The wpDataTables – Tables & Table Charts premium WordPress plugin before 3.4.2 has Improper Access Control. A low privilege authenticated user that visits the page where the table is published can tamper the parameters to access the data of another user that are present in the same table by taking over the user permissions on the table through formdata[wdt_ID] parameter. By exploiting this issue an attacker is able to access and manage the data of all users in the same table.

Weakness

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
