CVE-2025-4676
Device web HMI authenticates user by validating the first character of the session cookie and authentication token. So, if only the first characters of the session cookie and token are correct, a user will be validated. An attacker can easily brute force the first character of both session cookie and bearer token. This vulnerability allows an attacker to easily bypass the authentication implemented on the device.

Frequently Asked Questions
What causes the vulnerability? - 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 ?Vulnerability severity and details? for further details. What is WebPro SNMP Card PowerValue? - 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. What might an attacker use the vulnerability to do? - 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. How could an attacker exploit the vulnerability? - 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. Could the vulnerability be exploited remotely? - Yes, an attacker who has network access to an affected system node could exploit this vulnerability. Recommended practices include that User?s 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.

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability.
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most recent version available. Also recognize VPN is only as secure as its connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
