CVE-2022-37401
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.77%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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
