Dvbs-evb-kd1100hd-v1.1 !!install!!
DVBS-EVB-KD1100HD-V1.1 refers to a specific hardware board version commonly found in budget satellite receivers, often associated with brands like Star Track or generic 1506G/1506T chipset
From the naming convention, this appears to be an for a DVB-S (satellite) receiver or demodulator , likely based around a KD1100HD chipset (possibly from Montage Technology or a similar DVB-S2/S2X demodulator IC). dvbs-evb-kd1100hd-v1.1
One of the improvements often seen in the V1.1 revision over its predecessors is better shielding around the tuner circuit. In satellite reception, the signal-to-noise ratio is everything. The DVBS-EVB-KD1100HD-V1.1 utilizes improved capacitors and a refined ground plane to ensure that the high-frequency signals coming from the LNB are not degraded by the digital noise generated by the high-speed RAM and processor. This makes the board more stable in fringe reception areas where the satellite footprint is weak. Legacy and Modern Use DVBS-EVB-KD1100HD-V1
For Windows, this board would utilize BDA (Broadcast Driver Architecture) drivers. User applications like DVBViewer , SmartDVB , or ProgDVB (with generic device support) can usually interface with it, provided the kd1100hd.sys driver is installed. The DVBS-EVB-KD1100HD-V1

Nice write up – where can I get the vulnerable app? I checked IOLO’s website and the exploitdb but I can’t find 5.0.0.136
For “System Shield AntiVirus and AntiSpyware” you’ll need to run the downloader which downloads the main installation package but then you’ll need to also request a license. Best just to download “System Mechanic Pro” and install as a trial, this downloads the entire package and no license is required for installation

Hello.
Thanks for this demonstration!
I have a question. With this exploit, can we access to the winlogon.exe and open a handle for read and write memory?
Kind regards,
Yes you can as “SeDebugPrivilege” is also enabled
Why doesn’t it work with csrss.exe?
pHandle = OpenProcess(PROCESS_VM_READ, 0, 428); //my csrss PID
printf(“> pHandle: %d || %s\n”, pHandle, pHandle);
i got: 0 || (null)
It should work, most likely haven’t got the necessary privilege
Oh yes, thanks. But can you help me with “SeDebugPrivilege”. What offset?
Kind regards,
The SeDebugPrivilege is already enabled in this exploit, what you can do it use a previous exploit of mine which uses shellcode being injected in the winlogon process.
Thanks for nice write up. I want to study this case, so I’ve downloaded the link

And opened amp.sys file with IDA pro, but I could not find the code related to ctl code 0x00226003. How can I find it?
Best just do a text search for 226003 and only one entry will be listed
Thanks! I found with its hex byte ’03 60 22′ in IDA search and reached vulnerable function.
