Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-5520 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.opencms:opencms-core (Maven): affected from 16.0; fixed in 17.0\n- org.opencms:opencms-core (Maven): affected from 16.0; fixed in 17.0\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-2024-5520/ (Markdown: https://insights.sbomify.com/CVE-2024-5520/index.md)","id":"CVE-2024-5520","markdown":"https://insights.sbomify.com/CVE-2024-5520/index.md","name":"CVE-2024-5520","record":{"aliases":["GHSA-vg6x-pchq-98mg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenCMS","requires_auth":"low_privilege","summary":"Privileged users can inject malicious JavaScript via the title field in OpenCMS, enabling cross-site scripting attacks.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCIBE","cpe":[{"product":"opencms","vendor":"alkacon"}],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/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":"Two Cross-Site Scripting vulnerabilities have been discovered in Alkacon's OpenCMS affecting version 16, which could allow a user with sufficient privileges to create and modify web pages through the admin panel, can execute malicious JavaScript code, after inserting code in the “title” field.","ecosystems":["Maven"],"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":"Cross-Site Scripting stored in Alkacon OpenCMS","id":"CVE-2024-5520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xss","year":"2024"},"n_packages":2,"n_references":1,"next":{"headline":"Cross-Site Scripting stored in Alkacon OpenCMS","id":"CVE-2024-5521"},"packages":[{"ecosystem":"Maven","fixed":["17.0"],"introduced":["16.0"],"last_affected":[],"package":"org.opencms:opencms-core","purl":null,"source":"GHSA-vg6x-pchq-98mg"},{"ecosystem":"Maven","fixed":["17.0"],"introduced":["16.0"],"last_affected":[],"package":"org.opencms:opencms-core","purl":"pkg:maven/org.opencms/opencms-core","source":"GHSA-vg6x-pchq-98mg"}],"prev":{"headline":"ItsourceCode Learning Management System Project In PHP login.php sql injection","id":"CVE-2024-5519"},"products":["OpenCMS"],"published":"2024-05-30","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-8811","kev_date_added":null,"published":"2018-03-20"},{"cvss_score":7.8,"headline":"Alkacon OpenCMS CSV Injection via New User module","id":"CVE-2019-11819","kev_date_added":null,"published":"2019-05-08"},{"cvss_score":6.8,"headline":"Cross-site scripting in n/a","id":"CVE-2005-4475","kev_date_added":null,"published":"2005-12-22"},{"cvss_score":6.5,"headline":"OpenCMS Cross-Site Scripting vulnerability","id":"CVE-2024-42699","kev_date_added":null,"published":"2025-04-21"},{"cvss_score":6.5,"headline":"XML External Entity Reference in org.opencms:opencms-core","id":"CVE-2021-3312","kev_date_added":null,"published":"2021-10-08"},{"cvss_score":6.5,"headline":"Alkacon OpenCMS Improper Access Control via system/workplace/views/admin/admin-main.jsp","id":"CVE-2006-3935","kev_date_added":null,"published":"2006-07-31"}],"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":"2024-08-01","vendors":["Alkacon"]},"summary":"Privileged users can inject malicious JavaScript via the title field in OpenCMS, enabling cross-site scripting attacks.","url":"https://insights.sbomify.com/CVE-2024-5520/"}
