Detailsinfo

A vulnerability, which was classified as problematic, has been found in YzmCMS 7.5. This issue affects the function get_arrchildid of the file application/admin/controller/category.class.php of the component Category. The manipulation of the argument parentid with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A SQL injection vulnerability was found in YzmCMS 7.5. The issue occurs in the get_arrchildid() function within application/admin/controller/category.class.php, where the user-controlled parentid parameter is concatenated directly into a FIND_IN_SET() SQL clause without proper sanitization. This allows an authenticated administrator to execute arbitrary SQL queries via boolean-based blind injection, potentially leading to full database compromise.
