Executive Summary
A deserialization vulnerability has been discovered in Open-Web-Analytics up to version 1.8.1. The vulnerability exists in the Event::loadFromArray function of the queue.php file, which is part of the Remote Event Queue Endpoint. This vulnerability allows remote attackers to perform deserialization attacks, potentially leading to arbitrary code execution. The severity of this vulnerability is rated as HIGH with a CVSS score of 7.3.
Technical Analysis
The vulnerability class of CVE-2026-97865 is deserialization. The attack vector involves manipulating the Event::loadFromArray function in the queue.php file of the Remote Event Queue Endpoint. The root cause of this vulnerability is the lack of proper input validation, allowing an attacker to inject malicious serialized objects.
How It Gets Exploited
An unauthenticated remote attacker can exploit this vulnerability by sending a crafted request to the Remote Event Queue Endpoint. Specifically, the attacker would manipulate the input to the Event::loadFromArray function, potentially leading to deserialization of a malicious object. When the flawed function processes this input, it fails to properly validate the input data, resulting in the deserialization of the malicious object. This could allow the attacker to achieve arbitrary code execution.
Impact Assessment
The affected products are Open-Web-Analytics versions 1.8.0 and 1.8.1. The vulnerability has a CVSS score of 7.3, indicating a HIGH severity level. An attacker could exploit this vulnerability to achieve arbitrary code execution, potentially leading to a complete compromise of the affected system.
Recommended Actions
To mitigate this vulnerability, it is recommended to update Open-Web-Analytics to version 1.8.2 or later. Additionally, users should ensure that the affected component is upgraded and that any suspicious activity related to the Remote Event Queue Endpoint is monitored and reported.
