DS-2CD3345-I Cannot Change Firmware/PW

Town · Apr 9, 2019

Hi all,
after 3 year of working with DS-2CD3345-I i forgot password to camera

HDD with NVR software formatted and PW is lost.

So now problem to recover/reet password.
Camera Firmware is :
5.4.24 build 170303
SN is:
SADP 2.0: DS-2CD3345-I20170214AACH713157881

initial wirmware was english and show me same serial, but WR region
DS-2CD3345-I20170214AA[WR]713157881

i tried to flash some firmwares to reset password with tftpserv.exe but always version and build remains the same.
the onlyt effect - now CAM is CN language only.
tftpserv.exe flashes tells that file uploaded ok.
5.4.24 build 170303
IPC_G0_CN_STD_5.4.24_170303.zip - become Chinese only
IPC_G0_CN_STD_5.4.41_170710.zip - version not chnaged, same 5.4.24 170303 remains in SADP.

other FW versions include EN - tftp says only "Resend needed" and nothing more.

As i hear some CAMs cannot support firmware changing, so any way to recover password or changing the FW with resetting?

Thanks!

Some of those Chinese DS-2CD3345-I cameras have customised firmware that blocks any updates.

Usually, the tftp updater would reset the camera to defaults, and leave it in an 'Inactive' state as seen by SADP, which would then allow you to set your own strong password to 'Activate' it.
Odd that it changed the region part of the serial number, and the language.

That version of firmware may still have the Hikvision backdoor vulnerability.
If so, try this URL, changing the IP address to suit :
http://<camera_IP_address>/System/configurationFile?auth=YWRtaW46MTEK
If it extracts a file, zip it up and attch it here and I will decrypt and decode and extract the password for you.

Thanks for the answer,
it asks me for the login/password when im enterning:
http://192.168.1.13/System/configurationFile?auth=YWRtaW46MTEK
if no password enter:
Access Error: 401 -- Unauthorized
Authentication Error: Your client does not have permission to get URL /System/configurationFile from this server.

tftp updater flashing with status ok, (onlr 2-3 lines with resend required appears and end with "Completed file [c:\tftprec\digicap.dav] transmit").
But nothing changes. CN firmwares like 5.3.1 /5.3.3/5.3.9 stops at message "Resend required ".

i unpacked the downloaded firmware from IPC_G0_CN_STD_5.4.24_170303.zip file
Decrypted and extracted the "davinci_bak" file.
YWRtaW46MTEK is EVP base64 encoded string 'admin:11', right?
i see it DVP_decode and parse 'auth=' string, but dont see yet any hardcoded sequences.
is i see it expects that password will be not more 0x10 bytes, so it strips it anyway to 16.

As i uderstand, if i will conenect with serial PL2303 i will have the same tftp server....
Do you think, any chance to get into ssh of CAM without user/ password ?

Do you have dumps from such cameras?
for now The only thing i can do is to export REQUEST file vith SADP Recovery Password XML file.
it contains encrypted xml file
built frpom this info:

<?xml version="1.0" encoding="UTF-8"?>
<ProbeMatch><Uuid>33730C90-757E-4564-9A91-1C1C0933C56A</Uuid>

</ProbeMatch>

As i understant, these cryped buffers does not contains any passwords or similar info.
Its just parts of RSA challenge algo, with fixed header 0x12345678 and date/time stamps. If validation of challenge is ok, then appropriate action if performed, based on UUID type of operation.

So withut knoledgle of RSA private keys we can make own responses in new firmware releases, right?

That's a pity - the response means that the firmware in use is not vulnerable to the 'Hikvision backdoor' - which is unexpected, given that thge apparent version is older than 5.4.5
Actually - or maybe not older, if the last number is an ascending numeric as opposed to a decimal fraction, if you understand what I mean.

Town said:

Transmit just means the file has been downloaded - you'd then need the 'System update successful' message to say the firmware was validated and has been applied.

Town said:

There are not any, for HTTP access.
In the 'backdoor' vulnerability, that request skips the authorisation check. Fixed in 5.4.5 and later firmware.

If SSH is enabled - it will dump you into the Hikvision 'psh' restricted shell, which provides no useful shell commands, and is protected with strong authentication.
But with serial console access, the bootloader should provide some access opportunities.
One of the easiest might be to alter the bootargs to include some combination of init=/bin/sh or single or debug=9
This varies with the specific version of bootloader.

If you can't find a version of firmware that would be accepted by the tftp updater (or maybe not blocked if it's running hacked firmware), then the serial console connection will be needed.

Town said:

Not for the DS-2CD3345-I - but I had a couple of DS-2CD3335-I that had been running the 'Dieter and Fiona' hacked firmware that had the update capabilities inhibited.
I fixed them up manually by using the serial console to boot the kernel only, then copying in the replacement application and rootfs files manually.

Sometimes its not clear, at least to me, if these models are G0 or G1 series.
Maybe try some G1 firmware to see if it takes.

Got it working putting the orignial digicap.dav with tftpd32.exe
booted into u-boot by ctrl+U
then issued command upf (update not working, it just uploads the original locked firmware)
with upf command new firmware loaded ok and settings resetted.
so i was able to set new password, but camera remains chinesed.

Well done for getting there.

If you want to see how the internals work, this may be worth trying :

Code:

setenv bootargs console=ttyAMA0,115200 debug single loglevel=8

to get to an ash prompt.

And attached is a bunch of language files to play with from a DS-2CD2335

Yes, the header only checked as part of the firmware validation.
Hiktools51 does not work with that newer version of firmware, the header information is not correct.

I am in the same psoition as you were with your cameras. I am unable to remember the passwords and atempting to flash a new FW results with the same problems you had.

I am tryin gto work out this (uboot) you mentioned off to help update the firmware rather then just send it to the cam.

Is Uboot a linux thing? or another app i can download and work with?

What is the model of camera?
What is the version of firmware as shown by SADP?
If it's 5.4.4 or earlier the password can be reset or extracted.

I will find out and let you know. The old nvr i have can still view the cameras as the password is saved on it. Is there a way to extract the password from the nvr? I want to upgrade the nvr to an 8 channel one, that's why i am in need of the passwords for the cameras.

P.s i also tried the nvr password on the camera as i know the nvr sometimes changes the password on the cameras when they are initialized.

The version according to SADP is v5.4.24 for 2 cameras and v5.4.52 for another 2 cameras.

The backdoor trick dosent work on any camera either

If you use the Hikvision tftp updater to apply the 5.4.4 or earlier firmware, the camera will be reset to an Inactive state.

Hi there, I have six DS-2CD3345-i cameras where the passwords were unknown, I have managed to reset four of them with assistance from HiK Support via the SADP "forgot password" key file function, but for two cameras I am unable to create the key file using SADP. Upon trying I get an error: "Failed to get the Key:Timeout" and "Failed to generate QR code". This did not happen to the others. The Support request simply advised to generate a key file using SADP, but since I am unable to they have not provided any further advice.

I have read several posts about various password issues, but so far can't find anything related to not being able to create the key file? Is there any suggestions on what could be causing this and how to solve it?

The camera's (and DVR) are Chinese versions (as the previous owner of the house who installed them was Chinese), but that in itself is not an issue for me. I am just wanting to reset the remaining cameras if possible. They are both running firmware v5.5.0_170728 (Chinese) and manufactured in Dec 2017.

Any suggestions or assistance I will be grateful.

I was able to reset the password after 2 weeks of googling, My firmware is 5.4.20 and it has this backdoor vulnerability. bp2008/HikPasswordHelper
