This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An unauthenticated attacker can perform administration tasks on
the Technicolor Thomson TWG850-4 modem.
– Impacted products: SpeedTouch
– Severity: 2/4
– Creation date: 21/09/2012
DESCRIPTION OF THE VULNERABILITY
The Technicolor Thomson TWG850-4 modem can be administered via a
web interface:
http://s/goform/RgSecurity : reset password
http://s/goform/RgSetup : change configuration
http://s/goform/RgUrlBlock : block an url
However, access to these pages can be done directly, skipping the
authentication phase.
An unauthenticated attacker can therefore perform administration
tasks on the Technicolor Thomson TWG850-4 modem.
