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-2020-13898 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-13898/ (Markdown: https://insights.sbomify.com/CVE-2020-13898/index.md)","id":"CVE-2020-13898","markdown":"https://insights.sbomify.com/CVE-2020-13898/index.md","name":"CVE-2020-13898","record":{"aliases":["DEBIAN-CVE-2020-13898","GHSA-35h6-3hm3-w4f8","UBUNTU-CVE-2020-13898"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Janus WebRTC Server","requires_auth":"none","summary":"A NULL pointer dereference in Janus WebRTC Server allows attackers to cause a denial of service via crafted SDP messages.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"janus","vendor":"meetecho"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"An issue was discovered in janus-gateway (aka Janus WebRTC Server) through 0.10.0. janus_sdp_process in sdp.c has a NULL pointer dereference.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2020-13898","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-13899"},"packages":[],"prev":{"headline":"HESK before 3.1.10 allows reflected XSS.","id":"CVE-2020-13897"},"products":["n/a"],"published":"2020-06-10","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14033","kev_date_added":null,"published":"2020-06-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-14034","kev_date_added":null,"published":"2020-06-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-13901","kev_date_added":null,"published":"2020-06-10"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2020-10574","kev_date_added":null,"published":"2020-03-14"},{"cvss_score":8.8,"headline":"Cross-site Scripting (XSS) - Stored in meetecho/janus-gateway","id":"CVE-2021-4020","kev_date_added":null,"published":"2021-11-27"},{"cvss_score":8.1,"headline":"Cross-site Scripting (XSS) - Stored in meetecho/janus-gateway","id":"CVE-2021-4124","kev_date_added":null,"published":"2021-12-16"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A NULL pointer dereference in Janus WebRTC Server allows attackers to cause a denial of service via crafted SDP messages.","url":"https://insights.sbomify.com/CVE-2020-13898/"}
