Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.",

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 de-tails 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.",

        "category": "faq",
        "text": "What causes the vulnerability?\n\n- The vulnerabilities are caused by code defects allowing the attacker to do various unintended, unauthorized actions on the target device. Please look at the description of the respective vulnerabilities in section \u201cVulnerability severity and details\u201d for further details.\n\nWhat is WebPro SNMP Card PowerValue?\n\n- The WebPro SNMP Card PowerValue provide web server to monitor and manage multiple UPS products in networked environment. It can detect temperature and humidity for the environment via connecting to EMD (Environmental Monitoring Device). It can not only prevent data loss from power outage and safely shutdown systems but also store programming data and scheduled shut down the UPS. All UPS warning and fault event records can be kept in WebPro SNMP Card PowerValue.\n\nWhat might an attacker use the vulnerability to do?\n\n- If mentioned vulnerabilities have been successfully exploited by an attacker, this could allow the attacker to take control of the target WebPro SNMP Card PowerValue device.\n\nHow could an attacker exploit the vulnerability?\n\n- An attacker could try to exploit the vulnerability by creating a specially crafted message and sending the message to WebPro SNMP Card PowerValue device. This would require that the attacker has access to the system network, by connecting to the network either directly or through a wrongly configured or penetrated security system.\n\nCould the vulnerability be exploited remotely?\n\n- Yes, an attacker who has network access to an affected system node could exploit this vulnerability. Recommended practices include that User\u2019s network systems are physically protected, have no direct connections to the Internet nor any other untrusted network, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed.\n\nWhat does the update do?\n\n- WebPro SNMP Card PowerValue v1.1.8.p update has fixes for all the vulnerabilities mentioned in \u201cVulnerability severity and details\u201d section.\n\nWhen this security advisory was issued, had this vulnerability been publicly disclosed?\n\n- No, the vulnerabilities have not been publicly disclosed.\n\nWhen this security advisory was issued, had ABB received any reports that this vulnerability was being exploited?\n\n- No, ABB had not received any information indicating that this vulnerability had been exploited when this security advisory was originally issued.",
