| Packagist | shopware/shopware | >= 5.3.0, <= 5.6.0 | no fix listed |
Details
As written in the advisory (Markdown source, shown as plain text).
In createInstanceFromNamedArguments in Shopware through 5.6.x, a crafted web request can trigger a PHP object instantiation vulnerability, which can result in an arbitrary deserialization if the right class is instantiated. An attacker can leverage this deserialization to achieve remote code execution. NOTE: this issue is a bypass for a CVE-2017-18357 whitelist patch.
