Readers are reminded that the certification of this product (TOE) is the result of maintenance, rather than an actual re-evaluation of the product.  Maintenance only considers the affect of TOE changes on the assurance baseline (i.e. the original evaluated TOE); maintenance is not intended to provide assurance in regard to the resistance of the TOE to new vulnerabilities or attack methods discovered since the date of the initial certificate.  Such assurance can only be gained through re-evaluation. 

Using a security impact analysis of the changes made to the TOE, which was provided by the developer, the CCEVS has determined that the impact of changes on the TOE are considered minor and that independent evaluator analysis was not necessary.  A summary of the results can be found in the Maintenance Report, which is written in relation to the product's original validation report and Security Target.  Readers are therefore reminded to read the Security Target, Validation Report, and the Assurance Maintenance Report to fully understand the meaning of what a maintained certificate represents. 

Product Description

Each of the changes to “Crestron DigitalMedia NVX®AV-over-IP v5.2” fell into the following categorization:

Major Changes


Minor Changes


The TOE was revised with the following changes but remains Crestron DigitalMedia NVX®AV-over-IP v5.2.

1        Hardware changes – The DM-NVX-360 and DM-NVX-360C models were added to the list of appliance models. They are essentially identical to the previously evaluated CM-NVX-363 and DN-NVX-363C models with the exception that certain audio processing hardware was removed. The NVX models all use the same firmware image files and provide equivalent security-relevant functionality. There are no security relevant differences between any of the appliance models.

2        The product firmware version was updated from: 5.2.4651.00030 to 5.2.4651.00032.

Product Firmware Changes


SafeLogic OpenSSL was updated from version 1.0.2x to version 1.0.2zd


The underlying FIPS module was unchanged and so CAVP certification was unaffected

Software vulnerabilities were resolved.


·         CVE-2021-23840 which affects all encryption/decryption;

·         CVE-2021-23841, CVE-2021-3712, CVE-2022-0778 which all are related to reading certificate information; and

·         CVE-2021-4160, CVE-2021-23839 are related to features not related to the TOE.

Link Layer Discovery Protocol (LLDP) Power over Ethernet (PoE) negotiation was modified to prevent startup problems with certain non-conforming switches.


This Layer 2 Ethernet functionality is used for basic hardware negotiation and so has no security relevant functionality.


Coredump information was minimized to avoid SDCARD overuse.


This change has no security relevant functionality
