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-2022-0878 in the wild and no public exploit code.\n\nAffected product: Combined Charging System. 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-2022-0878/ (Markdown: https://insights.sbomify.com/CVE-2022-0878/index.md)","id":"CVE-2022-0878","markdown":"https://insights.sbomify.com/CVE-2022-0878/index.md","name":"CVE-2022-0878","record":{"aliases":["GHSA-qw95-rrxc-r294"],"analysis":{"component_type":"ics_ot","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"EV charging system","requires_auth":"none","summary":"Attackers can remotely disrupt electric vehicle charging sessions via electromagnetic interference, affecting all compliant CCS implementations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[{"product":"combined_charging_system_firmware","vendor":"combined_charging_system_project"}],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Electric Vehicle (EV) commonly utilises the Combined Charging System (CCS) for DC rapid charging. To exchange important messages such as the State of Charge (SoC) with the Electric Vehicle Supply Equipment (EVSE) CCS uses a high-bandwidth IP link provided by the HomePlug Green PHY (HPGP) power-line communication (PLC) technology. The attack interrupts necessary control communication between the vehicle and charger, causing charging sessions to abort. The attack can be conducted wirelessly from a distance using electromagnetic interference, allowing individual vehicles or entire fleets to be disrupted simultaneously. In addition, the attack can be mounted with off-the-shelf radio hardware and minimal technical knowledge. With a power budget of 1 W, the attack is successful from around 47 m distance. The exploited behavior is a required part of the HomePlug Green PHY, DIN 70121 \u0026 ISO 15118 standards and all known implementations exhibit it. In addition to electric cars, Brokenwire affects electric ships, airplanes and heavy duty vehicles utilising these standards.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Novel attack against the Combined Charging System (CCS) in electric vehicles to remotely cause a denial of service","id":"CVE-2022-0878","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Caldera Forms \u003c 1.9.7 - Reflected Cross-Site Scripting","id":"CVE-2022-0879"},"packages":[],"prev":{"headline":"Cross-site Scripting (XSS) - Stored in bookstackapp/bookstack","id":"CVE-2022-0877"},"products":["Combined Charging System","HomePlug GreenPHY"],"published":"2022-04-12","related":[],"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":"2024-09-16","vendors":["Combined Charging System"]},"summary":"Attackers can remotely disrupt electric vehicle charging sessions via electromagnetic interference, affecting all compliant CCS implementations.","url":"https://insights.sbomify.com/CVE-2022-0878/"}
