An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-42343 exists.\n\nAffected packages and fixed versions:\n- org.opencms:opencms-core (Maven): affected all versions; fixed in 16.0\n- org.opencms:opencms-core (Maven): affected all versions; fixed in 16.0\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-2023-42343/ (Markdown: https://insights.sbomify.com/CVE-2023-42343/index.md)","id":"CVE-2023-42343","markdown":"https://insights.sbomify.com/CVE-2023-42343/index.md","name":"CVE-2023-42343","record":{"aliases":["GHSA-8gpv-c454-3hfc"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenCms CMS","requires_auth":"none","summary":"Attackers can inject malicious scripts into OpenCms via the cmis-online/type parameter, potentially compromising user sessions or executing code.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","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":"A Cross Site Scripting vulnerability in Alkacon OpenCms before 10.5.1 exists via cmis-online/type.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2023/CVE-2023-42343.yaml","stars":null,"title":"OpenCMS - Cross-Site Scripting"}],"tier":"weaponised"},"has_fix":true,"headline":"Alkacon OpenCms is vulnerable to XSS via cmis-online/type","id":"CVE-2023-42343","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2023"},"n_packages":2,"n_references":1,"next":{"headline":"Alkacon OpenCms allows remote unauthenticated attackers to obtain sensitive information","id":"CVE-2023-42344"},"packages":[{"ecosystem":"Maven","fixed":["16.0"],"introduced":["0"],"last_affected":[],"package":"org.opencms:opencms-core","purl":null,"source":"GHSA-8gpv-c454-3hfc"},{"ecosystem":"Maven","fixed":["16.0"],"introduced":["0"],"last_affected":[],"package":"org.opencms:opencms-core","purl":"pkg:maven/org.opencms/opencms-core","source":"GHSA-8gpv-c454-3hfc"}],"prev":{"headline":"Hardcoded credentials in n/a","id":"CVE-2023-42336"},"products":["n/a"],"published":"2026-05-08","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-08","vendors":["n/a"]},"summary":"Attackers can inject malicious scripts into OpenCms via the cmis-online/type parameter, potentially compromising user sessions or executing code.","url":"https://insights.sbomify.com/CVE-2023-42343/"}
