Detailsinfo

A vulnerability has been found in MCMS up to 6.2.0 and classified as critical. Affected by this vulnerability is an unknown code of the file /cms/category/list of the component SqlInjectionUtil. The manipulation of the argument size with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The front-end interface /cms/category/list of MCMS <=6.2.0 is vulnerable to SQL injection. The size parameter is directly concatenated into the LIMIT clause of SQL through FreeMarker ${size} without being parameterized and bound. The built-in SqlInjectionUtil employs regular expression blacklist filtering, yet keywords like CREATE/TABLE/SET/PREPARE/EXECUTE are not included in the list, allowing for bypassing. Attackers can execute stacked SQL statements without logging in.
