CVSS: 4.6EPSS: 0%CPEs: 1EXPL: 0CVE-2017-3225 – Das U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector that may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data
https://notcve.org/view.php?id=CVE-2017-3225
24 Jul 2018 — Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. For devices utilizing this environment encryption mode, U-Boot's use of a zero initialization vector may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data. Das U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector. This allows an attacker to perform dictionary attacks on encrypted data produced by Das U-Boot to learn information about the... • http://www.securityfocus.com/bid/100675 • CWE-310: Cryptographic Issues CWE-329: Generation of Predictable IV with CBC Mode •
CVSS: 6.4EPSS: 0%CPEs: 1EXPL: 0CVE-2017-3226 – Das U-Boot's AES-CBC encryption feature improperly handles an error condition and may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data

24 Jul 2018 — Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. Devices that make use of Das U-Boot's AES-CBC encryption feature using environment encryption (i.e., setting the configuration parameter CONFIG_ENV_AES=y) read environment variables from disk as the encrypted disk image is processed. An attacker with physical access to the device can manipulate the encrypted environment data to include a crafted two-byte sequence which triggers an error in environment variable pars... • http://www.securityfocus.com/bid/100675 • CWE-310: Cryptographic Issues CWE-329: Generation of Predictable IV with CBC Mode •
