CVE-2022-43699: Open-Xchange Ox App Suite

Medium severity, CVSS 4.3. EPSS: 0.5% chance of exploitation in the next 30 days.

OX App Suite before 7.10.6-rev30 allows SSRF because e-mail account discovery disregards the deny-list and thus can be attacked by an adversary who controls the DNS records of an external domain (found in the host part of an e-mail address).

Affected products

• Open-Xchange Ox App Suite: before 7.10.6 (fixed in 7.10.6); version 7.10.6 only
