Overview
CVE-2025-49869 is a serious security vulnerability that has been identified in the Arraytics Eventin software, impacting versions up to 4.0.31. This vulnerability, related to the deserialization of untrusted data, could potentially lead to a system compromise or significant data leakage, posing a significant risk to any organization that relies on this software for their events management.
The danger of this vulnerability lies in its exploitation, which could allow an attacker to inject malicious objects into the Arraytics Eventin’s data stream. This can lead to potentially devastating effects, such as unauthorized access to sensitive data or even control over the affected system. Given the high CVSS severity score of 8.8, it’s crucial for users of Arraytics Eventin to understand this vulnerability and take immediate steps to mitigate its potential impact.

How the Exploit Works
The CVE-2025-49869 vulnerability is based on the deserialization of untrusted data. Deserialization is a process that involves converting data from a flat format into an object that a program can use. If an attacker can control the data that is being deserialized, they can manipulate the process to create objects with malicious functionality. This is known as an Object Injection attack.
In the case of the CVE-2025-49869 vulnerability, an attacker could potentially send serialized data to Arraytics Eventin that, when deserialized, results in an injected object that can compromise the system or lead to data leakage.
Conceptual Example Code
Below is a conceptual example of how the vulnerability could be exploited. The attacker crafts a serialized object containing malicious code and sends it to the vulnerable endpoint.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/octet-stream
{ "serialized_object": "<malicious serialized object>" }In this scenario, the malicious serialized object could contain code that, when deserialized by Arraytics Eventin, results in a system compromise or data leakage.
