VAR-201807-0269

Vulnerability from variot - Updated: 2023-12-18 12:01

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 encrypted data. Das U-Boot of AES-CBC Multiple vulnerabilities exist in cryptographic implementations. Information leakage due to differences in processing time (CWE-208) - CVE-2017-3226 Das U-Boot of AES-CBC The encryption process is deficient in the process when reading the encrypted environment variable. As a result, an attacker could decrypt the content on your device or possibly tamper with it.An attacker with access to the device may be able to decrypt the content on the device
