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).
documentconverter in OX App Suite through 7.10.6, in a non-default configuration with ghostscript, allows OS Command Injection because file conversion may occur for an EPS document that is disguised as a PDF document.
OX App Suite through 7.10.6 allows SSRF because multipart/form-data boundaries are predictable, and this can lead to injection into internal Documentconverter API calls.
