An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-31718 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-2021-31718/ (Markdown: https://insights.sbomify.com/CVE-2021-31718/index.md)","id":"CVE-2021-31718","markdown":"https://insights.sbomify.com/CVE-2021-31718/index.md","name":"CVE-2021-31718","record":{"aliases":["GHSA-8jpp-c53f-gvrm"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"UPnP library","requires_auth":"none","summary":"An attacker can exploit DNS rebinding in the npupnp library's embedded web server to achieve remote code execution.","user_interaction":"required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"npupnp","vendor":"npupnp_project"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"The server in npupnp before 4.1.4 is affected by DNS rebinding in the embedded web server (including UPnP SOAP and GENA endpoints), leading to remote code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Server-side request forgery in n/a","id":"CVE-2021-31718","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-31721"},"packages":[],"prev":{"headline":"Cross-site Scripting in React Draft Wysiwyg","id":"CVE-2021-31712"},"products":["n/a"],"published":"2021-04-25","related":[],"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":"An attacker can exploit DNS rebinding in the npupnp library's embedded web server to achieve remote code execution.","url":"https://insights.sbomify.com/CVE-2021-31718/"}
