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
A missing authorization vulnerability in the web management interface of FatPipe WARP, IPVPN, and MPVPN software prior to versions 10.1.2r60p91 and 10.2.2r42 allows a remote attacker to access at least the URL "/fpui/jsp/index.jsp" leading to unknown impact, presumably some violation of confidentiality. Older versions of FatPipe software may also be vulnerable. The FatPipe advisory identifier for this vulnerability is FPSA004.

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 · moderate confidence

A missing authorization vulnerability in the web management interface of FatPipe WARP, IPVPN, and MPVPN allows unauthenticated remote attackers to access the management URL '/fpui/jsp/index.jsp' without proper authentication, potentially leading to unauthorized access to the device management console and confidentiality violations.

MitigationUpgrade to FatPipe versions 10.1.2r60p91, 10.2.2r42 or later. If immediate patching is not feasible, restrict network access to the management interface using firewall rules or VPN tunnels to prevent unauthorized external access.

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. Confirm FatPipe device type
    Access the device web interface or CLI and identify the model (WARP, IPVPN, or MPVPN). This can typically be done via the login page, device status page, or CLI command like 'show system info'.
    Affected if The device is a FatPipe WARP, IPVPN, or MPVPN model.
  2. Check installed firmware version
    Locate the firmware version in the device web interface (usually under System Status, About, or Maintenance) or via CLI command such as 'show version' or 'get firmware version'. Compare the version number against the affected list: 5.2.0, 6.1.2, 7.1.2, 9.1.2, 10.1.2, or 10.2.2.
    Affected if The installed firmware version matches exactly one of these: 5.2.0, 6.1.2, 7.1.2, 9.1.2, 10.1.2, or 10.2.2.
  3. Test unauthenticated access to management URL
    Attempt to access the endpoint '/fpui/jsp/index.jsp' directly via HTTP/HTTPS without providing any login credentials. For example: http://[device-ip]/fpui/jsp/index.jsp or https://[device-ip]/fpui/jsp/index.jsp.
    Affected if The page loads successfully and displays the management console or login interface without requiring authentication.
  4. Verify management interface exposure
    Check if the web management interface is accessible from untrusted networks (such as directly from the internet or untrusted VLANs) by attempting access from an external IP or non-management network segment.
    Affected if The device management interface (port 80/443 or custom management ports) is reachable from untrusted networks without VPN or firewall restrictions.

If the device is a FatPipe WARP, IPVPN, or MPVPN running firmware version 5.2.0, 6.1.2, 7.1.2, 9.1.2, 10.1.2, or 10.2.2 AND the /fpui/jsp/index.jsp endpoint is accessible without authentication from an untrusted network, the environment is affected by CVE-2021-27858.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to FatPipe versions 10.1.2r60p91, 10.2.2r42 or later. If immediate patching is not feasible, restrict network access to the management interface using firewall rules or VPN tunnels to prevent unauthorized external access.

Recommended fix High confidence

10.1.2r60p91 or 10.2.2r42

  1. Identify the current FatPipe firmware version (WARP, IPVPN, or MPVPN) running on the device
  2. Navigate to FatPipe's official support or download page (www.fatpipeinc.com) to obtain the fixed firmware version
  3. Download firmware version 10.1.2r60p91 or 10.2.2r42 (whichever is compatible with your device model)
  4. Follow FatPipe's standard firmware upgrade procedure documented in the product manual to apply the update
  5. After upgrading, verify the version change was successful and test that the /fpui/jsp/index.jsp URL now requires proper authentication
