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-2023-46960 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pypxe (PyPI): affected all versions up to 1.8.4; no fix listed\n- pypxe (PyPI): affected all versions up to 1.8.4; no fix listed\n- PyPXE (PyPI): affected all versions up to 1.8.4; no fix listed\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-2023-46960/ (Markdown: https://insights.sbomify.com/CVE-2023-46960/index.md)","id":"CVE-2023-46960","markdown":"https://insights.sbomify.com/CVE-2023-46960/index.md","name":"CVE-2023-46960","record":{"aliases":["GHSA-82wx-rxf8-fxch","PYSEC-2026-1838"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PXE boot server","requires_auth":"none","summary":"A remote attacker can cause a denial of service in PyPXE via a buffer overflow in the TFTP module.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Overflow vulnerability in PyPXE v.1.8.4 allows a remote attacker to cause a denial of service via the handle function in the tftp module.","ecosystems":["PyPI"],"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":"PyPXE Buffer Overflow vulnerability","id":"CVE-2023-46960","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":3,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2023-46963"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["1.8.4"],"package":"PyPXE","purl":null,"source":"GHSA-82wx-rxf8-fxch"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["1.8.4"],"package":"pypxe","purl":"pkg:pypi/pypxe","source":"GHSA-82wx-rxf8-fxch"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["1.8.4"],"package":"pypxe","purl":"pkg:pypi/pypxe","source":"PYSEC-2026-1838"}],"prev":{"headline":"Code injection in n/a","id":"CVE-2023-46958"},"products":["n/a"],"published":"2024-04-29","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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"2024-08-02","vendors":["n/a"]},"summary":"A remote attacker can cause a denial of service in PyPXE via a buffer overflow in the TFTP module.","url":"https://insights.sbomify.com/CVE-2023-46960/"}
