AK-SM8xxA Series: Improper Neutralization of Special Elements used in a Command
CVE-2025-41451 is a high-severity improper neutralization of special elements used in a command vulnerability in AK-SM8xxA Series from Danfoss, with a CVSS 4.0 base score of 8.7 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. The record lists version 4.3.1 as the first without the flaw, so updating AK-SM8xxA Series to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 4.46% chance of exploitation within 30 days, which is in the top 8.41% of all scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update AK-SM8xxA Series to 4.3.1 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when 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.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
