An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-5478 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- contao/core (Packagist): affected from 3.0.0; fixed in 3.5.32\n- contao/core (Packagist): affected from 3.0.0; fixed in 3.5.32\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-2018-5478/ (Markdown: https://insights.sbomify.com/CVE-2018-5478/index.md)","id":"CVE-2018-5478","markdown":"https://insights.sbomify.com/CVE-2018-5478/index.md","name":"CVE-2018-5478","record":{"aliases":["GHSA-mpg7-2rx9-h5qp"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Contao CMS","requires_auth":"none","summary":"Cross-site scripting in Contao's frontend newsletter unsubscribe module allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"contao","vendor":"contao"}],"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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Contao 3.x before 3.5.32 allows XSS via the unsubscribe module in the frontend newsletter extension.","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 Cross-site Scripting vulnerabililty","id":"CVE-2018-5478","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2018"},"n_packages":2,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-5479"},"packages":[{"ecosystem":"Packagist","fixed":["3.5.32"],"introduced":["3.0.0"],"last_affected":[],"package":"contao/core","purl":null,"source":"GHSA-mpg7-2rx9-h5qp"},{"ecosystem":"Packagist","fixed":["3.5.32"],"introduced":["3.0.0"],"last_affected":[],"package":"contao/core","purl":"pkg:composer/contao/core","source":"GHSA-mpg7-2rx9-h5qp"}],"prev":{"headline":"Information disclosure in ABB netCADOPS Web Application","id":"CVE-2018-5477"},"products":["n/a"],"published":"2023-09-21","related":[{"cvss_score":9.8,"headline":"Remote Code Execution in Contao Managed Edition","id":"CVE-2022-26265","kev_date_added":null,"published":"2022-03-18"},{"cvss_score":9.8,"headline":"Contao SQL injection in the file manager","id":"CVE-2019-11512","kev_date_added":null,"published":"2019-07-09"},{"cvss_score":8.8,"headline":"Contao core SQL Injection Vulnerability","id":"CVE-2012-4383","kev_date_added":null,"published":"2020-01-29"},{"cvss_score":8.8,"headline":"Unrestricted file uploads in Contao","id":"CVE-2019-19745","kev_date_added":null,"published":"2019-12-17"},{"cvss_score":8.4,"headline":"Contao possible cookie sharing with external domains while checking protected pages for broken links","id":"CVE-2024-28235","kev_date_added":null,"published":"2024-04-09"},{"cvss_score":8.3,"headline":"Remote command execution through file upload in contao/core-bundle","id":"CVE-2024-45398","kev_date_added":null,"published":"2024-09-17"},{"cvss_score":8,"headline":"Privilege escalation via form generator","id":"CVE-2021-37627","kev_date_added":null,"published":"2021-08-11"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-24","vendors":["n/a"]},"summary":"Cross-site scripting in Contao's frontend newsletter unsubscribe module allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2018-5478/"}
