Vulnerability from github – Published: 2026-08-19 21:30 – Updated: 2026-08-19 21:30

Details

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.

Severity

6.9 (Medium)
