Description

The Aclara Metrum Cellular Web Interface is vulnerable to unauthorized access due to the absence of authentication controls on critical system functions. This weakness exposes essential configuration settings, allowing attackers to alter operational parameters and trigger system restarts without restriction. Such unauthorized changes can disrupt normal functionality and, if performed repeatedly, may lead to a loss of communications to the device.
