Official description

Incorrect Use of Privileged APIs vulnerability in Yepas Digital Yepas allows Collect Data as Provided by Users. This issue affects Digital Yepas: before 1.0.1.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Incorrect Use of Privileged APIs

The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.

How developers prevent this class of flaw

  • Before calling privileged APIs, always ensure that the assumptions made by the privileged code hold true prior to making the call.
  • Know architecture and implementation weaknesses of the privileged APIs and make sure to account for these weaknesses before calling the privileged APIs to ensure that they can be called safely.
  • If privileged APIs make certain assumptions about data, context or state validity that are passed by the caller, the calling code must ensure that these assumptions have been validated prior to making the call.
