Vulnerability Details
The vulnerability is officially described as a CWE-798 vulnerability, which refers to the use of hard-coded credentials. The CVSS score of 9.8 indicates a critical severity, highlighting the need for immediate action. This vulnerability affects Schneider Electric’s Easergy firmware across various models, published on February 9, 2022.
The CVSS 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating that it is exploitable over the network with low complexity and requires no privileges or user interaction. The impacts on confidentiality, integrity, and availability are all rated as high.
Technical Analysis
The root cause of this vulnerability stems from hard-coded credentials within the firmware of affected Schneider Electric devices. The attack vector is network-based, allowing potential attackers to exploit this vulnerability remotely. The attack complexity is low, making it easier for attackers to exploit this vulnerability once they have the necessary credentials.
Importantly, no privileges are required for exploitation, and there is no need for user interaction. This increases the risk level, as unauthorized attackers could exploit the vulnerability without needing any inside knowledge.
The potential impacts on confidentiality, integrity, and availability are all rated as high, meaning successful exploitation could lead to critical data breaches and severe operational disruptions.
Risk & Impact Analysis
