An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-50966 exists.\n\nAffected packages and fixed versions:\n- jose (Hex): affected all versions; fixed in 1.11.7\n- jose (Hex): affected all versions; fixed in 1.11.7\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-2023-50966/ (Markdown: https://insights.sbomify.com/CVE-2023-50966/index.md)","id":"CVE-2023-50966","markdown":"https://insights.sbomify.com/CVE-2023-50966/index.md","name":"CVE-2023-50966","record":{"aliases":["AZL-39719","AZL-39857","DEBIAN-CVE-2023-50966","GHSA-9mg4-v392-8j68","UBUNTU-CVE-2023-50966"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Erlang JOSE library","requires_auth":"none","summary":"Attackers can cause denial of service via high CPU consumption by sending a large PBES2 Count value in JOSE headers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"erlang-jose (aka JOSE for Erlang and Elixir) through 1.11.6 allow attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value in a JOSE header.","ecosystems":["Hex"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"erlang-jose vulnerable to denial of service via large p2c value","id":"CVE-2023-50966","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":2,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2023-50967"},"packages":[{"ecosystem":"Hex","fixed":["1.11.7"],"introduced":["0"],"last_affected":[],"package":"jose","purl":null,"source":"GHSA-9mg4-v392-8j68"},{"ecosystem":"Hex","fixed":["1.11.7"],"introduced":["0"],"last_affected":[],"package":"jose","purl":"pkg:hex/jose","source":"GHSA-9mg4-v392-8j68"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-50965"},"products":["n/a"],"published":"2024-03-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["n/a"]},"summary":"Attackers can cause denial of service via high CPU consumption by sending a large PBES2 Count value in JOSE headers.","url":"https://insights.sbomify.com/CVE-2023-50966/"}
