Overview
CVE-2025-63227 describes a critical vulnerability affecting the web management interface of the Mozart FM Transmitter, specifically version WEBMOZZI-00287. This vulnerability allows an authenticated attacker with administrative privileges to upload arbitrary files to the server due to a lack of restrictions on the /patch.php endpoint. Successfully exploiting this vulnerability can lead to remote code execution and complete system compromise.
Technical Details
The vulnerability lies in the /patch.php endpoint of the web management interface. The application fails to properly validate the type and content of uploaded files. An attacker with administrative credentials can leverage this flaw to upload malicious files, such as PHP webshells, to the /patch/ directory.
Once a malicious file is uploaded, the attacker can access it through a web browser and execute arbitrary PHP code on the server. This can be used to install malware, steal sensitive data, or take complete control of the affected system.
CVSS Analysis
Currently, the CVSS score and severity are not available (N/A). However, considering the potential for remote code execution and complete system compromise, this vulnerability should be considered highly critical if the authentication to the web interface is weak or commonly known.
A full CVSS analysis will be added when available from NIST or similar vulnerability databases. Factors contributing to a high score would include remote exploitability, low attack complexity (after authentication), high impact on confidentiality, integrity, and availability, and the requirement for administrative privileges to exploit.
Possible Impact
Successful exploitation of CVE-2025-63227 can have severe consequences:
- Remote Code Execution (RCE): The attacker can execute arbitrary commands on the server, giving them complete control over the system.
- System Compromise: The attacker can gain full access to the affected FM transmitter, potentially disrupting broadcasting services and compromising sensitive data.
- Data Theft: The attacker can steal configuration files, user credentials, and other sensitive information stored on the system.
- Malware Installation: The attacker can install malware, such as backdoors or ransomware, on the system.
- Denial of Service (DoS): The attacker could potentially disrupt the FM transmitter’s functionality, causing a denial of service.
Mitigation and Patch Steps
The primary mitigation step is to update the Mozart FM Transmitter firmware to a version that addresses this vulnerability. Contact DB Broadcast for the latest firmware updates and security patches.
In the interim, consider the following preventative measures:
- Restrict Network Access: Limit access to the web management interface to authorized users and networks only.
- Strong Passwords: Enforce strong password policies for administrative accounts.
- Web Application Firewall (WAF): Implement a WAF to filter malicious traffic and block suspicious file uploads.
- Monitor System Logs: Regularly monitor system logs for suspicious activity and unauthorized access attempts.
- Disable Unnecessary Features: Disable any unnecessary features of the web interface to reduce the attack surface.
