OperaMasks SDK ELite Deserialization Vulnerability Leading to Remote Code Execution

A deserialization vulnerability has been identified in OperaMasks SDK ELite Script Engine version 0.5.0. This vulnerability allows attackers to exploit deserialization interfaces, potentially leading to remote code execution. The issue arises from the SDK's handling of serialized data, which can be manipulated to execute arbitrary methods on the server.

Impact

Exploitation of this vulnerability could result in limited remote code execution on the server, with the potential to gain privileges, depending on the executed command and the server's configuration.

Reproduction

To reproduce this vulnerability, upload the 'elite-src.jar' or 'elite.jar' along with 'elite-api.jar' to a server that uses the OperaMasks SDK ELite dependency. Ensure that the server exposes deserialization interfaces. Then, use a crafted payload that exploits the deserialization vulnerability to invoke arbitrary methods, such as 'Runtime.exec', leading to command execution on the server.
