CWE ID Description
CWE-89 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.

An unauthenticated attacker can exploit it by submitting a specially crafted credentials array to the public login endpoint at POST /user/authenticate. This allows the attacker to manipulate database queries, potentially accessing or modifying sensitive data.

Detection Guidance

To detect this SQL injection vulnerability in Pagekit CMS <= 1.0.18, monitor login attempts to /user/authenticate endpoint for unusual input patterns in the credentials array. Check web server logs for POST requests containing SQL syntax like 'OR 1=1 or UNION SELECT. Use tools like SQLmap to test endpoints for injection flaws.

Impact Analysis

If you use Pagekit CMS <= 1.0.18, an attacker could exploit this to steal sensitive data like user credentials or personal information, alter database contents, or gain unauthorized access to your system. This could lead to data breaches, service disruption, or further attacks.
