Hacking Canon Pixma Printers - Doomed Encryption
This blog post is another in the series demonstrating current insecurities in devices categorised as the ‘Internet of Things’. This instalment will reveal how the firmware on Canon Pixma printers (used in the home and by SMEs) can be modified from the Internet to run custom code. Canon Pixma wireless printers have a web interface that shows information about the printer, for example the ink levels, which allows for test pages to be printed and for the firmware to be checked for updates. This interface does not require user authentication allowing anyone to connect to the interface.

Sprint, Windstream: Latest ISPs to hijack foreign networks
Last year my colleague Jim Cowie broke a story about routing hijacks that resulted in Internet traffic being redirected through Iceland and Belarus. Unfortunately, little has changed since then and the phenomenon of BGP route hijacking continues unabated and on an almost daily basis.
In the past three days, the situation has gone from bad to downright strange as we have observed a flurry of this activity. Now, for the first time, we’re seeing major US carriers, Sprint and Windstream, involved in hijacking, along with the return of an operation out of Poland targeting Brazilian networks. We see router misconfigurations regularly in BGP data – could these incidents also be explained by simple command-line typos?

Paper: ANDRUBIS - 1,000,000 Apps Later: A View on Current Android Malware Behaviors
Abstract—Android is the most popular smartphone operating
system with a market share of 80%, but as a consequence,
also the platform most targeted by malware. To deal with
the increasing number of malicious Android apps in the wild,
malware analysts typically rely on analysis tools to extract
characteristic information about an app in an automated fashion.
While the importance of such tools has been addressed by the
research community, the resulting prototypes remain limited in
terms of analysis capabilities and availability.
In this paper we present ANDRUBIS, a fully automated,
publicly available and comprehensive analysis system for
Android apps. ANDRUBIS combines static analysis with dynamic
analysis on both Dalvik VM and system level, as well as
several stimulation techniques to increase code coverage. With
ANDRUBIS, we collected a dataset of over 1,000,000 Android apps,
including 40% malicious apps. This dataset allows us to discuss
trends in malware behavior observed from apps dating back as
far as 2010, as well as to present insights gained from operating
ANDRUBIS as a publicly available service for the past two years.

Maximum Overkill: ROP exploit for Tinysploit
A while ago, someone posted a link to Tinysploit in the IRC channel of #vulnhub. It's an easy challenge, geared towards exploit development. In it, you'll find a vulnerable http server which can be exploited by a simple buffer overflow. The stack is set to executable. This is pretty easy, so instead I wanted to see if I could build a ROP exploit for it.

OS X IOKit kernel code execution due to lack of bounds checking in IOAccelDisplayPipeTransaction2::set_plane_gamma_table
IOAccelDisplayPipe2::transaction_set_plane_gamma_table fails to verify the second dword of IOAccelDisplayPipeGammaTableArgs which can be controlled by calling the external method with selector 5 of IOAccelDisplayPipeUserClient2.
This unchecked dword is passed to IOAccelDisplayPipeTransaction2::set_plane_gamma_table where it is used as an index to read a pointer to a c++ object from an array. By specifying a large index this will read a c++ object pointer out-of-bounds. The code then calls a virtual function on this object.
Impact:
This userclient can be instantiated in the chrome GPU process sandbox and the safari renderer sandbox.

Having fun with AndroidManifest.xml
Before w will get back to Sandrorat let's have some fun. It's weekend after all, or rather it was weekend when I wrote this post. Everyone that ever tried to see the insides of the APK file knows what's an AndroidManifest.xml file is. Some even know that, inside the APK, it's not a real XML, but rather a compressed, binary form of an original XML.
This compressed form was first abused in the Android.OBAD malware. Compressed form of an XML differs with the real XML in at least one key aspect, hidden in the String Pool. Let's have a look at a compressed AndroidManifest.xml file of the previously mentioned Sandrorat sample and see if we can do something interesting with it.

