CVE-2025-3462 is a high-severity vulnerability affecting ASUS DriverHub software versions prior to 1.0.6.0, specifically on ASUS motherboards. The vulnerability is classified under CWE-346, which refers to an origin validation error. This means that the software insufficiently validates the origin of HTTP requests it processes, allowing unauthorized or malicious sources to interact with DriverHub's features. DriverHub is a utility designed to manage and update drivers on ASUS motherboards, and improper origin validation can lead to unauthorized commands or actions being executed via crafted HTTP requests. The vulnerability does not affect laptops, desktop computers, or other endpoints, limiting its scope strictly to motherboards running the vulnerable DriverHub versions. The CVSS 4.0 base score is 8.4, indicating a high severity level. The vector details show that the attack vector is network-based (AV:N), requires no privileges (PR:N), and no user authentication (AT:N), but does require user interaction (UI:P). The impact on confidentiality and integrity is low, but availability impact is high, suggesting that exploitation could disrupt system functionality or cause denial of service. No known exploits are currently in the wild, and ASUS has published a security advisory recommending updates to version 1.0.6.0 or later to remediate the issue. The vulnerability's exploitation could allow attackers to perform unauthorized actions on affected motherboards remotely, potentially disrupting system stability or enabling further attacks on the system firmware or hardware management features.

For European organizations, this vulnerability poses a significant risk primarily to environments using ASUS motherboards with DriverHub software versions before 1.0.6.0. The potential impact includes unauthorized remote interactions with motherboard management features, which could lead to system instability, denial of service, or disruption of critical infrastructure relying on these systems. Given that the vulnerability does not affect laptops or desktop computers broadly, the impact is more focused on servers, workstations, or specialized hardware using ASUS motherboards. In sectors such as manufacturing, telecommunications, or government infrastructure where ASUS motherboards are deployed, exploitation could disrupt operations or lead to downtime. The requirement for user interaction reduces the likelihood of automated widespread exploitation but does not eliminate targeted attacks, especially in environments where users might be tricked into interacting with malicious content. The lack of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation. Organizations with critical infrastructure or sensitive operations should prioritize patching to prevent potential compromise or service disruption.

European organizations should take the following specific actions: 1) Identify all ASUS motherboards in their infrastructure running DriverHub versions prior to 1.0.6.0. This may require inventory audits and endpoint management tools. 2) Immediately update DriverHub to version 1.0.6.0 or later as provided by ASUS security advisories. 3) Restrict network access to management interfaces of affected motherboards to trusted internal networks only, reducing exposure to external attackers. 4) Implement network-level HTTP request filtering or web application firewall (WAF) rules to detect and block suspicious or unauthorized HTTP requests targeting DriverHub features. 5) Educate users about the risks of interacting with unsolicited or suspicious content that could trigger the required user interaction for exploitation. 6) Monitor network and system logs for unusual HTTP requests or interactions with DriverHub components. 7) Coordinate with ASUS support for any additional security patches or mitigations specific to their hardware models. These steps go beyond generic patching by emphasizing network segmentation, user awareness, and proactive monitoring tailored to the nature of the vulnerability.
