| Exploitation Conditions | Exploitation requires that a malicious DLL bearing a name the WTW EAGLE 3.0.8.0 installer attempts to load already be present in a directory on the installer's DLL search path - in practice the directory from which the installer is executed, such as the victim's Downloads folder. The victim must then actively launch that installer (UI:A), so this is not remotely or automatically triggerable. Limiting factors: local access to place the DLL (or a social-engineering step to co-deliver installer and DLL), mandatory user execution of the installer, and the fact that code runs only with the privileges of the running installer process rather than guaranteed SYSTEM. |
| Impact | This is a classic DLL search-path hijacking flaw (CWE-427) in the WTW EAGLE Windows installer. The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:N/UI:A) and the 8.4 score are driven by the HIGH triple impact (VC:H/VI:H/VA:H - arbitrary code execution), but the real-world risk is substantially tempered by the LOCAL attack vector and the required active user interaction (UI:A): an attacker cannot trigger this remotely and must get a victim to execute the installer while a malicious DLL already sits in the search path. EPSS corroborates low practical urgency at 0.16% (5th percentile), and there is no CISA KEV listing and no public exploit identified at time of analysis, so this is not evidence of active or widespread exploitation. In short, this is a legitimately high-impact-if-triggered issue but a LOW-likelihood one - a high-CVSS, low-real-risk profile typical of installer/DLL-preloading bugs, best treated as a patch-on-cycle item rather than an emergency. One data caveat: the input Tags include 'Microsoft', which appears to be a mislabel - WTW EAGLE is a third-party product (WTW, surveillance/camera management software) that merely runs on Windows, not a Microsoft product; verify vendor attribution before routing. |
| Exploit ScenarioDerived | An attacker plants a malicious DLL with an expected name in a directory that the WTW EAGLE installer searches (commonly the same folder the installer is launched from, such as a browser Downloads directory). When the victim runs the installer, it insecurely loads the attacker's DLL instead of the legitimate one, executing arbitrary code with the privileges of the installer process. No public exploit identified at time of analysis, and exploitation hinges on the victim actively running the trojanized installer. |

Alert meAnalysisAIv1 – Oct 08, 2026
Arbitrary code execution in the WTW EAGLE 3.0.8.0 (Windows) installer stems from an uncontrolled DLL search path (CWE-427) that lets the installer load a library from a location an attacker may control. An unauthenticated attacker able to place a malicious DLL with a name the installer expects into its search path - in practice the folder the installer is launched from, such as the victim's Downloads directory - gains code execution with the privileges of the running installer once the victim starts it, so exploitation hinges on local file placement plus mandatory user interaction (UI:A/UI:R) rather than remote or automatic triggering. Reported to JVN by JPCERT/CC, the issue is not listed in CISA KEV, no public exploit code has been identified at time of analysis, and EPSS is low at 0.16% (5th percentile), which is consistent with a targeted rather than mass-exploited flaw. Note that the vendor's own CVSS 4.0 score of 8.4 and our independent CVSS 3.1 assessment (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) both treat this as unauthenticated but requiring a local placement step and deliberate user execution, with impact confined to the installer process rather than guaranteeing SYSTEM.
RemediationAI
No vendor-released patch with a specific fixed version is identified in the available data, so the primary action is to obtain the vendor's current installer directly from the authoritative advisory channel - review JVN23394606 (https://jvn.jp/en/jp/JVN23394606/) and the WTW support page (https://wtw.support/wtw/eagle-app-cms-win/) and deploy any superseding installer build only from that trusted source, verifying its digital signature before execution. Until a fixed build is confirmed, apply compensating controls that defeat the search-path abuse: never run the 3.0.8.0 installer from a user-writable location such as Downloads or Desktop - stage it in a directory writable only by administrators (for example C:\ProgramData or a protected network share) and execute it from there, and delete or relocate any unexpected DLLs sitting in the same folder as the installer, since the DLL must be co-located to be hijacked; note the trade-off that this relies on operator discipline and does not fix the underlying loader. Where feasible, run the installer under a low-privilege account rather than an administrative one to limit the impact of any hijacked library (accepting that installation may then fail or require elevation for specific components), enable Windows safe DLL search mode / SafeDllSearchMode and audit the environment for writable directories on the load path, and use application control or DLL-blocking policy to prevent unsigned libraries from loading into the installer, with the caveat that aggressive blocking can break legitimate installer dependencies. Finally, treat the installer as untrusted input during distribution: deliver it through software-management or endpoint tooling, and monitor for the pairing of the EAGLE installer with a same-named DLL in the same directory, which is the practical exploitation signature.
Affected ProductsAI
The affected product is WTW EAGLE for Windows, specifically installer version 3.0.8.0, corresponding to CPE entries scoped to WTW EAGLE 3.0.8.0 on the Microsoft Windows platform. Other versions and non-Windows deployments are not identified as affected in the available data, but because the defect lives in the installer's library-loading logic rather than the runtime application, any deployment that uses this specific 3.0.8.0 Windows installer build should be considered at risk. Authoritative product and version detail is published in the JVN advisory JVN23394606 (https://jvn.jp/en/jp/JVN23394606/) with vendor-facing information at https://wtw.support/wtw/eagle-app-cms-win/, which should be consulted to confirm whether newer installer builds supersede 3.0.8.0.

Technical ContextAI · show details
The root cause is CWE-427 (Uncontrolled Search Path Element): the WTW EAGLE Windows installer resolves at least one DLL by name without an absolute or otherwise hardened path, so Windows' DLL search order can be influenced by surrounding directories. In the typical Windows load order the application directory and the current working directory are consulted before system paths depending on safe-DLL-search settings, which means a DLL dropped next to the executable or in the directory from which the installer is invoked can shadow the legitimate library. Because the installer loads this code with its own token, any planted library executes with those privileges; this is the classic DLL search-order hijacking / installer-side-loading pattern. The affected component is specifically the installer for WTW EAGLE for Windows 3.0.8.0, and the CPE scope is limited to that product and version rather than the wider WTW EAGLE application suite. The 'RCE' and 'Microsoft' tags reflect that this yields native Windows code execution through the platform's library-loading mechanism, and the JVN/JPCERT reporting indicates a coordinated disclosure with vendor involvement.

DescriptionCVE.org
The installer of WTW EAGLE (for Windows) 3.0.8.0 contains an issue with the DLL search path, which may lead to insecurely loading Dynamic Link Libraries. As a result, arbitrary code may be executed with the privileges of the running application.
Executive ViewAI
The WTW EAGLE 3.0.8.0 Windows installer contains a high-severity DLL search path vulnerability (CVE-2025-62776) that could allow an attacker to execute arbitrary code with installer privileges if they can place a malicious DLL in the directory from which a user launches the installer. Although exploitation requires local file placement and user interaction, and no public exploit is currently identified, the lack of a vendor patch elevates the risk for organizations that deploy this financial software. Security leadership should direct users to run the installer only from trusted locations and implement interim controls to prevent DLL hijacking until a fix is available.
Run the installer only from a trusted, access-controlled location; enforce application control policies that block DLL loading from non-system or user-writable directories; execute the installer with least privilege; and monitor for suspicious DLL placement in installer folders.
