Moxa’s Response Regarding the networkd-dispatcher (D-bus) Elevation of Privileges Linux Vulnerability, Nimbuspwn (CVE-2022-29799, CVE-2022-29800)

There are two vulnerabilities in networkd-dispatcher. One vulnerability exists because no functions are sanitized by the OperationalState or the AdministrativeState of networkd-dispatcher. This attack leads to a directory traversal to escape from the “/etc/networkd-dispatcher” base directory. Another vulnerability known as, time-of-check-time-of-use (TOCTOU) race condition, exists because there is a certain time between the scripts being discovered and them being run. An attacker can take advantage of this vulnerability to replace scripts that networkd-dispatcher believes to be owned by root with scripts that are not.

Moxa is investigating to determine if any of our products are affected by this vulnerability. At the time of publication, none of Moxa’s products are affected.

Moxa's Product Security Incident Response Team (PSIRT) will keep monitoring the situation and if there are any updates to the status of the vulnerability that affects Moxa's products, we will provide an update immediately.

Moxa is investigating the vulnerability and has determined that none of our products are currently affected.
