CVSS v3.1

Official Description

Verizon 5G Home LVSKIHP OutDoorUnit (ODU) 3.33.101.0 does not property sanitize user-controlled parameters within the DMACC URLs on the Settings page of the Engineering portal. An authenticated remote attacker on the local network can inject shell metacharacters into /usr/lib/lua/5.1/luci/controller/admin/settings.lua to achieve remote code execution as root.

Technical Analysis

CVE-2022-28374 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
