Successful exploitation of these vulnerabilities could result in an execution of arbitrary code.
The following versions of MACH SCM, are affected:
SCM Software is a client and server application. An Authenticated System manager client can execute LINQ query in the SCM server, for customized filtering. An Authenticated malicious client can send a specially crafted code to skip the validation and execute arbitrary code (RCE) on the SCM Server remotely. Malicious clients can execute any command by using this RCE vulnerability.
CVE-2024-0400 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2024-0400. A base score of 8.9 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L).
Authenticated List control client can execute the LINQ query in SCM Server to present event as list for operator. An authenticated malicious client can send special LINQ query to execute arbitrary code remotely (RCE) on the SCM Server that an attacker otherwise does not have authorization to do.
CVE-2024-2097 has been assigned to this vulnerability. A CVSS v3.1 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H ).
A CVSS v4 score has also been calculated for CVE-2024-2097. A base score of 8.8 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:H/SA:L).
Hitachi Energy reported these vulnerabilities to CISA.
Hitachi Energy has released the following mitigation for CVE-2024-2097:
Until the updates are made available, Hitachi Energy recommends the following general mitigation factors/workarounds for the products with MACH SCM Versions 4.0 to 4.5.x to address the vulnerability CVE-2024-0400:
Recommended security practices and firewall configurations can help protect a process control network from attacks originating from outside the network including:
