CVE-2024-11067
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 a Path Traversal Vulnerability, allowing unauthenticated remote attackers to exploit this vulnerability to read arbitrary system files. Additionally, since the device's default password is a combination of the MAC address, attackers can obtain the MAC address through this vulnerability and attempt to log in to the device using the default password.
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 unauthenticated path traversal vulnerability in its web interface that allows remote attackers to read arbitrary system files. Attackers can exploit this to obtain the device's MAC address, which is used to derive the default password, enabling full device compromise.

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 D-Link DSL6740C device on your networkCheck your network inventory or physically inspect devices for the DSL6740C model label. You can also scan your network for the device by checking for D-Link HTTP service responses or MAC address OUI prefix 00:1E:58 (D-Link common prefix).Affected if The device with model DSL6740C exists on your network.
-
Confirm web interface accessibilityAttempt to access the device's web interface by navigating to its LAN or WAN IP address via HTTP/HTTPS (typically http://192.168.1.1 for LAN). Use curl or a browser to check if the login page responds.Affected if The web interface is reachable from any network segment you control.
-
Verify device is not isolated behind restricted accessReview your firewall or access control rules to determine if the device's HTTP port (80/443) is exposed to untrusted networks or if management access is limited to a specific admin VLAN only.Affected if The web management interface is accessible from non-admin network segments or the WAN interface.
You are affected if you have a D-Link DSL6740C device on your network and its web interface is accessible, since all firmware versions contain the path traversal vulnerability.

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 network access to the device's management interface, change the default password to a strong unique value, and contact D-Link for firmware updates; if no update is available, consider replacing the device.
