CVE-2026-75112: OTTO® Fleet Manager – Weak Password Hashing Configuration
A security issue exists within OTTO® Fleet Manager. The vulnerability stems from the use of an insufficient work factor in the bcrypt password hashing implementation, which could reduce the computational cost required for an attacker to perform offline brute-force attacks against stored password hashes. If an attacker gains access to an unencrypted system backup, the weakly hashed credentials could be more easily compromised.

Frequently Asked Questions
Who is most exposed to this issue?
Organizations using OTTO Fleet Manager that store or retain unencrypted system backups are exposed if an attacker can obtain one of those backups. The issue concerns offline cracking of stored password hashes rather than direct remote authentication attacks.
What does an attacker need to exploit it?
An attacker needs access to an unencrypted system backup containing password hashes. They could then attempt offline brute-force attacks at a lower computational cost because the bcrypt work factor is insufficient.
What can be done while patching is not immediately possible?
Protect system backups from unauthorized access and ensure they are encrypted. Limiting access to backup storage reduces the opportunity for an attacker to obtain hashes for offline cracking.
