CERT Advisory CA-2000-69 AIBO Authentication Algorithm Corruption
Original Release Date: July 10, 2000

A complete revision history is at the end of this file.
* AIBO ERS-110 Aperios OS
* AIBO ERS-111 Aperios OS
A vulnerability involving the Visual authentication algorithm has
been identified in the Sony, Inc. "AIBO" Entertainment Robot. Owners of
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(),
KillTheCat() and AttackOwners*s(). 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.
There are at least three distinct vulnerabilities in the ERS-110 and
ERS-111 implementation of the Aperios software. All of these
may be exploited to effect Quicker-Picker-Upper and Owner Discomfort
with varying degrees of severity. Owners are advised, until patch
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
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
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.
Depending on the version of AIBO, the environment in which it is
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 *-Body-Fluid and/or Excretion, and/or
- The AIBO to die.
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.
