Technical details have been disclosed regarding a number of security vulnerabilities affecting Moxa's MXview web-based network management system, some of which could be chained by an unauthenticated adversary to achieve remote code execution on unpatched servers.

The five security weaknesses "Could allow a remote, unauthenticated attacker to execute code on the hosting machine with the highest privileges available: NT AUTHORITYSYSTEM," Claroty security researcher Noam Moshe said in a report published this week.

"Successful exploitation of these vulnerabilities may allow an attacker to create or overwrite critical files to execute code, gain access to the program, obtain credentials, disable the software, read and modify otherwise inaccessible data, allow remote connections to internal communication channels, or interact and use MQTT remotely," the U.S. Cybersecurity and Infrastructure Security Agency said in an advisory.

MQTT refers to a messaging protocol that facilitates remote asynchronous communication, enabling the transfer of messages to and from different components in an MXview environment.

CVE-2021-38452 - A path traversal vulnerability in the application, allowing the access or overwrite of critical files used to execute code.

Three of the aforementioned flaws - CVE-2021-38452, CVE-2021-38454, and CVE-2021-38458, could be strung together to achieve pre-authenticated remote code execution on vulnerable MXView instances with SYSTEM privileges.
