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
An OS command injection vulnerability was discovered in D-Link DSL-3782 v1.01 via the inIP, insPort, inePort, exsPort, exePort, and protocol parameters. This vulnerability allows attackers to execute arbitrary operating system (OS) commands via a crafted packet.

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

D-Link DSL-3782 router firmware version 1.01 contains an OS command injection vulnerability in the web management interface. Attackers can inject arbitrary OS commands through the inIP, insPort, inePort, exsPort, exePort, and protocol parameters via crafted HTTP requests, potentially achieving full device compromise.

MitigationReplace the end-of-life D-Link DSL-3782 with a currently supported router; if immediate replacement is not possible, disable remote web management and restrict local access to trusted IPs only.

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. Identify device model
    Access the router web management interface (typically http://192.168.1.1) and navigate to the Status or Device Info page to confirm the device is D-Link DSL-3782.
    Affected if Device model is D-Link DSL-3782
  2. Check firmware version
    In the web UI status page, locate the firmware version field. Alternatively, check the footer or system settings for the exact version number.
    Affected if Firmware version is 1.01 exactly (no other versions are listed as affected)
  3. Verify web management interface is enabled
    Attempt to access the router web UI via HTTP or HTTPS. Check in Settings > Management or Administration > Remote Management to see if the web interface is enabled.
    Affected if Web management interface is accessible (either locally or remotely)
  4. Check remote management settings
    Navigate to the router's Administration or Management settings and look for options like 'Remote Management', 'Web Management', or 'HTTP/HTTPS Access' to determine if the interface is reachable from the WAN (internet) side.
    Affected if Remote web management is enabled, exposing the interface to untrusted networks

You are affected if you have a D-Link DSL-3782 router running firmware version 1.01 with the web management interface enabled and accessible.
