Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
RemoteCall Remote Support Program (for Operator) versions prior to 5.3.0 contain an uncontrolled search path element vulnerability. If a crafted DLL is placed in the same folder with the affected product, it may cause an arbitrary code execution.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

RemoteCall Operator versions before 5.3.0 are vulnerable to DLL hijacking due to an uncontrolled search path element. The application loads DLLs from its working directory without using fully qualified paths, allowing an attacker to place a malicious DLL with the same name in the application directory to achieve arbitrary code execution with the privileges of the running user.

MitigationUpgrade to RemoteCall Operator version 5.3.0 or later, which should contain a fixed search path implementation. Until upgraded, ensure no untrusted files are placed in the application directory.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate RemoteCall Operator installation directory
    Search for 'RemoteCall' or 'RCAgent' folder in Program Files, Program Files (x86), or check the application vendor's default install path. Check Add/Remove Programs or registry for installation location.
    Affected if The application is not found in standard installation directories, suggesting it may not be installed or was installed to a non-standard location.
  2. Identify installed version of RemoteCall Operator
    Right-click the main executable (typically RCAgent.exe or RemoteCall.exe) in the installation folder, select Properties, and view the Details tab for version information. Alternatively, check version info in Add/Remove Programs.
    Affected if No version information is displayed or the executable is not found, preventing version comparison.
  3. Compare installed version against vulnerable range
    If version is found, compare it to 5.3.0. Versions before 5.3.0 (such as 5.2.x, 5.1.x, 5.0.x, etc.) are affected by this DLL hijacking vulnerability.
    Affected if The installed version is below 5.3.0, indicating the application uses the vulnerable DLL search path implementation.
  4. Verify DLL loading behavior exists
    This vulnerability is inherent to versions before 5.3.0 - the application will attempt to load DLLs from its working directory without fully qualified paths. No special configuration check is needed if the version is vulnerable.
    Affected if The application runs with a vulnerable version and processes DLLs, meaning the uncontrolled search path element is present and exploitable.

A user is affected if RemoteCall Operator version 5.3.0 or later is NOT installed, as older versions contain the uncontrolled DLL search path that allows DLL hijacking from the application directory.
