CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-31118 – Missing brute force protection on cloud federation sharing in Nextcloud Server
https://notcve.org/view.php?id=CVE-2022-31118
Nextcloud server is an open source personal cloud solution. In affected versions an attacker could brute force to find if federated sharing is being used and potentially try to brute force access tokens for federated shares (`a-zA-Z0-9` ^ 15). It is recommended that the Nextcloud Server is upgraded to 22.2.9, 23.0.6 or 24.0.2. Users unable to upgrade may disable federated sharing via the Admin Sharing settings in `index.php/settings/admin/sharing`.

CVSS: 5.4EPSS: 0%CPEs: 12EXPL: 2CVE-2022-31014 – SMTP Command Injection in iCalendar Attachments to emails via newlines in Nextcloud Server
https://notcve.org/view.php?id=CVE-2022-31014
Nextcloud server is an open source personal cloud server. Affected versions were found to be vulnerable to SMTP command injection. The impact varies based on which commands are supported by the backend SMTP server. However, the main risk here is that the attacker can then hijack an already-authenticated SMTP session and run arbitrary SMTP commands as the email user, such as sending emails to other users, changing the FROM user, and so on. As before, this depends on the configuration of the server itself, but newlines should be sanitized to mitigate such arbitrary SMTP command injection. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-264h-3v4w-6xh2 https://github.com/nextcloud/server/pull/32428 https://hackerone.com/reports/1516377 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection') •
