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-2013-1856 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- activesupport (RubyGems): affected from 3.0.0; fixed in 3.1.12\n- activesupport (RubyGems): affected from 3.0.0; fixed in 3.1.12\n- activesupport (RubyGems): affected from 3.2.0; fixed in 3.2.13\n- activesupport (RubyGems): affected from 3.2.0; fixed in 3.2.13\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-2013-1856/ (Markdown: https://insights.sbomify.com/CVE-2013-1856/index.md)","id":"CVE-2013-1856","markdown":"https://insights.sbomify.com/CVE-2013-1856/index.md","name":"CVE-2013-1856","record":{"aliases":["GHSA-9c2j-593q-3g82"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Ruby on Rails","requires_auth":"none","summary":"Remote attackers can read arbitrary files or cause denial of service via XML external entity attacks in Ruby on Rails when using JRuby.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"rails","vendor":"rubyonrails"},{"product":"ruby_on_rails","vendor":"rubyonrails"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The ActiveSupport::XmlMini_JDOM backend in lib/active_support/xml_mini/jdom.rb in the Active Support component in Ruby on Rails 3.0.x and 3.1.x before 3.1.12 and 3.2.x before 3.2.13, when JRuby is used, does not properly restrict the capabilities of the XML parser, which allows remote attackers to read arbitrary files or cause a denial of service (resource consumption) via vectors involving (1) an external DTD or (2) an external entity declaration in conjunction with an entity reference.","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":"activesupport Improper Input Validation vulnerability","id":"CVE-2013-1856","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"rubyonrails:rails","products":["rubyonrails:rails"],"type":"xxe","year":"2013"},"n_packages":4,"n_references":5,"next":{"headline":"actionpack Cross-site Scripting vulnerability","id":"CVE-2013-1857"},"packages":[{"ecosystem":"RubyGems","fixed":["3.1.12"],"introduced":["3.0.0"],"last_affected":[],"package":"activesupport","purl":null,"source":"GHSA-9c2j-593q-3g82"},{"ecosystem":"RubyGems","fixed":["3.1.12"],"introduced":["3.0.0"],"last_affected":[],"package":"activesupport","purl":"pkg:gem/activesupport","source":"GHSA-9c2j-593q-3g82"},{"ecosystem":"RubyGems","fixed":["3.2.13"],"introduced":["3.2.0"],"last_affected":[],"package":"activesupport","purl":null,"source":"GHSA-9c2j-593q-3g82"},{"ecosystem":"RubyGems","fixed":["3.2.13"],"introduced":["3.2.0"],"last_affected":[],"package":"activesupport","purl":"pkg:gem/activesupport","source":"GHSA-9c2j-593q-3g82"}],"prev":{"headline":"actionpack Cross-site Scripting vulnerability","id":"CVE-2013-1855"},"products":["n/a"],"published":"2013-03-19","related":[{"cvss_score":10,"headline":"Active Record contains deserialization of arbitrary YAML","id":"CVE-2013-0277","kev_date_added":null,"published":"2013-02-13"},{"cvss_score":8.1,"headline":"SQL injection in n/a","id":"CVE-2017-17916","kev_date_added":null,"published":"2017-12-29"},{"cvss_score":8.1,"headline":"SQL injection in n/a","id":"CVE-2017-17917","kev_date_added":null,"published":"2017-12-29"},{"cvss_score":8,"headline":"Rails Active Storage has possible Path Traversal in DiskService","id":"CVE-2026-33195","kev_date_added":null,"published":"2026-03-23"},{"cvss_score":7.5,"headline":"Rails possible ReDoS vulnerability in Accept header parsing in Action Dispatch","id":"CVE-2024-26142","kev_date_added":null,"published":"2024-02-27"},{"cvss_score":7.5,"headline":"ReDoS based DoS vulnerability in Action Dispatch","id":"CVE-2023-22792","kev_date_added":null,"published":"2023-02-09"},{"cvss_score":7.5,"headline":"Denial of Service in Action Dispatch","id":"CVE-2021-22902","kev_date_added":null,"published":"2021-06-11"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can read arbitrary files or cause denial of service via XML external entity attacks in Ruby on Rails when using JRuby.","url":"https://insights.sbomify.com/CVE-2013-1856/"}
