Overview

CVE-2022-27226 is a high-severity vulnerability. It was published on March 19, 2022 and has a CVSS 3.1 base score of 8.8 (HIGH).

Technical description

A CSRF issue in /api/crontab on iRZ Mobile Routers through 2022-03-16 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
