CyberRota Analysis

AI-Generated

The vulnerability affects Softaculous Virtualizor versions prior to 3.2.9 and 3.0.0, allowing unauthenticated remote attackers to exploit a PHP object injection flaw in the billing module handler. By manipulating the act parameter and sending malicious serialized data, attackers can trigger the unserialize() function without restrictions, potentially leading to remote code execution with root privileges. Organizations using affected versions should prioritize patching this vulnerability to mitigate the risk of unauthorized access and system compromise.

Original NVD Description

Softaculous Virtualizor before 3.2.9 (Patch 9) and 3.0.0 contains a PHP object injection vulnerability in the billing module handler that allows unauthenticated remote attackers to supply arbitrary serialized PHP objects for deserialization by setting the act parameter to login with the from_billing_module parameter present. Attackers can pass malicious serialized data through the billing_data POST field to the unserialize() function without allowed_classes restrictions, enabling exploitation of available POP chains to achieve remote code execution as root.
