CVE-2025-62776 is a vulnerability identified in the installer of Wireless Tsukamoto Co., Ltd.'s WTW EAGLE software for Windows, specifically version 3.0.8.0. The issue stems from an uncontrolled search path element in the Dynamic Link Library (DLL) loading process. When the installer runs, it searches for required DLLs in directories that may be insecure or user-controllable, allowing an attacker to place a malicious DLL in one of these locations. Upon execution, the installer inadvertently loads the malicious DLL instead of the legitimate one, resulting in arbitrary code execution with the privileges of the installer process. The vulnerability requires local access and user interaction (such as running the installer), but no prior authentication is needed. The CVSS v3.0 score of 7.8 reflects high confidentiality, integrity, and availability impacts, with low attack complexity but limited to local vectors. Although no public exploits have been reported, the flaw represents a significant risk, especially in environments where WTW EAGLE is deployed for critical operations. The lack of a patch link indicates that a fix may not yet be publicly available, underscoring the need for mitigation strategies until an official update is released.

For European organizations, this vulnerability could lead to severe consequences including unauthorized system access, data breaches, and disruption of services if exploited. Since the installer runs with elevated privileges, successful exploitation could allow attackers to gain control over affected systems, potentially leading to lateral movement within networks and compromise of sensitive information. Industries relying on WTW EAGLE for operational or analytical tasks—such as manufacturing, engineering, or research—may face operational downtime and reputational damage. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, especially in environments with shared or poorly controlled endpoints. Additionally, the high confidentiality and integrity impact could affect compliance with European data protection regulations like GDPR, exposing organizations to legal and financial penalties.

European organizations should immediately review the deployment of WTW EAGLE version 3.0.8.0 and restrict installer execution to trusted administrators only. Until an official patch is released, implement application whitelisting and restrict write permissions on directories involved in DLL loading to prevent unauthorized DLL placement. Employ endpoint detection and response (EDR) solutions to monitor for suspicious DLL loading behaviors and anomalous installer activity. Conduct user awareness training to prevent inadvertent execution of untrusted installers. Additionally, consider isolating systems running WTW EAGLE installers from critical network segments to limit potential lateral movement. Regularly audit installed software versions and maintain an inventory to quickly identify vulnerable instances. Engage with Wireless Tsukamoto Co., Ltd. for updates or patches and apply them promptly once available.
