An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-22840 exists.\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-2020-22840/ (Markdown: https://insights.sbomify.com/CVE-2020-22840/index.md)","id":"CVE-2020-22840","markdown":"https://insights.sbomify.com/CVE-2020-22840/index.md","name":"CVE-2020-22840","record":{"aliases":["GHSA-v56p-8m5q-738r"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"b2evolution CMS","requires_auth":"none","summary":"An attacker can redirect users to malicious sites via the redirect_to parameter in b2evolution CMS email passthrough script.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"b2evolution","vendor":"b2evolution"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Open redirect vulnerability in b2evolution CMS version prior to 6.11.6 allows an attacker to perform malicious open redirects to an attacker controlled resource via redirect_to parameter in email_passthrough.php.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-22840.yaml","stars":null,"title":"b2evolution CMS \u003c6.11.6 - Open Redirect"}],"tier":"weaponised"},"has_fix":false,"headline":"Open redirect in n/a","id":"CVE-2020-22840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-22841"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-22839"},"products":["n/a"],"published":"2021-02-09","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2016-8901","kev_date_added":null,"published":"2019-05-23"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2017-1000423","kev_date_added":null,"published":"2018-01-02"},{"cvss_score":9.1,"headline":"Auth bypass in n/a","id":"CVE-2022-30935","kev_date_added":null,"published":"2022-09-28"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2017-5539","kev_date_added":null,"published":"2017-01-23"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2021-28242","kev_date_added":null,"published":"2021-04-15"},{"cvss_score":8.1,"headline":"Path traversal in n/a","id":"CVE-2017-5480","kev_date_added":null,"published":"2017-01-15"},{"cvss_score":7.5,"headline":"Auth bypass in n/a","id":"CVE-2016-9479","kev_date_added":null,"published":"2016-12-02"}],"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":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"An attacker can redirect users to malicious sites via the redirect_to parameter in b2evolution CMS email passthrough script.","url":"https://insights.sbomify.com/CVE-2020-22840/"}
