CVE-2017-3226
6.4 · MEDIUMOverview
CVE-2017-3226 is a medium-severity vulnerability affecting denx u-boot. It was published on July 24, 2018 and has a CVSS 3.0 base score of 6.4 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 6.4, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
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 parsing. This error condition is improperly handled by Das U-Boot, resulting in an immediate process termination with a debugging message.
Remediation
Check the references section for vendor advisories and patches from denx. Update u-boot to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
