GENESIS64: Improper Neutralization of Special Elements used in an OS Command
CVE-2025-11774 is a high-severity improper neutralization of special elements used in an OS command vulnerability in GENESIS64 from Mitsubishi Electric, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected GENESIS64 versions: Version 10.97.2 CFR3 and prior. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.57% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of GENESIS64 you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on mitsubishielectric.com for workarounds and exact fixed builds.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the software keyboard function (hereinafter referred to as "keypad function") of Mitsubishi Electric GENESIS64 versions 10.97.2 CFR3 and prior, Mitsubishi Electric Iconics Digital Solutions GENESIS64 versions 10.97.2 CFR3 and prior, Mitsubishi Electric ICONICS Suite versions 10.97.2 CFR3 and prior, Mitsubishi Electric Iconics Digital Solutions ICONICS Suite versions 10.97.2 CFR3 and prior, Mitsubishi Electric MobileHMI versions 10.97.2 CFR3 and prior, Mitsubishi Electric Iconics Digital Solutions MobileHMI versions 10.97.2 CFR3 and prior, and Mitsubishi Electric MC Works64 all versions allows a local attacker to execute arbitrary executable files (EXE) when a legitimate user uses the keypad function by tampering with the configuration file for the function. This could allow the attacker to disclose, tamper with, delete, or destroy information stored on the PC where the affected product is installed, or cause a denial-of-service (DoS) condition on the system, through the execution of the EXE.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