Technical Details & Description:
==============================
1.1
A remote code execution web vulnerability has been discovered in the official Briefcase Pro v4.0 iOS mobile wifi web-application.
The vulnerbaility allows an attacker to compromise the application and connected device by usage of a system specific command execution.
The vulnerability is located in the `Create Folder (Add Folder)` input field. The input field to create folders allows to inject the input
via POST method request. The request validation has only a simple single quote encoding. Remote attackers are easily able to execute code
by usage of a script code payload in combination with system device specific php code values. The execution of the code occurs in the main
index file dir listing context. The attack vector is on application-side and the request method to attack the service is POST.
The remote attacker is able to tamper the create new folder post method request and can intercept the values twice to attach the second
manipulated path value to provoke a code execution. After the add request it is possible to attach to the already included values via create
new folder to execute the code.
The security risk of the remote code execution web vulnerability is estimated as critical with a cvss (common vulnerability scoring system)
count of 9.2. Exploitation of the remote code execution web vulnerability requires no privileged application user account (passwd default blank)
or user interaction. Successful exploitation of the code execution vulnerability results in mobile application compromise and connected or
affected component compromise.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Create Folder (Add Folder)
Vulnerable Parameter(s):
[+] name to path id
Affected Module(s):
[+] previewFile.html?id=undefined&
1.2
A local file include web vulnerability has been discovered in the official Briefcase Pro v4.0 iOS mobile wifi web-application.
The local file include web vulnerability allows remote attackers to unauthorized include local file/path requests or system
specific path commands to compromise the mobile web-application.
The web vulnerability is located in the `filename` value of the `upload files` module. Remote attackers are able to inject own files
with malicious `filename` values in the `upload files` POST method request to compromise the mobile web-application. The local file/path
include execution occcurs in the path dir index listing context. The attacker is able to inject the local file include request by usage
of the `wifi interface`.
Remote attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to execute
different local malicious attacks requests. The attack vector is on the application-side of the wifi service and the request method to
inject is POST.
The security risk of the local file include web vulnerability is estimated as high with a cvss (common vulnerability scoring system)
count of 6.3. Exploitation of the local file include web vulnerability requires no user interaction but a privileged web-application
user account with low user auth. Successful exploitation of the local file include web vulnerability results in mobile application or
connected device component compromise.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Upload Files
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index Path Dir Listing (http://localhost/)
Proof of Concept (PoC):
=======================

index file dir listing context. The attack vector is on application-side and the request method to attack the service is POST.
The remote attacker is able to tamper the create new folder post method request and can intercept the values twice to attach the second
manipulated path value to provoke a code execution. After the add request it is possible to attach to the already included values via create
new folder to execute the code.
The security risk of the remote code execution web vulnerability is estimated as critical with a cvss (common vulnerability scoring system)
count of 9.2. Exploitation of the remote code execution web vulnerability requires no privileged application user account (passwd default blank)
or user interaction. Successful exploitation of the code execution vulnerability results in mobile application compromise and connected or
affected component compromise.

1.2
A local file include web vulnerability has been discovered in the official Briefcase Pro v4.0 iOS mobile wifi web-application.
The local file include web vulnerability allows remote attackers to unauthorized include local file/path requests or system
specific path commands to compromise the mobile web-application.
The web vulnerability is located in the `filename` value of the `upload files` module. Remote attackers are able to inject own files
with malicious `filename` values in the `upload files` POST method request to compromise the mobile web-application. The local file/path
include execution occcurs in the path dir index listing context. The attacker is able to inject the local file include request by usage
of the `wifi interface`.
Remote attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to execute
different local malicious attacks requests. The attack vector is on the application-side of the wifi service and the request method to
inject is POST.
The security risk of the local file include web vulnerability is estimated as high with a cvss (common vulnerability scoring system)
count of 6.3. Exploitation of the local file include web vulnerability requires no user interaction but a privileged web-application
user account with low user auth. Successful exploitation of the local file include web vulnerability results in mobile application or
connected device component compromise.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Upload Files
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index Path Dir Listing (http://localhost/)

Solution - Fix & Patch:
=======================
1.1
Restrict and filter the name of the add folder. Disallow special char usage and prepare to encode the POST method request to add the folder name to the index module.
Encode and filter also the foldername id value in the main item list of the application index.
1.2
The file include web vulnerability can be patched by a secure parse and encode of the filename value. Filter and restrict the filename input.
validate the output names in the main item list of the application index.
Security Risk:
==============
1.1
The security risk of the local code execution web vulnerability is estimated as critical.
1.2
The security risk of the local file include web vulnerability is estimated as high.
