# CVE-2022-37401: Apache OpenOffice Weak Master Keys

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 4.1.13
- Published: 2022-08-13 · Updated: 2024-08-03

## Affected

- Apache Software Foundation Apache OpenOffice: from Apache OpenOffice 4, fixed in 4.1.13

## Description

Apache OpenOffice supports the storage of passwords for web connections in the user's configuration database. The stored passwords are encrypted with a single master key provided by the user. A flaw in OpenOffice existed where master key was poorly encoded resulting in weakening its entropy from 128 to 43 bits making the stored passwords vulnerable to a brute force attack if an attacker has access to the users stored config. This issue affects: Apache OpenOffice versions prior to 4.1.13. Reference: CVE-2022-26307 - LibreOffice
