Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-27479 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-panels-ui (Maven): affected from 14.0; fixed in 14.4.7\n- org.xwiki.platform:xwiki-platform-panels-ui (Maven): affected from 14.0; fixed in 14.4.7\n- org.xwiki.platform:xwiki-platform-panels-ui (Maven): affected from 14.5; fixed in 14.10-rc-1\n- org.xwiki.platform:xwiki-platform-panels-ui (Maven): affected from 14.5; fixed in 14.10-rc-1\n- org.xwiki.platform:xwiki-platform-panels-ui (Maven): affected from 6.3-milestone-2; fixed in 13.10.11\n- org.xwiki.platform:xwiki-platform-panels-ui (Maven): affected from 6.3-milestone-2; fixed in 13.10.11\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-2023-27479/ (Markdown: https://insights.sbomify.com/CVE-2023-27479/index.md)","id":"CVE-2023-27479","markdown":"https://insights.sbomify.com/CVE-2023-27479/index.md","name":"CVE-2023-27479","record":{"aliases":["GHSA-qxjg-jhgw-qhrv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki platform","requires_auth":"low_privilege","summary":"Authenticated users with view rights can execute arbitrary code via improper escaping in UIX parameters, leading to full system access.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with view rights can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of UIX parameters. A proof of concept exploit is to log in, add an `XWiki.UIExtensionClass` xobject to the user profile page, with an Extension Parameters content containing `label={{/html}} {{async async=\"true\" cached=\"false\" context=\"doc.reference\"}}{{groovy}}println(\"Hello \" + \"from groovy!\"){{/groovy}}{{/async}}`. Then, navigating to `PanelsCode.ApplicationsPanelConfigurationSheet` (i.e., `\u003cxwiki-host\u003e/xwiki/bin/view/PanelsCode/ApplicationsPanelConfigurationSheet` where `\u003cxwiki-host\u003e` is the URL of your XWiki installation) should not execute the Groovy script. If it does, you will see `Hello from groovy!` displayed on the screen. This vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1. Users are advised to upgrade. For users unable to upgrade the issue can be fixed by editing the `PanelsCode.ApplicationsPanelConfigurationSheet` wiki page and making the same modifications  as shown in commit `6de5442f3c`.","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":"Improper Neutralization of Directives in Dynamically Evaluated Code in org.xwiki.platform:xwiki-platform-panels-ui","id":"CVE-2023-27479","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"code_injection","year":"2023"},"n_packages":6,"n_references":3,"next":{"headline":"Data leak through a XAR import XXE attack in xwiki-platform-xar-model","id":"CVE-2023-27480"},"packages":[{"ecosystem":"Maven","fixed":["14.4.7"],"introduced":["14.0"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-panels-ui","purl":null,"source":"GHSA-qxjg-jhgw-qhrv"},{"ecosystem":"Maven","fixed":["14.4.7"],"introduced":["14.0"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-panels-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-panels-ui","source":"GHSA-qxjg-jhgw-qhrv"},{"ecosystem":"Maven","fixed":["14.10-rc-1"],"introduced":["14.5"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-panels-ui","purl":null,"source":"GHSA-qxjg-jhgw-qhrv"},{"ecosystem":"Maven","fixed":["14.10-rc-1"],"introduced":["14.5"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-panels-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-panels-ui","source":"GHSA-qxjg-jhgw-qhrv"},{"ecosystem":"Maven","fixed":["13.10.11"],"introduced":["6.3-milestone-2"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-panels-ui","purl":null,"source":"GHSA-qxjg-jhgw-qhrv"},{"ecosystem":"Maven","fixed":["13.10.11"],"introduced":["6.3-milestone-2"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-panels-ui","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-panels-ui","source":"GHSA-qxjg-jhgw-qhrv"}],"prev":{"headline":"Disclosure of unrelated data in libmemcached-awesome","id":"CVE-2023-27478"},"products":["xwiki-platform"],"published":"2023-03-07","related":[{"cvss_score":9.8,"headline":"XWiki Platform Eval Injection","id":"CVE-2025-24893","kev_date_added":"2025-10-30","published":"2025-02-20"},{"cvss_score":10,"headline":"XWiki Rendering is vulnerable to RCE attacks when processing nested macros","id":"CVE-2025-53836","kev_date_added":null,"published":"2025-07-14"},{"cvss_score":10,"headline":"XWiki allows remote code execution through the extension sheet","id":"CVE-2024-55662","kev_date_added":null,"published":"2024-12-12"},{"cvss_score":10,"headline":"XWiki allows remote code execution from account through macro descriptions and XWiki.XWikiSyntaxMacrosList","id":"CVE-2024-55877","kev_date_added":null,"published":"2024-12-12"},{"cvss_score":10,"headline":"XWiki Platform vulnerable to remote code execution from account via SearchSuggestConfigSheet","id":"CVE-2024-37901","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":10,"headline":"XWiki programming rights may be inherited by inclusion","id":"CVE-2024-38369","kev_date_added":null,"published":"2024-06-24"},{"cvss_score":10,"headline":"XWiki Platform: Remote code execution from account via SearchSuggestSourceSheet","id":"CVE-2024-31465","kev_date_added":null,"published":"2024-04-10"}],"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":"total"},"state":"PUBLISHED","updated":"2025-02-25","vendors":["xwiki"]},"summary":"Authenticated users with view rights can execute arbitrary code via improper escaping in UIX parameters, leading to full system access.","url":"https://insights.sbomify.com/CVE-2023-27479/"}
