Markoni-D (Compact) FM Transmitters: Improper Neutralization of Special Elements used in a Command
CVE-2024-39373 is a high-severity improper neutralization of special elements used in a command vulnerability in Markoni-D (Compact) FM Transmitters from marKoni, with a CVSS 3.1 base score of 7.2 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 2.0.1 as the first without the flaw, so updating Markoni-D (Compact) FM Transmitters to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.21% chance of exploitation within 30 days, higher than 69% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Markoni-D (Compact) FM Transmitters to 2.0.1 or a later version.
- Update Markoni-DH (Exciter+Amplifiers) FM Transmitters to 2.0.1 or a later version.
- Update markoni-d_fm_transmitter to 2.0.1 or a later version.

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.
