleet Manager. Because weak hashing is used, passwords can be cracked offline using readily available tools, allowing the attacker to log in as a legitimate user and command the fleet.
Prerequisites
  • Access to the OTTO Fleet Manager database or backups
  • Ability to extract password hashes from the database
