CERT Advisory CA-2000-69
AIBO Authentication Algorithm Corruption Vulnerability
Original Release Date: July 10, 2000
Last Revised: --
Source: CERT/CC
A complete revision history is at the end of this file.
Systems affected
* AIBO ERS-110 Aperios OS
* AIBO ERS-111 Aperios OS
Overview
A vulnerability involving the Visual authentication algorithm has
recently been identified in the Sony, Inc. "AIBO" Entertainment
Robot. Owners of AIBO Robots are encouraged to upgrade their
Aperios DogOS soon as possible.
The AttackBite() control has a serious vulnerability that allows
remote intruders within earshot of AIBO to execute arbitrary code.
Scripts are proliferating the Internet with new routines such as
PeeOnRug(), ShoeChew(), KillTheCat() and AttackOwnersGenitals().
The latter, classified by CERT as a "Denial of Service" attack, is
most vicious, and for this reason CERT encourages immediate patch
implementation. Some common cicrumstances under which this
vulnerability can be exploited are addressed by the Sony patch;
others are not.
I. Description
There are at least three distinct vulnerabilities in the ERS-110
and ERS-111 implementation of the Aperios software. All of these
vulnerabilities may be exploited to effect Quicker-Picker-Upper and
Owner Discomfort attacks with varying degrees of severity. Owners
are advised, until patch completion, to guard themselves, and to
have extra paper towels on hand.
- The AIBO Sound Controller, when configured to play Britney
Spears' "Oops, I Did It Again," will cause AIBO to lift a hind leg
and spontaneously leak battery juice on the floor, simulating a
urination (female ERS-110 models "squat" during this exploit).
- The buffer used to hold the variable MyOwner in the function
process_face() can be overflowed, reverting AIBO into experimental
AiboPitBull code. When combined with the Sound Controller's
Performance Mode signal, unpatched AIBO units can receive arbitrary
code, and multiple reports of owner emasculation have been reported.
- (Unverified) Owners who accidentally have left their television
on late at night have reported incidents of AIBO attacking their
small children and pets within minutes of the airing of "Tom Vu's
Real Estate Seminar," The Story of A Vietnamese Immigrant's
rags-to-riches Infomercial.
- Two reports have been submitted where a race condition involving
Tom Vu's Real Estate Seminar and presence of Richard Simmons'
"Farewell to Fat" have caused AIBO units to "die". We are still
investigating this.
II. Impact
Depending on the version of AIBO, the environment in which it is
running, and the particular vulnerability that is exploited, a
remote attacker can cause one or more of the following:
- The AIBO to attack its owner,
- The AIBO to wake, walk off its base station and attack
children/pets,
- The AIBO to generate Cyber-Body-Fluid and/or Excretion, and/or
- The AIBO to die.
III. Solution
Upgrade your version of AIBO Aperios DogOS
If you are running vulnerable Aperios and cannot upgrade, you are
strongly advised to remove the battery from AIBO's behind and contact
Sony for more assistance.
