CVE-2022-41969: Nextcloud Server

Low severity, CVSS 2.7. EPSS: 0.9% chance of exploitation in the next 30 days.

Nextcloud Server is an open source personal cloud server. Prior to versions 23.0.11, 24.0.7, and 25.0.0, there is no password length limit when creating a user as an administrator. An administrator can cause a limited DoS attack against their own server. Versions 23.0.11, 24.0.7, and 25.0.0 contain a fix for the issue. As a workaround, don't create user accounts with long passwords.

Affected products

• Nextcloud Nextcloud Server: from 23.0.0, before 23.0.11 (fixed in 23.0.11); from 24.0.0, before 24.0.7 (fixed in 24.0.7)
