IRZ Mobile Routers Cross-Site Request Forgery (CVE-2022-27226)

high Tenable OT Security Plugin ID 502257


The remote OT asset is affected by a vulnerability.


A CSRF issue in /api/crontab on iRZ Mobile Routers through 20.6.1 allows a threat actor to create a crontab entry in the router administration panel. The cronjob will consequently execute the entry on the threat actor's defined interval, leading to remote code execution, allowing the threat actor to gain filesystem access. In addition, if the router's default credentials aren't rotated or a threat actor discovers valid credentials, remote code execution can be achieved without user interaction.

This plugin only works with Tenable.ot.
