AI-suggested
Given the absence of official patches, organizations should implement immediate compensating controls. These include isolating mbCONNECT24 devices within segmented network zones with strict firewall rules limiting inbound access to trusted sources only. Employ network intrusion detection/prevention systems (IDS/IPS) to monitor and block suspicious command injection patterns targeting the com_mb24sysapi module. Disable or restrict remote management interfaces where possible. Conduct thorough input validation and sanitization on any custom integrations or scripts interfacing with mbCONNECT24. Regularly audit and monitor logs for unusual command execution or access attempts. Engage with MB connect line support for updates and apply patches promptly once available. Additionally, implement strong network-level authentication and VPN access controls to reduce exposure. Consider deploying application-layer firewalls or web application firewalls (WAFs) that can detect and block OS command injection attempts.
Description
Due to the improper neutralisation of special elements used in an OS command, an unauthenticated remote attacker can exploit an RCE vulnerability in the com_mb24sysapi module, resulting in full system compromise. This vulnerability is a variant attack for CVE-2020-10383.
