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
Multiple stack-based buffer overflows in Free Download Manager (FDM) before 3.0.852 allow remote attackers to execute arbitrary code via vectors involving (1) the folders feature in Site Explorer, (2) the websites feature in Site Explorer, (3) an FTP URI, or (4) a redirect.

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

Free Download Manager (FDM) versions prior to 3.0.852 contain multiple stack-based buffer overflow vulnerabilities in the Site Explorer component (folders and websites features) and in FTP URI handling/redirect processing. These flaws allow remote attackers to execute arbitrary code by sending specially crafted responses via FTP connections or malicious redirects.

MitigationUpgrade to Free Download Manager version 3.0.852 or later. Since the CVSS score is 10 (Critical) with remote code execution capability, prioritize patching all systems with FDM installed immediately.

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. Verify Free Download Manager installation
    Check for FDM installation by looking for 'Free Download Manager' in installed programs on Windows, or checking common installation paths such as C:\Program Files\Free Download Manager or C:\Program Files (x86)\Free Download Manager. On Linux, check /usr/local/fdm or user's home directory for fdm binaries.
    Affected if Free Download Manager is installed on the system
  2. Determine installed FDM version
    Open Free Download Manager and navigate to Help > About, or right-click the executable and select Properties > Details to view the version number. Compare this version against the affected list: versions 2, 2.1, 2.5.700, 2.5.704, 2.5.724, 3.0.843, 3.0.848, 3.0.850, or any version prior to 3.0.852.
    Affected if Installed version is 3.0.851 or lower, or matches any of the specific affected versions listed (2, 2.1, 2.5.700, 2.5.704, 2.5.724, 3.0.843, 3.0.848, 3.0.850)
  3. Check Site Explorer component usage
    Launch FDM and look for the Site Explorer panel, typically found in the main window under a tab or sidebar labeled 'Site Explorer' or 'Sites'. This component handles folder and website management features.
    Affected if Site Explorer feature is accessible or has been used to manage folders or websites
  4. Verify FTP download functionality usage
    Check if any FTP downloads have been added or are active in FDM. Look for ftp:// URIs in the download queue or check download history for entries using FTP protocol.
    Affected if FTP downloads have been performed or FTP URIs are present in the download list

The system is affected if Free Download Manager version 3.0.851 or lower (or any of the specific versions 2, 2.1, 2.5.700, 2.5.704, 2.5.724, 3.0.843, 3.0.848, 3.0.850) is installed AND the Site Explorer or FTP download features have been used.
