> DESCRIPTION

phpMyFAQ is an open source FAQ web application. Prior to version 4.2.0-alpha, an authenticated SQL LIKE wildcard injection vulnerability in phpMyFAQ’s chat user search allows any logged-in user to bypass the intended display-name search filter and enumerate active users. The endpoint escapes SQL string syntax but does not escape `%` and `_`, which remain active `LIKE` wildcards. Version 4.2.0-alpha patches the issue.

CWE-20 CWE-89 CWE-200

> CWE DETAILED DESCRIPTIONS

CWE-20: Improper Input Validation - The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. | CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') - The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. | CWE-200: Exposure of Sensitive Information to an Unauthorized Actor - The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
