CVE-2026-75112OTTO® Fleet Manager – Weak Password Hashing Configuration
Medium 6.9
In plain English
A medium-severity security flaw in OTTO® Fleet Manager from Rockwell Automation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 6% of all known vulnerabilities).
Official description
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.
