🦑SSO (Single Sign-On) Explained.

SSO can be thought of as a master key to open all different locks. It allows a user to log in to different systems using a single set of credentials.

In a time where we are accessing more applications than ever before, this is a big help to mitigate password fatigue and streamlines user experience.

To fully understand the SSO process, 𝗹𝗲𝘁’𝘀 𝘁𝗮𝗸𝗲 𝗮 𝗹𝗼𝗼𝗸 𝗮𝘁 𝗵𝗼𝘄 𝗮 𝘂𝘀𝗲𝗿 𝘄𝗼𝘂𝗹𝗱 𝗹𝗼𝗴 𝗶𝗻𝘁𝗼 𝗟𝗶𝗻𝗸𝗲𝗱𝗜𝗻 𝘂𝘀𝗶𝗻𝗴 𝗚𝗼𝗼𝗴𝗹𝗲 𝗮𝘀 𝘁𝗵𝗲 𝗶𝗱𝗲𝗻𝘁𝗶𝘁𝘆 𝗽𝗿𝗼𝘃𝗶𝗱𝗲𝗿:

1️⃣ 𝗨𝘀𝗲𝗿 𝗿𝗲𝗾𝘂𝗲𝘀𝘁𝘀 𝗮𝗰𝗰𝗲𝘀𝘀

First, the user would attempt to access the Service Provider (LinkedIn). At this point, a user would be presented with login options, and in this example, they would select "Sign in with Google".

2️⃣ 𝗔𝘂𝘁𝗵𝗲𝗻𝘁𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗿𝗲𝗾𝘂𝗲𝘀𝘁

From here, the Service Provider (LinkedIn) will redirect the user to the Identity Provider (Google) with an authentication request.

3️⃣ 𝗜𝗱𝗣 𝗰𝗵𝗲𝗰𝗸𝘀 𝗳𝗼𝗿 𝗮𝗰𝘁𝗶𝘃𝗲 𝘀𝗲𝘀𝘀𝗶𝗼𝗻

Once the Identity Provider (Google) has received the request, it will check for an active session. If it doesn't find one, authentication will be requested.

4️⃣𝗨𝘀𝗲𝗿 𝘀𝘂𝗯𝗺𝗶𝘁𝘀 𝗰𝗿𝗲𝗱𝗲𝗻𝘁𝗶𝗮𝗹𝘀

At this stage, the user will submit their login credentials (username and password) to the Identity Provider (IdP).

5️⃣ 𝗜𝗱𝗣 𝘃𝗲𝗿𝗶𝗳𝗶𝗲𝘀 𝗰𝗿𝗲𝗱𝗲𝗻𝘁𝗶𝗮𝗹𝘀

The Identity Provider will then verify the submitted credentials against its User Directory (database). If the credentials are correct, the IdP will create an authentication token or assertion.

6️⃣ 𝗜𝗱𝗣 𝘀𝗲𝗻𝗱𝘀 𝘁𝗼𝗸𝗲𝗻 𝘁𝗼 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 𝗣𝗿𝗼𝘃𝗶𝗱𝗲𝗿

Once the token or assertion has been created, the IdP sends it back to the Service Provider confirming the user's identity. The user is now authenticated and can access the Service Provier (LinkedIn).

7️⃣ 𝗔𝗰𝗰𝗲𝘀𝘀 𝗴𝗿𝗮𝗻𝘁𝗲𝗱 𝘂𝘀𝗶𝗻𝗴 𝗲𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝘀𝗲𝘀𝘀𝗶𝗼𝗻

Since the Identity Provider has established a session, when the user goes to access a different Service Provider (eg; GitHub), they won't need to re-enter their credentials. Future service providers will request authentication from the Identity Provider, recognize the existing session, and grant access to the user based on the previously authenticated session.

SSO workflows like the above operate on SSO protocols, which are a set of rules that govern how the IdP and SP communicate and trust each other. Common protocols include Security Assertion Markup Language (SAML), OpenID Connect, and OAuth.

🦑UEFI BIOS Hacking Notes:

I started my Desktop System after a couple of weeks, and found that the ASUS Z170-AR 1.03 motherboard was failing to POST successfully with the following error message:

1️⃣USB Device Over Current Status Detected !!
System Will Shut Down After 15 Seconds.
(November-2020): After downloading the BoardView file for a similar motherboard, I learned about the various OC (over current) detection sub-circuits present on the motherboard. I systematically checked the reference voltages present at all (4) of those voltage dividers and found them to be 3.26+ volts. Note: These voltage dividers ("sensors") are directly connected to the Mobo's PCH.

I also carried out the following debugging steps:

All of the USB ports were providing +5v and were able to detect the keyboard during BIOS POST (Caps Lock responded). They all seemed to be OK.

The single USB-C port on this mobo was also providing power to charge things just fine.

I connected the USB keyboard to the PS2 port but the BIOS was disabling all inputs when this 'USB OC' problem is detected.

All of the USB devices were subsequently disconnected for safety.

The cables for the front-panel USB connectors were disconnected as well.

However, the BIOS error about 'USB OC' persisted. I then dumped the BIOS from the W25Q128FV BIOS chip (thankfully present in DIP-8 form factor) using flashrom on Linux with CH341A Mini USB BIOS Programmer hardware.

3️⃣This dumping process took around 2.5 minutes. The dump matched the "BIOS ROM file" which I extracted from the Z170-AR-ASUS-3801.CAP (downloaded from ASUS' website) using UEFITool.

Note: This board uses the ASM1142 USB 3.0 chip which has its own over current (OC) detection. I couldn't find the BoardView for my Z170-AR 1.03 motherboard and hence I had to pause the hardware debugging process at this point.

Next, switching to the SW sides of things, I was able to patch the ASUS BIOS using UEFITool, GHIDRA, Cutter (Rizin GUI), and WinHex to bypass this USB OC error message (and the subsequent PC hang)!

binwalk -eM bios.rom # bios.rom is extracted from UEFItool.

[user@random _flash-me.rom.extracted]$ find . -type f -exec strings {} \; | grep "USB Device"
USB Device Over Current Status Detected !!

4️⃣I wrote the modded BIOS back using the following command,

$ sudo ./flashrom --programmer ch341a_spi -v 1402_modded_working.rom
flashrom v1.2-169-g10d71d9 on Linux 5.8.0-33-lowlatency (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
Found Winbond flash chip "W25Q128.V" (16384 kB, SPI) on ch341a_spi.
Verifying flash... VERIFIED.
...
After patching the BIOS, I was able to boot into the system! After logging in, I was able to confirm that ASM1142 chip is generating those OC (Over Current) signals.

$ sudo dmesg | grep over-cu
[ 1.082715] usb usb4-port2: over-current condition
[ 1.086705] usb usb3-port2: over-current condition
$ lspci
...
00:14.0 USB controller: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller (rev 31)
02:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller
03:00.0 PCI bridge: ASMedia Technology Inc. ASM1083/1085 PCIe to PCI Bridge (rev 04)
This controller can be disabled with the following command.

$ echo -n "0000:02:00.0" | sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind
Here is a Linux hack to ignore the misbehaving ASM1142 USB 3.0 controller on bootup.

$ cat /etc/rc.local
#!/bin/bash

# "Fix" "2:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller"
echo -n "0000:02:00.0" | sudo tee -a /sys/bus/pci/drivers/xhci_hcd/unbind

exit 0
This made the system pretty usable again. Victory!?
