CVE-2024-5291
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 · uneditedD-Link DIR-2150 GetDeviceSettings Target Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2150 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SOAP API interface, which listens on TCP port 80 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21235.
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 confidenceD-Link DIR-2150 routers contain a command injection vulnerability in the SOAP API service (TCP port 80). The SOAP interface fails to validate user-supplied input before passing it to system calls, allowing unauthenticated attackers to execute arbitrary code with root privileges.

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 router's web interface or check the device label/metadata to confirm it is a D-Link DIR-2150 router.Affected if The device is not a D-Link DIR-2150 model.
-
Check the firmware versionLog into the router's web interface and navigate to the Status or System Information page to view the installed firmware version. Alternatively, check via CLI if available or examine the firmware file if dumped.Affected if The installed firmware version is exactly 1.06b01.
-
Verify the SOAP API service is accessibleCheck if TCP port 80 is open and listening on the router. Attempt to access the SOAP endpoint (typically /soap or /soap.cgi) via HTTP from the router's LAN or WAN interface depending on configuration.Affected if Port 80 is open and the SOAP API endpoint responds to requests.
-
Confirm web interface exposureDetermine if the router's web management interface (port 80/HTTP) is exposed to untrusted networks. Check router firewall settings and WAN accessibility by attempting to access the router's IP from an external network.Affected if The web interface and SOAP service are reachable from untrusted or external networks.
A user is affected if they are running D-Link DIR-2150 firmware version 1.06b01 with the SOAP API service (port 80) accessible, as this specific version contains the unauthenticated command injection flaw in the SOAP interface.

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 access to the router's web interface from untrusted networks, apply available firmware updates, or disable the SOAP API service if not required.
