Official description

D-Link D-View queryDeviceCustomMonitorResult Exposed Dangerous Method Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of D-Link D-View. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the queryDeviceCustomMonitorResult method. The issue results from an exposed dangerous method. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21842.

The underlying weakness: Exposed Dangerous Method or Function

The product provides an Applications Programming Interface (API) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted.

How developers prevent this class of flaw

  • If you must expose a method, make sure to perform input validation on all arguments, limit access to authorized parties, and protect against all possible vulnerabilities.
  • Identify all exposed functionality. Explicitly list all functionality that must be exposed to some user or set of users. Identify which functionality may be: accessible to all users restricted to a small set of privileged users prevented from being directly accessible at all Ensure that the implemented code follows these expectations. This includes setting the appropriate access modifiers where applicable (public, private, protected, etc.) or not marking ActiveX controls safe-for-scripting.
