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-2023-28731 in the wild and no public exploit code.\n\nAffected product: AcyMailing Newsletter Plugin for Joomla in the Enterprise version. 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-2023-28731/ (Markdown: https://insights.sbomify.com/CVE-2023-28731/index.md)","id":"CVE-2023-28731","markdown":"https://insights.sbomify.com/CVE-2023-28731/index.md","name":"CVE-2023-28731","record":{"aliases":["GHSA-2qgx-8w4f-jc5v"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Joomla newsletter plugin","requires_auth":"none","summary":"Unauthenticated attackers can achieve remote code execution via unrestricted file upload if campaign creation is enabled on the front-office.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[{"product":"acymailing","vendor":"acymailing"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"AnyMailing Joomla Plugin is vulnerable to unauthenticated remote code execution, when being granted access to the campaign's creation on front-office due to unrestricted file upload allowing PHP code to be injected. \n\nThis issue affects AnyMailing Joomla Plugin Enterprise in versions below 8.3.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Unauthenticated RCE affecting the AcyMailing plugin for Joomla","id":"CVE-2023-28731","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Missing access control affecting the AcyMailing plugin for Joomla","id":"CVE-2023-28732"},"packages":[],"prev":{"headline":"Memory corruption in Control FPWIN Pro","id":"CVE-2023-28730"},"products":["Newsletter Plugin for Joomla in the Enterprise version"],"published":"2023-03-30","related":[{"cvss_score":9.5,"headline":"File upload in AcyMailing Enterprise extension for Joomla","id":"CVE-2026-94132","kev_date_added":null,"published":"2026-09-26"},{"cvss_score":9.2,"headline":"Joomla Extension - acymailing.com - SQL Injection in AcyMailing extension \u003c 10.11.1","id":"CVE-2026-56292","kev_date_added":null,"published":"2026-07-09"},{"cvss_score":8.3,"headline":"Joomla Extension - acymailing.com - Unauthenticated arbitrary file deletion in AcyMailing Enterprise extension \u003c 11.1.0","id":"CVE-2026-94131","kev_date_added":null,"published":"2026-09-26"},{"cvss_score":7.5,"headline":"AcyMailing \u003c= 9.7.2 - Authenticated (Subscriber+) Arbitrary File Upload via acym_extractArchive Function","id":"CVE-2024-7384","kev_date_added":null,"published":"2024-08-22"},{"cvss_score":7.2,"headline":"Stored XSS affecting the AcyMailing plugin for Joomla","id":"CVE-2023-28733","kev_date_added":null,"published":"2023-03-30"},{"cvss_score":7.1,"headline":"WordPress AcyMailing SMTP Newsletter Plugin \u003c= 8.6.2 is vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-41867","kev_date_added":null,"published":"2023-09-25"}],"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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-11","vendors":["AcyMailing"]},"summary":"Unauthenticated attackers can achieve remote code execution via unrestricted file upload if campaign creation is enabled on the front-office.","url":"https://insights.sbomify.com/CVE-2023-28731/"}
