"Improper input validation vulnerability in GOT2000 series GT27 model all versions, GOT2000 series GT25 model all
versions, GOT2000 series GT23 model all versions, GOT2000 series GT21 model all versions, GOT SIMPLE series GS21 model
all versions, and GT SoftGOT2000 all versions allows an remote unauthenticated attacker to write a value that exceeds
the configured input range limit by sending a malicious packet to rewrite the device value. As a result, the system
operation may be affected, such as malfunction.

"The following text was originally created by the Cybersecurity and Infrastructure Security Agency (CISA). The original
can be found at CISA.gov.

Mitsubishi Electric recommends users take measures such as installing a firewall to protect the GOT and system from
unauthorized access from external equipment via the network.

Mitsubishi Electric recommends users take the following mitigation measures to minimize the risk of exploiting this
vulnerability:

- Use a firewall or virtual private network (VPN), etc. to prevent unauthorized access when Internet access is required.
- Use the products within a LAN and block access from untrusted networks and hosts.
- Install antivirus software on user computers with access to the product and the system.
- Use the IP filter function to restrict the accessible IP addresses.

For more information, please contact the local Mitsubishi Electric representative or refer to the Mitsubishi Electric
support website.
