TOUCHSCREENS x70: Improper Neutralization of Argument Delimiters in a Command
CVE-2025-47421 is a high-severity improper neutralization of argument delimiters in a command vulnerability in TOUCHSCREENS x70 from Crestron, with a CVSS 4.0 base score of 8.6 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 3.001.0034.001 as the first without the flaw, so updating TOUCHSCREENS x70 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.38% 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
- Update TOUCHSCREENS x70 to 3.001.0034.001 or a later version.

Official description
Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in CRESTRON TOUCHSCREENS x70 allows Argument Injection.This issue affects TOUCHSCREENS x70: from 3.001.0031.001 through 3.001.0034.001. A specially crafted SCP command sent via SSH login string can lead a valid administrator user to gain Privileged Operating System access on the device. Following Products Models are affected: TSW-x70 TSW-x60 TST-1080 AM-3000/3100/3200 Soundbar VB70 HD-PS622/621/402 HD-TXU-RXU-4kZ-211 HD-MDNXM-4KZ-E *Note: additional firmware updates will be published once made available

The underlying weakness: Improper Neutralization of Argument Delimiters in a Command
The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.
How developers prevent this class of flaw
- Understand all the potential areas where untrusted inputs can enter your product: parameters or arguments, cookies, anything read from the network, environment variables, request headers as well as content, URL components, e-mail, files, databases, and any external systems that provide data to the application. Perform input validation at well-defined interfaces.
- Directly convert your input type into the expected data type, such as using a conversion function that translates a string into a number. After converting to the expected data type, ensure that the input's values fall within the expected range of allowable values and that multi-field consistencies are maintained.
- When exchanging data between components, ensure that both components are using the same character encoding. Ensure that the proper encoding is applied at each interface. Explicitly set the encoding you are using whenever the protocol allows you to do so.
