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-2020-8202 in the wild and no public exploit code.\n\nAffected product: Nextcloud Preferred Providers. 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-2020-8202/ (Markdown: https://insights.sbomify.com/CVE-2020-8202/index.md)","id":"CVE-2020-8202","markdown":"https://insights.sbomify.com/CVE-2020-8202/index.md","name":"CVE-2020-8202","record":{"aliases":["GHSA-5qmp-36gw-8g5g"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Preferred Providers","requires_auth":"none","summary":"An attacker can cause a denial of service in Nextcloud Preferred Providers by submitting a very long password due to improper input checks.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"preferred_providers","vendor":"nextcloud"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","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-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"Improper check of inputs in Nextcloud Preferred Providers app v1.6.0 allowed to perform a denial of service attack when using a very long password.","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 Nextcloud Preferred Providers","id":"CVE-2020-8202","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Prototype Pollution in lodash","id":"CVE-2020-8203"},"packages":[],"prev":{"headline":"Other in Node","id":"CVE-2020-8201"},"products":["Nextcloud Preferred Providers"],"published":"2020-07-30","related":[{"cvss_score":5.3,"headline":"Business logic in Nextcloud Preferred Provider","id":"CVE-2020-8228","kev_date_added":null,"published":"2020-10-05"}],"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":"An attacker can cause a denial of service in Nextcloud Preferred Providers by submitting a very long password due to improper input checks.","url":"https://insights.sbomify.com/CVE-2020-8202/"}
