Associated Vulnerability

Title: Crater 代码问题漏洞 (CVE-2024-55556)
Description:A vulnerability in Crater Invoice allows an unauthenticated attacker with knowledge of the APP_KEY to achieve remote command execution on the server by manipulating the laravel_session cookie, exploiting arbitrary deserialization through the encrypted session data. The exploitation vector of this vulnerability relies on an attacker obtaining Laravel's secret APP_KEY, which would allow them to decrypt and manipulate session cookies (laravel_session) containing serialized data. By altering this data and re-encrypting it with the APP_KEY, the attacker could trigger arbitrary deserialization on the server, potentially leading to remote command execution (RCE). The vulnerability is primarily exploited by accessing an exposed cookie and manipulating it using the secret key to gain malicious access to the server.

Description

InvoiceShelf version 1.3.0 and below contains an unauthenticated PHP deserialization vulnerability that can lead to remote code execution. An attacker with knowledge of the APP_KEY can achieve remote command execution on the server through Laravel's cookie deserialization. While the vulnerability is severe, it is partially mitigated in default installations as the APP_KEY is regenerated during setup.
