Also, understand that VPNs are only as secure as the connected devices.\n",

Occasionally an issue is determined to be a design or coding flaw with implications that may impact product cyber security.\n\nWhen a potential product vulnerability is identified or reported, ABB immediately initiates our vulnerability handling process. This entails validating if the issue is in fact a product issue, identifying root causes, determining what related products may be impacted, developing a remediation, and notifying end users and governmental organizations.\n\nThe resulting Cyber Security Advisory intends to notify customers of the vulnerability and provide details on which products are impacted, how to mitigate the vulnerability or explain workarounds that minimize the potential risk as much as possible. The release of a Cyber Security Advisory should not be misconstrued as an affirmation or indication of an active threat or ongoing campaign targeting the products mentioned here. If ABB is aware of any specific threats, it will be clearly mentioned in the communication.\n\nThe publication of this Cyber Security Advisory is an example of ABB\u2019s commitment to the user community in support of this critical topic. Responsible disclosure is an important element in the chain of trust we work to maintain with our many customers. The release of an Advisory provides timely information which is essential to help ensure our customers are fully informed.",

        "text": "What causes the vulnerability?\n\nThe vulnerability is caused by code defect allowing the attacker to extract the sensitive information such as user credentials from memory dump of the application. Please refer to Vulnerability severity and details for further details.\n\nWhat is MConfig ?\n\nMConfig is the parameterizing software for ABB LV switchgear components such as motor and feeder controller, operation panel, temperature monitoring solutions and protocol converter. The components are physically installed in a low voltage switchgear located in switch rooms that require authority to access.\nTo run this software on a host machine (computer), the operating system should be Win11 or later version.\n\nWhat might an attacker use the vulnerability to do?\n\nIf the mentioned vulnerability has been successfully exploited by an attacker, this could allow the attacker to extract sensitive information such as user credentials.\n\nWith user credentials and access to a host machine with MConfig installed, and access to the switch room with components installed in a switchgear, the attacker can modify the setting of the components potentially compromising its correct operation.\n\nHow could an attacker exploit vulnerability?\n\nAn attacker with host machine physical access could, after a user log into MConfig, exploit a vulnerability by exporting a memory dump during runtime, potentially exposing the user\u0027s password.\n\nCould vulnerability be exploited remotely? \n\nThe vulnerability can only be exploited if an attacker has physical access to the host machine with MConfig software.\n\nWhat does the update do?\n\nMConfig version V1.4.9.22 update has fix for the vulnerability mentioned in Vulnerability severity and details section.\n\nThe measures below were implemented to fix the vulnerability:\n\n\u2022 Clear any authentication-related memory data after a successful login.\n\n\u2022 Hash the passwords in SHA256",
