Moxa · Moxa Mgate 5105-Mb-Eip · CVE-2020-8858
Name of the Vulnerable Software and Affected Versions:
Moxa MGate 5105-MB-EIP version 4.1
Description:
The issue is related to the DestIP parameter in the Moxa MGate 5105-MB-EIP firmware, which lacks proper validation of user-supplied strings before executing system calls. This allows remote attackers to execute arbitrary code, potentially leading to privilege escalation. The exploitation requires authentication. The vulnerability is exploited through the `DestIP` parameter within the `MainPing.asp` endpoint.
Recommendations:
For version 4.1, consider restricting access to the `MainPing.asp` endpoint and the `DestIP` parameter to minimize the risk of exploitation until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
