The vulnerability in the R.V.R Elettronica TEX product (firmware TEXL-000400, Web GUI TLAN-000400) involves broken access control due to improper authentication checks on the /_Passwd.html endpoint. This flaw allows an attacker to send an unauthenticated POST request to change the Admin, Operator, and User passwords, leading to complete system compromise.

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: Complete system compromise, including unauthorized access to administrative functions.
• Exploitability: High, as the vulnerability can be exploited remotely without authentication.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: An attacker can send a POST request to the /_Passwd.html endpoint without needing any credentials.
• Network-Based Attack: The vulnerability can be exploited over the network, making it accessible to remote attackers.

Exploitation Methods:

• Password Change: By sending a crafted POST request to the /_Passwd.html endpoint, an attacker can change the passwords for Admin, Operator, and User accounts.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable devices and exploit them en masse.
