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-2020-5402 in the wild and no public exploit code.\n\nAffected product: Cloud Foundry UAA. 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-2020-5402/ (Markdown: https://insights.sbomify.com/CVE-2020-5402/index.md)","id":"CVE-2020-5402","markdown":"https://insights.sbomify.com/CVE-2020-5402/index.md","name":"CVE-2020-5402","record":{"aliases":["GHSA-5fqw-8f7q-58m9"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Cloud Foundry UAA","requires_auth":"none","summary":"Attackers can exploit missing state parameter checks in Cloud Foundry UAA to perform CSRF attacks against users authenticating with external identity providers.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"pivotal","cpe":[{"product":"cf-deployment","vendor":"cloudfoundry"},{"product":"user_account_and_authentication","vendor":"cloudfoundry"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"In Cloud Foundry UAA, versions prior to 74.14.0, a CSRF vulnerability exists due to the OAuth2 state parameter not being checked in the callback function when authenticating with external identity providers.","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":"UAA fails to check the state parameter when authenticating with external IDPs","id":"CVE-2020-5402","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"DoS Via Malformed URL with Reactor Netty HTTP Server","id":"CVE-2020-5403"},"packages":[],"prev":{"headline":"Cloud Foundry GoRouter is vulnerable to cache poisoning","id":"CVE-2020-5401"},"products":["UAA"],"published":"2020-02-27","related":[{"cvss_score":9.1,"headline":"Auth bypass in Cloud Foundry Diego and CF Deployment","id":"CVE-2022-31733","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":8.8,"headline":"UAA logs all query parameters with debug logging level","id":"CVE-2019-11293","kev_date_added":null,"published":"2019-12-06"},{"cvss_score":8.8,"headline":"Cloud Foundry UAA logs query parameters in tomcat access file","id":"CVE-2019-11290","kev_date_added":null,"published":"2019-11-25"},{"cvss_score":8.8,"headline":"Password leak in smbdriver logs","id":"CVE-2019-11283","kev_date_added":null,"published":"2019-10-23"},{"cvss_score":8.8,"headline":"Information disclosure in Garden-runC","id":"CVE-2018-1191","kev_date_added":null,"published":"2018-03-29"},{"cvss_score":8.7,"headline":"Java Projects using HTTP to fetch dependencies","id":"CVE-2019-3801","kev_date_added":null,"published":"2019-04-25"}],"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":"2024-09-16","vendors":["Cloud Foundry"]},"summary":"Attackers can exploit missing state parameter checks in Cloud Foundry UAA to perform CSRF attacks against users authenticating with external identity providers.","url":"https://insights.sbomify.com/CVE-2020-5402/"}
