Official description

Cleartext transmission of sensitive information vulnerability exists in STARDOM FCN Controller and FCJ Controller R1.01 to R4.31, which may allow an adjacent attacker to login the affected products and alter device configuration settings or tamper with device firmware.

The underlying weakness: Cleartext Transmission of Sensitive Information

The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

How developers prevent this class of flaw

  • Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
  • When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
  • When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
