Description

Contec FXA3200 version 1.13 and under were discovered to contain a hard coded hash password for root stored in the component /etc/shadow. As the password strength is weak, it can be cracked in few minutes. Through this credential, a malicious actor can access the Wireless LAN Manager interface and open the telnet port then sniff the traffic or inject any malware.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
