Name of the Vulnerable Software and Affected Versions
NPort devices (affected versions not specified)
Description
Improper access control on the command port allows a remote attacker with network access to disrupt serial communication for an active user session. This occurs because the command interface fails to validate if a sender is associated with a valid data port session before accepting break signal commands, leading to a denial-of-service condition.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
