There is no fixed version for intelliants/subrion.
Overview
intelliants/subrion is a open source php content management system.
Affected versions of this package are vulnerable to Deserialization of Untrusted Data
in admin/blocks.php which allows PHP Object Injection (with resultant file deletion) via serialized data in the subpages value within a block to blocks/edit.
Details
Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database).
Deserialization of untrusted data (CWE-502), is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, letting the attacker to control the state or the flow of the execution.
An attacker just needs to identify a piece of software that has both a vulnerable class on its path, and performs deserialization on untrusted data. Then all they need to do is send the payload into the deserializer, getting the command executed.
