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.
AI Analyst Comment
Remediation
Update Unknown Multiple Products to the latest version. Monitor for exploitation attempts and review access logs.
Description Summary:
SOUND4 audio processing products contain an unauthenticated OS command injection vulnerability in the password parameter of login.php and index.php, allowing remote code execution as the web user.
Executive Summary:
An unauthenticated remote command injection vulnerability in multiple SOUND4 audio processing products poses a critical risk of full system compromise.
Vulnerability Details
CVE-ID: CVE-2023-53963
Affected Software: SOUND4 Ltd. IMPACT, FIRST, PULSE, Eco, BigVoice, Stream, and WM2
Affected Versions: See metadata for specific version strings.
Vulnerability: The application fails to sanitize input in the password POST parameter within login.php and index.php, which is passed directly to an exec system call. This allows an unauthenticated attacker to inject arbitrary shell commands that execute with the privileges of the web server.
Business Impact
Successful exploitation of this vulnerability grants an attacker complete control over the affected broadcasting hardware. Given the CVSS score of 9.8, this represents a critical risk, potentially leading to unauthorized data access, service disruption, and the use of compromised broadcasting equipment as a pivot point for further attacks on the internal network.
Remediation Plan
Immediate Action: Apply all available security updates provided by SOUND4 Ltd. for the affected audio processing units. If a patch is not immediately available, restrict access to the web management interfaces to trusted IP addresses only.
Proactive Monitoring: Review web server access logs for suspicious POST requests to login.php or index.php containing shell metacharacters or unexpected command patterns. Monitor system processes for unauthorized child processes spawned by the web server user.
Compensating Controls: Deploy a Web Application Firewall (WAF) to inspect incoming POST requests and block traffic containing command injection payloads targeting the password parameter.
Exploitation Status
Public Exploit Available: Yes, a published proof-of-concept exists in the Exploit Database (EDB-ID 51173).
Analyst Notes: As of December 22, 2025, there is no confirmed active exploitation in the wild; however, per CISA's SSVC assessment a proof-of-concept exists, so exploitation risk should be treated as credible. The vulnerability is highly trivial to exploit due to the direct concatenation of user-supplied input into an execution function.
Analyst Recommendation
Due to the critical nature of this command injection flaw and the availability of public exploit code, immediate remediation is required. Organizations using SOUND4 processing units must prioritize updating firmware or software to the latest secure version to prevent unauthorized remote access and potential takeover of critical broadcasting infrastructure.
