It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-3226 in the wild and no public exploit code.\n\nAffected product: Das U-Boot. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2017-3226/ (Markdown: https://insights.sbomify.com/CVE-2017-3226/index.md)","id":"CVE-2017-3226","markdown":"https://insights.sbomify.com/CVE-2017-3226/index.md","name":"CVE-2017-3226","record":{"aliases":["DEBIAN-CVE-2017-3226","GHSA-wg74-j96c-c2wj","UBUNTU-CVE-2017-3226"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"U-Boot bootloader","requires_auth":"none","summary":"An attacker with physical access can exploit improper error handling in U-Boot's AES-CBC implementation to decrypt data or cause denial of service.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"u-boot","vendor":"denx"}],"cvss":{"score":6.4,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-310","name":null},{"id":"CWE-329","name":"Generation of Predictable IV with CBC Mode"}],"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Weak cryptography in U-Boot","id":"CVE-2017-3226","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2017"},"n_packages":0,"n_references":2,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2017-3228"},"packages":[],"prev":{"headline":"Weak cryptography in U-Boot","id":"CVE-2017-3225"},"products":["U-Boot"],"published":"2018-07-24","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2022-34835","kev_date_added":null,"published":"2022-06-29"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-30767","kev_date_added":null,"published":"2022-05-16"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-8432","kev_date_added":null,"published":"2020-01-29"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-14192","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14193","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14194","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14195","kev_date_added":null,"published":"2019-07-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Das"]},"summary":"An attacker with physical access can exploit improper error handling in U-Boot's AES-CBC implementation to decrypt data or cause denial of service.","url":"https://insights.sbomify.com/CVE-2017-3226/"}
