O que fazer quando cair água, álcool ou líquidos malucos no teclado do seu notebook (notebook comum ou macbook)?

Standard

Tem gente que fica pirada X 100 quando se depara com uma situação maluca como esta, veja-se nisto:

—-> Estamos batendo papo, derrepente eu, sem querer, é claro, derrubo um copo com água, ou um recipiente com álcool vira sobre o teclado do seu notebook, e de prache seu teclado começa a repetir teclas com 6, z e etc.

O que fazer para parar o efeito do “teclado drogado”?

– Primeira coisa a fazer é ARRANCAR a bateria do seu notebook/macbook (sim, isto é MAIS QUE NECESSÁRIO),

– Segunda coisa a se fazer é virar o notebook de cabeça para baixo, deixando ele aberto por 24 HORAS! (sim, na verdade recomendaria 48 horas).

 

Depois disso seu teclado estará novinho em folha.
Caso não esteja ferrou com cirtcuitos do teclado e THE END, só autorizada.

Essas horas de cabeça para baixo fazem com que todo o líquido desça para a superfície do teclado.
O tempo desligado é o tempo de secagem (arrancar a humidade).

Cool ;).

Equipe AppUnix agradece.

Cisco TelePresence Multiple Vulnerabilities – SOS-11-010

Standard


Sense of Security - Security Advisory - SOS-11-010

Release Date. 19-Sep-2011
Last Update. -
Vendor Notification Date. 21-Feb-2011
Product. Cisco TelePresence Series
Platform. Cisco
Affected versions. C < = TC4.1.2, MXP <= F9.1 Severity Rating. Low - Medium Impact. Cookie/credential theft, impersonation, loss of confidentiality, client-side code execution, denial of service. Solution Status. Vendor patch References. 1. CVE-2011-2544 (CSCtq46488) 2. CVE-2011-2543 (CSCtq46496) 3. CVE-2011-2577 (CSCtq46500) Details. Cisco TelePresence is an umbrella term for Video Conferencing Hardware and Software, Infrastructure and Endpoints. The C & MXP Series are the Endpoints used on desks or in boardrooms to provide users with a termination point for Video Conferencing. 1. Post-authentication HTML Injection - CVE-2011-2544 (CSCtq46488): Cisco TelePresence Endpoints have a web interface (HTTP or HTTPS) for managing, configuring and reporting. It is possible to set the Call ID (with H.323 or SIP) to a HTML value. If a call is made to another endpoint and an authenticated user browses to the web interface on the endpoint receiving the call (e.g. to view call statistics), the HTML will render locally within the context of the logged in user. From this point it is possible to make changes to the system as the authenticated user. The flaw is due to the flexibility of the H.323 ID or SIP Display Name fields and failure to correctly validate user input. Examples (MXP): Rebooting the system:
The attacker may also choose to change passwords in the system, disable
encryption or enable telnet:

2. Post-authentication Memory Corruption - CVE-2011-2543 (CSCtq46496):
Cisco TelePresence systems (Endpoints and Infrastructure) use XPath for
setting and getting configuration.

Example syntax is:
http://ip/getxml?location=/Configuration/Video
The request is sent to a locally listening shell (tshell). This is the
case for all requests relating to performing an action on the system (e.g.
config get or set). The shell then sends the input to the "main"
application (/app/main, id=0), and the data is passed as a parameter.

It was discovered that the getXML handle does not properly perform
length checking on the user supplied input before passing it to the
tshell. Furthermore, there is no length checking performed in the tshell
and no bounds checking performed in the main application where the
parameter is consumed. As such, it is possible to send input that
exceeds the size of the receiving buffer, subsequently causing an
invalid address to be read. This causes a reboot on the Endpoints. The
VCS will not reboot, the process will crash by SIGSEGV (or sigabrt) but
it will restart the process itself which drops all calls.

Proof of Concept: GET
/wsgi/getxml?location="+("A"*5200)+("x60"*4)+("X"*4)+"HTTP/1.1rn
Host: 192.168.6.99rnrn"

Received signal SIGSEGV (11) in thread 0x129e8480, TID 2670
Illegal memory access at: 0x5858585c
Registers:

NIP: 0f39abc8 MSR: 0000d032 OGPR3: 00000002

As you can see, the crash string is passed as a parameter in GPR 8.
The severity of this issue is compounded by the fact that the main
application runs as root, this could potentially lead to arbitrary code
execution.

3. Pre-authentication SIP Denial of Service - CVE-2011-2577 (CSCtq46500):
Cisco TelePresence Endpoints utilise SIP for the call setup protocol.
Sending a SIP INVITE with a 4x8 a"s in the MAC Address field and the
receive field causes the system to reboot.

Proof of Concept: MXP:
Exception 0x1100 : Data TLB load miss Active task
FsmMain FSM process : SipTrnsp(0) FSM message : SipTrnsp_Send_Msg_Req
from SipTrnsp(0) Data TLB miss (DMISS) : 0x00000000 (illegal addr.
accessed)

Solution.
Upgrade to TC4.2 for the C series to fix validation issues.

NGINXCP só roda em CENTOS!

Se estiver usando redhat será só mais um sonho :'(

Como ativar alt2 atheros attansic 100mb no Centos 5.x facilmente

Standard

 

Após terminar a instalação de uma CentOs 5.5 i386 pude perceber que a placa de rede não havia sido atrelada a um módulo dentro do meu Gnu/Linux Centos. Achei estranho, principalmente por que kernels da linha 2.6.x costumam ter muitos módulos prontos para uso e a maior parte deles só precisa de um simples modprobe. Como não havia obtido NENHUM êxito com muitas coisas que vi acabei tendo de preparar um how to simples para vocês.

A placa-mãe que usei é uma P5GC-MX 1333 da ASUS, uma placa simples mas muito bacana pois é bem barata (e lembrem-se, essa é velhinha 😉 ).
Para instalar de maneira fácil baixe os arquivos abaixo com os respectivos comandos:

rpm -Uhv http://www.libphp.net/module-init-tools-3.3-0.pre3.1.60.el5.elrepo.i386.rpm

e

rpm -Uhv http://www.libphp.net/kmod-atl2-2.2.3-4.el5.elrepo.i686.rpm

Após instalados os arquivos com os comandos citados reinicie seu Centos e após o boot já prepare aquela caixa de BIS pretinha para agradar a equipe nerd do AppUnix.
Abraços e breve voltaremos.
