Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-20028 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- contao/contao (Packagist): affected from 3.0.0; fixed in 3.5.37\n- contao/contao (Packagist): affected from 3.0.0; fixed in 3.5.37\n- contao/contao (Packagist): affected from 4.4.0; fixed in 4.4.31\n- contao/contao (Packagist): affected from 4.4.0; fixed in 4.4.31\n- contao/contao (Packagist): affected from 4.6.0; fixed in 4.6.11\n- contao/contao (Packagist): affected from 4.6.0; fixed in 4.6.11\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-2018-20028/ (Markdown: https://insights.sbomify.com/CVE-2018-20028/index.md)","id":"CVE-2018-20028","markdown":"https://insights.sbomify.com/CVE-2018-20028/index.md","name":"CVE-2018-20028","record":{"aliases":["GHSA-q99w-j4mj-7hj8"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Contao CMS","requires_auth":"low_privilege","summary":"Attackers can bypass access controls in Contao CMS to perform unauthorized actions due to incorrect access control implementation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"contao_cms","vendor":"contao"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[],"description":"Contao 3.x before 3.5.37, 4.4.x before 4.4.31 and 4.6.x before 4.6.11 has Incorrect Access Control.","ecosystems":["Packagist"],"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":"Contao Information Disclosure via Access Control Flaws","id":"CVE-2018-20028","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"missing_authorization","year":"2018"},"n_packages":6,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2018-20029"},"packages":[{"ecosystem":"Packagist","fixed":["3.5.37"],"introduced":["3.0.0"],"last_affected":[],"package":"contao/contao","purl":null,"source":"GHSA-q99w-j4mj-7hj8"},{"ecosystem":"Packagist","fixed":["3.5.37"],"introduced":["3.0.0"],"last_affected":[],"package":"contao/contao","purl":"pkg:composer/contao/contao","source":"GHSA-q99w-j4mj-7hj8"},{"ecosystem":"Packagist","fixed":["4.4.31"],"introduced":["4.4.0"],"last_affected":[],"package":"contao/contao","purl":null,"source":"GHSA-q99w-j4mj-7hj8"},{"ecosystem":"Packagist","fixed":["4.4.31"],"introduced":["4.4.0"],"last_affected":[],"package":"contao/contao","purl":"pkg:composer/contao/contao","source":"GHSA-q99w-j4mj-7hj8"},{"ecosystem":"Packagist","fixed":["4.6.11"],"introduced":["4.6.0"],"last_affected":[],"package":"contao/contao","purl":null,"source":"GHSA-q99w-j4mj-7hj8"},{"ecosystem":"Packagist","fixed":["4.6.11"],"introduced":["4.6.0"],"last_affected":[],"package":"contao/contao","purl":"pkg:composer/contao/contao","source":"GHSA-q99w-j4mj-7hj8"}],"prev":{"headline":"Code injection in n/a","id":"CVE-2018-20027"},"products":["n/a"],"published":"2019-04-17","related":[{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2014-1860","kev_date_added":null,"published":"2020-01-08"},{"cvss_score":9.8,"headline":"Contao SQL injection in the backend and listing module","id":"CVE-2017-16558","kev_date_added":null,"published":"2019-04-25"},{"cvss_score":9.8,"headline":"Contao Does Not Invalidate Existing Sessions When Password Changes","id":"CVE-2019-10641","kev_date_added":null,"published":"2019-04-17"},{"cvss_score":9.8,"headline":"Contao Does Not Expire Tokens Correctly","id":"CVE-2019-10643","kev_date_added":null,"published":"2019-04-17"},{"cvss_score":8.8,"headline":"Contao CSRF Token Bypass","id":"CVE-2019-10642","kev_date_added":null,"published":"2019-04-17"},{"cvss_score":8.8,"headline":"Contao Core directory traversal vulnerability","id":"CVE-2017-10993","kev_date_added":null,"published":"2017-07-21"},{"cvss_score":6.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2012-1297","kev_date_added":null,"published":"2012-03-19"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can bypass access controls in Contao CMS to perform unauthorized actions due to incorrect access control implementation.","url":"https://insights.sbomify.com/CVE-2018-20028/"}
