Detailsinfo

A vulnerability was found in Craft CMS up to 4.10.2/5.5.4 and classified as critical. This issue affects the function unserialize of the component Commerce TotalRevenue Widget. The manipulation 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:

Craft Commerce is an ecommerce platform for Craft CMS. In versions 4.0.0 through 4.10.2 and 5.0.0 through 5.5.4, there is an SQL injection vulnerability in the Commerce TotalRevenue widget which allows any authenticated control panel user to achieve remote code execution through a four-step exploitation chain. The attack exploits unsanitized widget settings interpolated into SQL expressions, combined with PDO's default multi-statement query support, to inject a maliciously serialized PHP object into the queue table. When the queue consumer processes the injected job, the unrestricted unserialize() call in yii2-queue instantiates a GuzzleHttp FileCookieJar gadget chain whose __destruct() method writes a PHP webshell to the server's webroot. The complete chain requires only three HTTP requests, no administrative privileges, and results in arbitrary command execution as the PHP process user, with queue processing triggered via an unauthenticated endpoint. This issue has been fixed in versions 4.10.3 and 5.5.5.
