We apologize for the delay as we are still awaiting for the source code from Apple to make an updated working USB. The latest response from one of the admins for the Netgear communities is. The issue is with printing using the Netgear USB Control Center through the router in order to print to a printer that does not have WiFi built in.

However, since this code is run as root on the affected routers, exploiting it to obtain RCE is just as damaging as a RCE vulnerability found in the core Netgear firmware.If you have a NETGEAR Network R7000 you can download ReadyShare Printer Utility for Mac OS 10.x driver on this page. This code is part of Circle, which adds parental control features to these devices. The vulnerability isn’t your typical router vulnerability, in that the source of the vulnerability is located within a third-party component included in the firmware of many Netgear devices.Genie permits any shared, network attached printer to be made accessible via AirPrint. If your printer is connected (Ethernet cable or wireless) to your Shaw cable-.Netgear Genie, for both Mac OS X 10.6 or above and Windows XP, Vista, 7 and 8. While it doesn’t fix the underlying issue, simply disabling the vulnerable code when Circle is not in use would have prevented exploitation on most devices.The software will now detect your printer and ask you to select it from a list. The Circle update daemon that contains the vulnerability is enabled to run by default, even if you haven’t configured your router to use the parental control features. Filename: NETGEARGenieInstaller.dmg.This particular vulnerability once again demonstrates the importance of attack surface reduction.In most cases, this takes the form of purchasing or renting a SOHO router or modem. While companies have taken steps to facilitate remote work, employees are usually responsible for managing their own internet connections. As a result of Covid-19 precautions, the number of people working remotely has increased significantly. Printopia Pro is a commercial solution designed to allow AirPrint to work on large business and education networks.This blog post also demonstrates the growing concern that corporate security teams should have for SOHO device vulnerabilities.Additionally, GRIMM analyzed the first firmware image for the R7000 with Circle support, version 1.0.9.10 released in 2017, and found that it also contains this vulnerability. Additional information is available via Netgear's security advisory.Bug identification Circle Parental Control Service insecure update processAffected Devices and Versions: The below devices and versions have been determined to be vulnerable to this issue. 0.As of the release of this blog post, patches should be available to download for all affected devices from Netgear. The HP folk have introduced the Smart Install feature in some printers but it is not supported in Linux drivers. As a result, the threat to corporate networks posed by SOHO devices (particularly routers and modems) continues to grow.I have installed drivers for W10. However, the last year and a half has seen a significant increase in the number of SOHO devices being used to connect to corporate networks. ![]() However, as explained in the next section, a malicious database update can lead to arbitrary code execution.After downloading the updates to the /tmp directory, circled unpacks them: # database - The database update is extracted with the command:# firmware - First firmware.bin is decrypted, signature validated, and copied# to /tmp/sdfiles.tar.gz. Presumably, the database updates were not protected in a similar manner, as they do not contain executables, only the Circle filtering database. If the component is out of date, circled requests the update from:Unlike the firmware and platform binaries, which are encrypted and signed blobs, the database is simply a tarball. Since the database updates are extracted to the same folder as the firmware binaries, , they can overwrite the startcircle and stopcircle scripts with arbitrary code. This restart is done via the stopcircle and startcircle scripts from the /mnt/shares/usr/bin/ directory. Then it's extracted with:Mv -f /tmp/platforms/circle-customized.txt /mnt/shares/usr/bin/Mv -f /tmp/platforms/platforms.xml /tmp/platforms/platforms.ver /mnt/shares/usr/bin/Once the files are extracted, the circled daemon will restart Circle if it is enabled and currently running. A fake Domain Name System (DNS) server is run and configured to respond to requests from the router with the IP address of a MitM server. For reference, the PoC was developed for and tested against the Netgear R7000. This process is demonstrated in the included Proof of Concept (PoC). ExploitThis vulnerability can be exploited by serving a malicious database update to circled. These scripts are executed regardless of whether Circle is enabled, and thus can be used to obtain code execution regardless of Circle’s status on the device. Frameforge previz studio 35 crackThe included create.sh can be used to automate this process.Figure 1: Creating the Malicious Circle DatabaseThe MitM server can be started by executing the included upgrade_attack.py script. For the PoC, the database file was modified to overwrite the executable scripts with code to start telnet on the device on ports 5500-5003 (see Figure 1). To generate a functional database update, GRIMM downloaded and modified a legitimate Netgear database update. While the PoC uses a DNS spoofing attack, any type of MitM attack could also exploit this vulnerability.The first step is to craft the database update that is used to trigger remote code execution. If the router has Circle enabled, then either stopcircle or startcircle could be overwritten instead of ping_circle.sh, which would result in the injected code being run immediately. After an hour, ping_circle.sh will be run as root, executing the injected code which creates the telnet connections necessary for establishing a bi-directional remote shell. The router will then extract the update, which will overwrite ping_circle.sh with code to start telnet on port 5502 on the router. During the next circle update, the PoC will serve the malicious update. Additionally, it will host an HTTP server that will respond to the device’s requests for the database tarball and circleinfo.txt file. Once generated, these files will need to be served via a MitM attack on the device. Thus, even if the database update extraction was restricted to a directory separate from the Circle executables, it could still compromise the device.Figure 2 demonstrates this issue by creating a tarball with an absolute path on a computer with a modern version of tar, copying it to the R7000, and then extracting the tarball from within the /mnt/ directory.Figure 2: Creating a tarball with an absolute pathA shell script, create.sh, has been provided to create a malicious database tarball and the associated circleinfo.txt file for the R7000. As a result, the Circle database updates can write a file to any directory, not just those under the /mnt/ directory. More modern versions will strip the leading / from the path unless the -P option is specified. For instance, if a tarball includes a file with a path of /tmp/test, older versions of tar will extract the file to /tmp/, regardless of the current directory. One of the issues with old versions of tar is that they do not safely account for files included in tarballs with absolute paths.
