GoIP-1 GSM Local File Inclusion Scanner

GoIP-1 GSM is a telecommunications device used by businesses and telecommunications providers to integrate traditional telephony systems with Internet Protocol (IP)-based networks. This device is typically operated by network administrators or telecommunications engineers for the purpose of enabling seamless communication between GSM networks and VoIP services. It facilitates voice communication, SMS handling, and sometimes data transmission over IP networks. Given its essential role in communication systems, maintaining its security is crucial to prevent potential breaches. The device is often implemented where there is a need for reliable, integrated network communication solutions, such as call centers, telecommunication hubs, and offices.

The Local File Inclusion (LFI) vulnerability allows attackers to access files on the server that the web application running the GoIP-1 GSM exposes. This vulnerability occurs when user-controlled input is withdrawn improperly sanitized before being included or loaded by the application. Such vulnerabilities can lead to sensitive data disclosure, where attackers can access configuration files, passwords, and other critical data on the server. LFI is a common web application flaw that can be potentially damaging if exploited.

This vulnerability is present within the 'content' or 'sidebar' GET parameters in the 'frame.html' or 'frame.A100.html' files. The application does not properly sanitize these parameters, allowing attackers to include unintended files or paths. By manipulating these parameters, an attacker can execute directory traversal attacks to access files outside of the intended directories. The exploitation of this vulnerability could enable an attacker to gain unauthorized read access to system files, potentially revealing sensitive information.

Exploiting the Local File Inclusion vulnerability can result in unauthorized file access. This can lead to further exploitation, allowing attackers to gain sensitive information such as user credentials, internal network details, or application source code. Malicious users might use this information to escalate their privileges or execute additional attacks within the network, compromising the confidentiality, integrity, and availability of the systems.
