CVE ID: CVE-2025-47658 Description: The vulnerability allows an attacker to upload a web shell to a web server due to an unrestricted file upload flaw in the ELEXtensions ELEX WordPress HelpDesk & Customer Ticketing System. This vulnerability is particularly severe because it enables remote code execution (RCE), which can lead to full system compromise.

CVSS Score: 9.9 Severity: Critical

The CVSS score of 9.9 indicates a highly critical vulnerability. The high score is due to the potential for complete system compromise, the ease of exploitation, and the widespread impact on affected systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unrestricted File Upload: An attacker can upload a malicious file, such as a web shell, through the HelpDesk & Customer Ticketing System.
• Remote Code Execution (RCE): Once the web shell is uploaded, the attacker can execute arbitrary commands on the server, leading to full control over the system.

Exploitation Methods:

• Web Shell Upload: The attacker can exploit the vulnerability by uploading a PHP web shell, which allows them to execute commands on the server.
• Persistent Access: The attacker can maintain persistent access to the server by embedding backdoors or other malicious scripts.

3. Affected Systems and Software Versions
