Sorry, slight problem there, which goes to the very heart of the issue. Huawei engineers are on the network all the time, using the OSS for software upgrades, technology and site additions etc.
Vulnerabilities like this are vulnerabilities. Period. Huawei A) knows the full topology of the network B) by leaving these protocols running they can easily go from places they have access and control over to places they shouldn’t. I think the original criticism, while technically not consistent with the narrative, is more than valid.
