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-2021-43805 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- solidus_core (RubyGems): affected all versions; fixed in 2.11.13\n- solidus_core (RubyGems): affected all versions; fixed in 2.11.13\n- solidus_core (RubyGems): affected from 3.0.0; fixed in 3.0.4\n- solidus_core (RubyGems): affected from 3.0.0; fixed in 3.0.4\n- solidus_core (RubyGems): affected from 3.1.0; fixed in 3.1.4\n- solidus_core (RubyGems): affected from 3.1.0; fixed in 3.1.4\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-2021-43805/ (Markdown: https://insights.sbomify.com/CVE-2021-43805/index.md)","id":"CVE-2021-43805","markdown":"https://insights.sbomify.com/CVE-2021-43805/index.md","name":"CVE-2021-43805","record":{"aliases":["GHSA-qxmr-qxh6-2cc9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Solidus ecommerce platform","requires_auth":"none","summary":"Attackers can cause denial of service in Solidus guest checkout via exponential backtracking in email validation regex.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"solidus","vendor":"nebulab"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"Solidus is a free, open-source ecommerce platform built on Rails. Versions of Solidus prior to 3.1.4, 3.0.4, and 2.11.13 have a denial of service vulnerability that could be exploited during a guest checkout. The regular expression used to validate a guest order's email was subject to exponential backtracking through a fragment like `a.a.` Versions 3.1.4, 3.0.4, and 2.11.13 have been patched to use a different regular expression. The maintainers added a check for email addresses that are no longer valid that will print information about any affected orders that exist. If a prompt upgrade is not an option, a workaround is available. It is possible to edit the file `config/application.rb` manually (with code provided by the maintainers in the GitHub Security Advisory) to check email validity.","ecosystems":["RubyGems"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"ReDos vulnerability on guest checkout email validation","id":"CVE-2021-43805","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":6,"n_references":2,"next":{"headline":"SQL injection in Tuleap","id":"CVE-2021-43806"},"packages":[{"ecosystem":"RubyGems","fixed":["2.11.13"],"introduced":["0"],"last_affected":[],"package":"solidus_core","purl":null,"source":"GHSA-qxmr-qxh6-2cc9"},{"ecosystem":"RubyGems","fixed":["2.11.13"],"introduced":["0"],"last_affected":[],"package":"solidus_core","purl":"pkg:gem/solidus_core","source":"GHSA-qxmr-qxh6-2cc9"},{"ecosystem":"RubyGems","fixed":["3.0.4"],"introduced":["3.0.0"],"last_affected":[],"package":"solidus_core","purl":null,"source":"GHSA-qxmr-qxh6-2cc9"},{"ecosystem":"RubyGems","fixed":["3.0.4"],"introduced":["3.0.0"],"last_affected":[],"package":"solidus_core","purl":"pkg:gem/solidus_core","source":"GHSA-qxmr-qxh6-2cc9"},{"ecosystem":"RubyGems","fixed":["3.1.4"],"introduced":["3.1.0"],"last_affected":[],"package":"solidus_core","purl":null,"source":"GHSA-qxmr-qxh6-2cc9"},{"ecosystem":"RubyGems","fixed":["3.1.4"],"introduced":["3.1.0"],"last_affected":[],"package":"solidus_core","purl":"pkg:gem/solidus_core","source":"GHSA-qxmr-qxh6-2cc9"}],"prev":{"headline":"Out-of-bounds read when parsing RTCP BYE message in PJSIP","id":"CVE-2021-43804"},"products":["solidus"],"published":"2021-12-07","related":[{"cvss_score":5.3,"headline":"CSRF forgery protection bypass for Spree::OrdersController#populate","id":"CVE-2021-43846","kev_date_added":null,"published":"2021-12-20"},{"cvss_score":5.3,"headline":"Ability to change order address without triggering address validations in solidus","id":"CVE-2020-15109","kev_date_added":null,"published":"2020-08-04"},{"cvss_score":2.3,"headline":"CSRF allows attacker to finalize/unfinalize order adjustments in solidus_backend","id":"CVE-2022-31000","kev_date_added":null,"published":"2022-06-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":["solidusio"]},"summary":"Attackers can cause denial of service in Solidus guest checkout via exponential backtracking in email validation regex.","url":"https://insights.sbomify.com/CVE-2021-43805/"}
