Technical details
The SNMPv3 authentication and encryption keys are hardcoded constants set during build compilation and seeded in the open-source community build, with the same values deployed on every device. These keys are not rotated when administrator passwords are reset, meaning they persist through normal account provisioning. An attacker with knowledge of the keys (recoverable from public source code) can authenticate to SNMPv3 and decrypt all SNMP traffic, gaining full administrative privileges over affected systems.
