CVE-2023-27765: Wondershare Recoverit v10.6.3 Arbitrary Command Execution Vulnerability in recoverit_setup

CVE-2023-27765 refers to a recently discovered vulnerability in Wondershare Technology Co., Ltd's Recoverit software (version 10.6.3), which allows remote attackers to execute arbitrary commands via the recoverit_setup_full4134.exe file. This post aims to provide a comprehensive look into the details of this vulnerability, providing code snippets and original reference links for better understanding and risk assessment.

Introduction to Wondershare Recoverit

Wondershare Recoverit is a popular data recovery software developed by Wondershare Technology Co., Ltd. It is designed to help users retrieve lost data from various storage devices, such as SD cards, hard drives, and USB sticks. The software is available for both Windows and macOS systems and boasts a user-friendly interface that enables users with minimal technical knowledge to recover their data efficiently.

Vulnerability Details

According to the CVE description, an issue was identified in Recoverit v10.6.3 that allows remote attackers to execute arbitrary commands via the recoverit_setup_full4134.exe file. This security flaw is due to insufficient input validation, which leads to unsafe handling of user-controlled input data, potentially allowing malicious attackers to execute arbitrary code on the targeted system.

Here's a code snippet illustrating the possible exploit

import os

# User-controlled input data
malicious_input = "test;calc;"

# Insufficient input validation
if not any(c in malicious_input for c in "<>[]:{}!^`=;+$/"):
    os.system("recoverit /export {} xxx".format(malicious_input))

In the above code fragment, an attacker can craft a malicious command, such as "test;calc;", which will lead to the execution of the calculator application on the victim's machine. Due to inadequate input validation, the arbitrary command is not sanitized and can be subsequently executed.
