An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-29001 in the wild and no public exploit code.\n\nAffected product: contiki-ng. 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-2023-29001/ (Markdown: https://insights.sbomify.com/CVE-2023-29001/index.md)","id":"CVE-2023-29001","markdown":"https://insights.sbomify.com/CVE-2023-29001/index.md","name":"CVE-2023-29001","record":{"aliases":["GHSA-7p75-mf53-ffwm"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IoT operating system","requires_auth":"none","summary":"Attackers can cause a stack overflow and denial of service in Contiki-NG IoT devices by sending crafted IPv6 packets with invalid source routing headers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"contiki-ng","vendor":"contiki-ng"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"Contiki-NG is an open-source, cross-platform operating system for IoT devices. The Contiki-NG operating system processes source routing headers (SRH) in its two alternative RPL protocol implementations. The IPv6 implementation uses the results of this processing to determine whether an incoming packet should be forwarded to another host. Because of missing validation of the resulting next-hop address, an uncontrolled recursion may occur in the tcpip_ipv6_output function in the os/net/ipv6/tcpip.c module when receiving a packet with a next-hop address that is a local address. Attackers that have the possibility to send IPv6 packets to the Contiki-NG host can therefore trigger deeply nested recursive calls, which can cause a stack overflow. The vulnerability has not been patched in the current release of Contiki-NG, but is expected to be patched in the next release. The problem can be fixed by applying the patch in Contiki-NG pull request #2264. Users are advised to either apply the patch manually or to wait for the next release. There are no known workarounds for this vulnerability.","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":"Uncontrolled recursion due to insufficient validation of the IPv6 source routing header in Contiki-NG","id":"CVE-2023-29001","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Debug mode leaks confidential data in Cilium","id":"CVE-2023-29002"},"packages":[],"prev":{"headline":"Nextcloud Desktop client does not verify received singed certificate in end-to-end encryption","id":"CVE-2023-29000"},"products":["contiki-ng"],"published":"2024-11-27","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2018-19417","kev_date_added":null,"published":"2018-11-21"},{"cvss_score":9.8,"headline":"Contiki-NG has off-by-one error in Antelope DBMS","id":"CVE-2023-30546","kev_date_added":null,"published":"2023-04-26"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-24336","kev_date_added":null,"published":"2020-12-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14934","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14935","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14936","kev_date_added":null,"published":"2020-08-18"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-8359","kev_date_added":null,"published":"2020-04-23"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-27","vendors":["contiki-ng"]},"summary":"Attackers can cause a stack overflow and denial of service in Contiki-NG IoT devices by sending crafted IPv6 packets with invalid source routing headers.","url":"https://insights.sbomify.com/CVE-2023-29001/"}
