Vodafone has denied a report saying issues found in equipment supplied to it by Huawei in Italy in 2011 and 2012 could have allowed unauthorized access to its fixed-line network there.
The issue is not new, as other nations claimed that China-based telco is a spy of Beijing.
Also, citing Bloomberg report have said that Vodafone found security flaws in software that could have given Huawei unauthorised access to Italian homes and businesses.
The US refuses to utilized Huawei equipment for security reasons.
However, reports suggest the UK may let the firm help build its 5G network.
This is despite the US wanting the UK and its other allies in the “Five Eyes” intelligence grouping – Canada, Australia and New Zealand – to exclude the company.
Australia and New Zealand have already blocked telecoms companies from using Huawei equipment in 5G networks, while Canada is reviewing its relationship with the Chinese telecoms firm.
“The issues in Italy identified in the Bloomberg story were all resolved and date back to 2011 and 2012,” Vodafone said in a statement.
“The ‘backdoor’ that Bloomberg refers to is Telnet, which is a protocol that is commonly used by many vendors in the industry for performing diagnostic functions. It would not have been accessible from the internet.
