Critical

Unauthenticated RCE in MB CONNECT LINE com_mb24sysapi

IdentifiersCVE-2020-10383CWE-78

CVE-2020-10383 affects MB CONNECT LINE mymbCONNECT24 and mbCONNECT24 software in all versions through 2.5.0. The issue is an unauthenticated remote code execution vulnerability in the com_mb24sysapi module. The provided context indicates a related variant is an OS command injection flaw caused by improper neutralization of special elements used in an OS command, which supports classifying this issue as CWE-78. Successful exploitation allows a remote attacker to execute arbitrary commands on the affected system.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An unauthenticated remote attacker can achieve remote code execution against affected systems. Given the nature of the flaw and the related context describing full system compromise, exploitation can result in complete compromise of the target, including loss of confidentiality, integrity, and availability.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict network exposure to the affected service and module, especially from untrusted networks. Limit access using firewall rules, VPN allowlists, segmentation, and administrative access controls. Monitor for suspicious requests targeting the com_mb24sysapi module and for signs of command execution on the host. Because the vulnerability is unauthenticated and remotely reachable, reducing exposure is the primary mitigation until a fixed version is installed.

Remediation

Patch, then assume compromise.

Upgrade from affected versions of mymbCONNECT24 and mbCONNECT24. The provided context states that all versions through 2.5.0 are affected, so remediation requires deploying a vendor-fixed version later than 2.5.0 if available. Apply any MB CONNECT LINE or CERT VDE security advisories and patches relevant to this issue.
