**Description**
This issue involves the deserialization of untrusted data, which occurs when an application deserializes data without sufficient verification, allowing an attacker to control the execution flow or state. In this case, the software allows the deserialization of arbitrary .NET classes, which can be abused to achieve remote code execution. This flaw has been reported as actively exploited in real-world incidents.
**Recommendations**
Update ajaxpro.2 to version 21.11.29.1 or later.
