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-2021-35242 in the wild and no public exploit code.\n\nAffected product: Solarwinds Serv-U. 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-2021-35242/ (Markdown: https://insights.sbomify.com/CVE-2021-35242/index.md)","id":"CVE-2021-35242","markdown":"https://insights.sbomify.com/CVE-2021-35242/index.md","name":"CVE-2021-35242","record":{"aliases":["GHSA-vrh8-5phj-x6h2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Serv-U FTP Server","requires_auth":"none","summary":"Serv-U server leaks valid CSRF tokens in responses to invalid requests, allowing attackers to bypass CSRF protections.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"SolarWinds","cpe":[{"product":"serv-u","vendor":"solarwinds"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Serv-U server responds with valid CSRFToken when the request contains only Session.","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":"A valid CSRF token is present in response to an invalid request","id":"CVE-2021-35242","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"solarwinds:serv-u","products":["solarwinds:serv-u"],"type":"csrf","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"HTTP PUT \u0026 DELETE Methods Enabled","id":"CVE-2021-35243"},"packages":[],"prev":{"headline":"Stored XSS via Help Server settings","id":"CVE-2021-35240"},"products":["Serv-U Server"],"published":"2021-12-06","related":[{"cvss_score":9,"headline":"SolarWinds Serv-U Remote Code Execution","id":"CVE-2021-35211","kev_date_added":"2021-11-03","published":"2021-07-14"},{"cvss_score":8.6,"headline":"SolarWinds Serv-U Path Traversal Vulnerability","id":"CVE-2024-28995","kev_date_added":"2024-07-17","published":"2024-06-06"},{"cvss_score":7.5,"headline":"SolarWinds Serv-U Uncontrolled Resource Consumption","id":"CVE-2026-28318","kev_date_added":"2026-06-05","published":"2026-06-04"},{"cvss_score":4.3,"headline":"SolarWinds Serv-U Improper Input Validation","id":"CVE-2021-35247","kev_date_added":"2022-01-21","published":"2022-01-07"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-35481","kev_date_added":null,"published":"2021-02-03"},{"cvss_score":9.1,"headline":"SolarWinds Serv-U Insecure Direct Object Reference (IDOR) Vulnerability","id":"CVE-2026-28302","kev_date_added":null,"published":"2026-07-21"},{"cvss_score":9.1,"headline":"SolarWinds Serv-U Remote Code Execution Vulnerability","id":"CVE-2026-28304","kev_date_added":null,"published":"2026-07-21"}],"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":["SolarWinds"]},"summary":"Serv-U server leaks valid CSRF tokens in responses to invalid requests, allowing attackers to bypass CSRF protections.","url":"https://insights.sbomify.com/CVE-2021-35242/"}
