Remediation
Vendor solution
ETIC Telecom recommends updating the firmware of the affected devices to the following versions:
* ETIC Telecom RAS: version 4.7.0 or later https://www.etictelecom.com/en/softwares-download/
For the installed devices, ETIC Telecom recommends:
* For all firmware versions 4.7.0 and above, there is a code signature verification for firmware packages. For versions prior to 4.7.0, to reduce the attack surface, we advise the user to verify: (1) That the downloaded firmware comes from a trusted source (ETIC Telecom web site), and (2) The hash of the firmware files.
