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-2021-28302 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-2021-28302/ (Markdown: https://insights.sbomify.com/CVE-2021-28302/index.md)","id":"CVE-2021-28302","markdown":"https://insights.sbomify.com/CVE-2021-28302/index.md","name":"CVE-2021-28302","record":{"aliases":["DEBIAN-CVE-2021-28302","GHSA-24m8-vm8v-rrfv","UBUNTU-CVE-2021-28302"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"pupnp library","requires_auth":"none","summary":"A stack overflow in the pupnp library allows attackers to cause a denial of service via recursive node freeing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pupnp","vendor":"pupnp_project"}],"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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A stack overflow in pupnp before version 1.14.5 can cause the denial of service through the Parser_parseDocument() function. ixmlNode_free() will release a child node recursively, which will consume stack space and lead to a crash.","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":"Denial of service in n/a","id":"CVE-2021-28302","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Fix a use-after-free bug in diesels Sqlite backend","id":"CVE-2021-28305"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2021-28300"},"products":["n/a"],"published":"2021-03-12","related":[{"cvss_score":7.6,"headline":"DNS rebinding in pupnp","id":"CVE-2021-29462","kev_date_added":null,"published":"2021-04-20"},{"cvss_score":7.5,"headline":"pupnp: NULL pointer dereference in ixmlNode_compare crashes on non-namespaced attributes","id":"CVE-2026-57486","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":7.5,"headline":"libupnp chunked HTTP bodies can bypass g_maxContentLength and be fully buffered","id":"CVE-2026-57487","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":7.5,"headline":"pupnp: Denial of service via blocking DNS resolution in parse_uri()/GENA callback parsing","id":"CVE-2026-77630","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":7.1,"headline":"pupnp: Integer truncation in HTTP Content-Length parsing enables request smuggling","id":"CVE-2026-57488","kev_date_added":null,"published":"2026-10-16"},{"cvss_score":6.5,"headline":"pupnp: Incomplete fix for CVE-2021-28302: recursive DOM functions cause stack overflow","id":"CVE-2026-55862","kev_date_added":null,"published":"2026-10-16"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"A stack overflow in the pupnp library allows attackers to cause a denial of service via recursive node freeing.","url":"https://insights.sbomify.com/CVE-2021-28302/"}
