CVE-2025-62776 is a vulnerability identified in the installer of WTW EAGLE (for Windows) version 3.0.8.0, a product by Wireless Tsukamoto Co., Ltd. The core issue is an uncontrolled search path element for Dynamic Link Libraries (DLLs) during the installation process. Specifically, the installer does not securely specify the DLL search path, allowing an attacker to place a malicious DLL in a location that the installer will load before the legitimate DLL. This DLL hijacking can lead to arbitrary code execution with the privileges of the installer, which typically runs with elevated rights. The CVSS v3.0 score of 7.8 reflects a high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact on confidentiality, integrity, and availability is high since arbitrary code execution can compromise the system fully. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk if exploited. The vulnerability is particularly concerning for environments where WTW EAGLE is used for critical operations, as it could be leveraged to gain persistent footholds or escalate privileges. The vulnerability was published on October 29, 2025, with no patch links currently available, indicating that organizations should monitor for vendor updates and apply mitigations proactively.

For European organizations, the impact of CVE-2025-62776 can be substantial, especially in sectors relying on WTW EAGLE software for scientific, industrial, or technical applications. Successful exploitation could allow attackers to execute arbitrary code with elevated privileges during installation, potentially leading to full system compromise. This could result in data breaches, disruption of critical operations, and unauthorized access to sensitive information. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, as attackers could leverage social engineering or insider threats. Organizations with less mature endpoint security or those that allow users to install software without strict controls are particularly vulnerable. The high impact on confidentiality, integrity, and availability means that exploitation could lead to significant operational and reputational damage. Additionally, the lack of a current patch increases the window of exposure, necessitating immediate mitigation efforts.

1. Monitor Wireless Tsukamoto Co., Ltd. communications and apply official patches for WTW EAGLE as soon as they are released. 2. Restrict the DLL search path by configuring the system environment and installer execution context to avoid loading DLLs from untrusted directories. 3. Employ application whitelisting to ensure only authorized installers and DLLs can execute. 4. Use endpoint detection and response (EDR) tools to monitor for anomalous DLL loading behaviors during installation processes. 5. Educate users about the risks of running installers from untrusted sources or locations, emphasizing the need to avoid executing installers in directories writable by untrusted users. 6. Implement least privilege principles to limit user rights, reducing the impact of any arbitrary code execution. 7. Conduct regular audits of software installation practices and environment configurations to detect and remediate insecure DLL search paths. 8. Consider isolating installation environments or using virtual machines for software installation to contain potential exploitation.
