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-2020-29238 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-2020-29238/ (Markdown: https://insights.sbomify.com/CVE-2020-29238/index.md)","id":"CVE-2020-29238","markdown":"https://insights.sbomify.com/CVE-2020-29238/index.md","name":"CVE-2020-29238","record":{"aliases":["GHSA-647h-v8f6-577g"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"ExpressVPN Router","requires_auth":"none","summary":"Remote attackers can obtain sensitive information from ExpressVPN Routers acting as reverse proxies via crafted requests exploiting an integer overflow.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"expressvpn","vendor":"expressvpn"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer buffer overflow in the Nginx webserver of ExpressVPN Router version 1 allows remote attackers to obtain sensitive information when the server running as reverse proxy via specially crafted request.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2021-04-13","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-04-13","kind":"exploitdb","ref":"49760","stars":null,"title":"ExpressVPN VPN Router 1.0 - Router Login Panel's Integer Overflow"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Integer overflow in n/a","id":"CVE-2020-29238","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-29239"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-29233"},"products":["n/a"],"published":"2021-03-10","related":[{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2024-25728","kev_date_added":null,"published":"2024-02-11"},{"cvss_score":7.1,"headline":"Path traversal in n/a","id":"CVE-2018-15490","kev_date_added":null,"published":"2019-01-02"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"Remote attackers can obtain sensitive information from ExpressVPN Routers acting as reverse proxies via crafted requests exploiting an integer overflow.","url":"https://insights.sbomify.com/CVE-2020-29238/"}
