Lessons in IoT Hacking: How to Dead-Bug a BGA Flash Memory Chip

Dead-bugging — what is that, you ask? The concept comes from the idea that a memory chip, once it’s flipped over so you can attach wires to it, looks a little like a dead bug on its back. So why would we do this for the purposes of IoT hacking? The typical reason is if you want to extract the...

CVE-2021-27208

When booting a Zync-7000 SOC device from nand flash memory, the nand driver in the ROM does not validate the inputs when reading in any parameters in the nand’s parameter page. IF a field read in from the parameter page is too large, this causes a buffer overflow that could lead to arbitrary code...

Buffer overflow

When booting a Zync-7000 SOC device from nand flash memory, the nand driver in the ROM does not validate the inputs when reading in any parameters in the nand’s parameter page. IF a field read in from the parameter page is too large, this causes a buffer overflow that could lead to arbitrary code...

CVE-2021-27208

CVE-2021-27208 concerns a buffer overflow in the NAND parameter-page read path of the Xilinx Zynq-7000 ROM NAND driver when booting from NAND flash. The vulnerability arises because inputs from the NAND parameter page are not validated; if a field is too large, it can overflow a buffer and enable...

CVE-2021-27208: Buffer Copy without Checking Size of Input

When booting a Zync-7000 SOC device from nand flash memory, the nand driver in the ROM does not validate the inputs when reading in any parameters in the nand’s parameter page. IF a field read in from the parameter page is too large, this causes a buffer overflow that could lead to arbitrary code...

[SECURITY] Fedora 33 Update: f2fs-tools-1.14.0-1.fc33

NAND flash memory-based storage devices, such as SSD, and SD cards, have been widely being used for ranging from mobile to server systems. Since they are known to have different characteristics from the conventional rotational disks,a file system, an upper layer to the storage device, should adap...

CVE-2019-19815

A NULL pointer dereference flaw was found in F2FSPSB in fs/f2fs/f2fs.h in the F2FS filesystem exploiting the NAND flash memory-based storage device. This flaw allows an attacker to crash the system or leak internal kernel information. Mitigation Mitigation for this issue is either not available o...

How To Do Firmware Analysis. Tools, Tips, and Tricks

So, you’ve got a firmware dump. Perhaps a raw read off a chip? An update file you downloaded off the internet? Now what? Taking a firmware dump and turning it into something useful can sometimes be painful. Sometimes you’ll be faced with proprietary barely documented file formats, strange raw dat...

Bitdefender BOX 2 bootstrap update_setup command execution vulnerability

Summary An exploitable command execution vulnerability exists in the recovery partition of Bitdefender BOX 2, version 2.0.1.91. The API method /api/updatesetup does not perform firmware signature checks atomically, leading to an exploitable race condition TOCTTOU that allows arbitrary execution o...
