Summary

CVE-2022-23100 is a critical-severity OS Command Injection (CWE-78) vulnerability in Open-Xchange Ox App Suite. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 7.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

OX App Suite through version 7.10.6 is affected by an OS command injection vulnerability (CWE-78) in its Documentconverter component. The flaw carries a CVSS 3.1 base score of 9.8 and permits unauthenticated remote attackers to execute arbitrary operating-system commands, for example by sending a malicious email attachment that the converter processes.

An attacker needs only network access to the OX App Suite instance; no credentials or user interaction are required. Successful exploitation grants full confidentiality, integrity, and availability impact on the underlying system, allowing arbitrary command execution with the privileges of the converter process.

Public advisories and disclosure details are referenced at open-xchange.com and seclists.org/fulldisclosure/2022/Jul/11. The associated EPSS score has remained flat at 0.08 with no material increase since publication.
