This vulnerability exists in the Yi Technology YI Home Camera 2 version 2.1.1_20171024151200, specifically in an unknown function related to the WPA/WPS component. It allows an attacker within the local network to manipulate the device to use a hard-coded cryptographic key. The attack is complex and difficult to exploit, but the exploit has been publicly disclosed.
How can this vulnerability impact me? :
If exploited, this vulnerability could allow an attacker on the local network to bypass normal cryptographic protections by forcing the device to use a hard-coded key. This could potentially weaken the security of the device's wireless communications, making it easier for an attacker to intercept or manipulate data. However, the attack is difficult to perform and requires local network access.
