phpMyFAQ is an open source FAQ web application for PHP 8.1+ and MySQL, PostgreSQL and other databases. phpMyFAQs user removal page allows an attacker to spoof another users detail, and in turn make a compelling phishing case for removing another users account. The front-end of this page doesnt allow changing the form details, an attacker can utilize a proxy to intercept this request and submit other data. Upon submitting this form, an email is sent to the administrator informing them that this user wants to delete their account. An administrator has no way of telling the difference between the actual user wishing to delete their account or the attacker issuing this for an account they do not control. This issue has been patched in version 3.2.5.

Weakness

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.
