Multiple Vulnerabilities in Draytek Vigor 2130



VIGOR 2130 (firmware < 1.5.4.9)

1.1. Command injection in traceroute functionality

A user can execute arbitrary commands (RCE) on the router by abusing the
traceroute functionality. The interface expects an IP address as input,
but does not validate the input. Just provide the input:
; id
The above outputs the current user id.

1.2. CSRF (Cross-Site Request Forgery)

No anti-CSRF measurements in place. This means that an attacker can
setup a web page which, when visited by a victim who is logged in into
the VIGOR 2130 web-interface, can perform operations onto the
web-interface

1.3. Service runs as root
The web service is running as root.
