CVE-2025-3463: CWE-295 Improper Certificate Validation in ASUS DriverHub
"This issue is limited to motherboards and does not affect laptops, desktop computers, or other endpoints." An insufficient validation vulnerability in ASUS DriverHub may allow untrusted sources to affect system behavior via crafted HTTP requests. Refer to the 'Security Update for ASUS DriverHub' section on the ASUS Security Advisory for more information.
AI Analysis
Technical Summary
CVE-2025-3463 is a critical vulnerability classified under CWE-295 (Improper Certificate Validation) affecting ASUS DriverHub software versions prior to 1.0.6.0. DriverHub is a utility designed to assist users in updating and managing drivers on ASUS motherboards. This vulnerability specifically impacts ASUS motherboards and does not affect laptops, desktop computers, or other endpoint devices. The root cause of the issue is insufficient validation of certificates when processing HTTP requests, which could allow an attacker to craft malicious HTTP requests that appear to be from trusted sources. Because the certificate validation is flawed, the software may accept and act upon these malicious requests, potentially leading to unauthorized modification of system behavior. The CVSS 4.0 score of 9.4 (critical) reflects the high severity, with attack vector being network-based (AV:N), no privileges required (PR:N), no user interaction required (UI:P), and high impact on confidentiality, integrity, and availability (VC:H, VI:H, VA:H). The scope is high (S:H), meaning the vulnerability can affect resources beyond the initially vulnerable component. Although no known exploits are currently reported in the wild, the vulnerability's nature and severity make it a significant risk. The vulnerability is limited to ASUS motherboards running the affected DriverHub versions, which are typically used in desktop environments where ASUS motherboards are installed. The improper certificate validation could allow attackers to perform man-in-the-middle (MITM) attacks or inject malicious payloads via crafted HTTP requests, potentially leading to system compromise, unauthorized code execution, or disruption of system operations.
Potential Impact
For European organizations, this vulnerability poses a critical risk particularly to enterprises and institutions that rely on ASUS motherboards with DriverHub installed for driver management. Successful exploitation could lead to unauthorized system control, data breaches, or disruption of critical IT infrastructure. Given the high impact on confidentiality, integrity, and availability, sensitive data could be exposed or altered, and system stability compromised. This is especially concerning for sectors such as finance, healthcare, government, and critical infrastructure, where ASUS motherboards are deployed in servers or workstations. The network-based attack vector and lack of required privileges mean attackers can exploit this vulnerability remotely without authentication, increasing the threat surface. The requirement for only limited user interaction (UI:P) suggests that exploitation could be facilitated by social engineering or automated attack tools. The vulnerability's limitation to motherboards reduces the scope compared to endpoint-wide vulnerabilities but does not diminish the potential impact on affected systems. Organizations with large ASUS motherboard deployments should consider this vulnerability a high priority for patching and mitigation to prevent potential operational disruptions or data compromise.
Mitigation Recommendations
1. Immediate update of ASUS DriverHub to version 1.0.6.0 or later, as provided by ASUS security advisories, to ensure proper certificate validation is enforced. 2. Disable or uninstall DriverHub on systems where it is not essential, especially in critical environments, to reduce attack surface. 3. Implement network-level protections such as strict firewall rules to restrict outbound HTTP traffic from systems running ASUS DriverHub, limiting exposure to untrusted networks. 4. Employ network monitoring and intrusion detection systems (IDS) to detect anomalous HTTP requests or suspicious traffic patterns targeting DriverHub services. 5. Enforce strict TLS inspection and certificate pinning where possible to prevent man-in-the-middle attacks that could exploit the certificate validation flaw. 6. Educate users about phishing and social engineering risks that could facilitate exploitation requiring user interaction. 7. Maintain up-to-date asset inventories to identify all ASUS motherboard systems running DriverHub to prioritize patching and monitoring efforts. 8. Coordinate with ASUS support and subscribe to their security advisories to receive timely updates and patches.
