CVE-2024-11064
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 · uneditedThe D-Link DSL6740C modem has an OS Command Injection vulnerability, allowing remote attackers with administrator privileges to inject and execute arbitrary system commands through a specific functionality provided by SSH and Telnet.
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 confidenceThe D-Link DSL6740C modem contains an OS Command Injection vulnerability. Remote attackers who already possess administrator credentials can inject and execute arbitrary operating system commands through functionality exposed via the SSH and Telnet services on the device.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the device modelAccess the device admin interface or check the physical device label to confirm the model is D-Link DSL6740CAffected if The device is a D-Link DSL6740C modem - all firmware versions are affected by this vulnerability
-
Check if SSH service is enabledAttempt to connect to the device on port 22 (SSH) or check the device admin interface under network/remote access settings for SSH enable statusAffected if SSH service is enabled and accessible on the device - this provides the injection vector for command execution
-
Check if Telnet service is enabledAttempt to connect to the device on port 23 (Telnet) or check the device admin interface under network/remote access settings for Telnet enable statusAffected if Telnet service is enabled and accessible on the device - this provides an alternate injection vector for command execution
-
Verify administrative access controlsCheck if the device admin interface or services are accessible from untrusted networks, or if default credentials are still in useAffected if Administrative services are exposed to untrusted networks or default credentials remain unchanged - while the attacker needs credentials, weak access controls increase exposure
If you have a D-Link DSL6740C device with SSH or Telnet services enabled and accessible, your device is affected by CVE-2024-11064 regardless of firmware version.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict administrative access to trusted IP addresses only, disable Telnet in favor of SSH with key-based authentication, change default administrator credentials immediately, and apply any available firmware updates from D-Link.
