The \"restricted\" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1, only escaped `<script>` and `<style>`-tags but neither attributes that can be used to inject scripts nor other dangerous HTML tags like `<iframe>`. As a consequence, any code relying on this \"restricted\" mode for security is vulnerable to JavaScript injection (\"cross-site scripting\"/XSS). When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. This problem has been patched in XWiki 14.6 RC1 with the introduction of a filter with allowed HTML elements and attributes that is enabled in restricted mode. There are no known workarounds apart from upgrading to a version including the fix.","state":"PUBLIC","assigner":"security-advisories@github.com","published_at":"2023-04-15 15:15:00","updated_at":"2023-04-25 18:26:00"},"problem_types":["CWE-79"],"metrics":[],"references":[{"url":"https://github.com/xwiki/xwiki-commons/commit/4a185e0594d90cd4916d60aa60bb4333dc5623b2","name":"https://github.com/xwiki/xwiki-commons/commit/4a185e0594d90cd4916d60aa60bb4333dc5623b2","refsource":"MISC","tags":[],"title":"XCOMMONS-2426: Provide a component for filtering safe HTML elements a… · xwiki/xwiki-commons@4a185e0 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://jira.xwiki.org/browse/XWIKI-9118","name":"https://jira.xwiki.org/browse/XWIKI-9118","refsource":"MISC","tags":[],"title":"Loading...","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://jira.xwiki.org/browse/XCOMMONS-1680","name":"https://jira.xwiki.org/browse/XCOMMONS-1680","refsource":"MISC","tags":[],"title":"[XCOMMONS-1680] Filter Html attributes in restricted mode based on a whitelist - XWiki.org JIRA","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://jira.xwiki.org/browse/XCOMMONS-2426","name":"https://jira.xwiki.org/browse/XCOMMONS-2426","refsource":"MISC","tags":[],"title":"Loading...","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-m3jr-cvhj-f35j","name":"https://github.com/xwiki/xwiki-commons/security/advisories/GHSA-m3jr-cvhj-f35j","refsource":"MISC","tags":[],"title":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in org.xwiki.commons:xwiki-commons-xml · Advisory · xwiki/xwiki-commons · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/xwiki/xwiki-commons/commit/b11eae9d82cb53f32962056b5faa73f3720c6182","name":"https://github.com/xwiki/xwiki-commons/commit/b11eae9d82cb53f32962056b5faa73f3720c6182","refsource":"MISC","tags":[],"title":"XCOMMONS-1680: Filter Html attributes in restricted mode based on a w… · xwiki/xwiki-commons@b11eae9 · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-29201","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29201","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"29201","vulnerable":"1","versionEndIncluding":"14.5","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"xwiki","cpe5":"xwiki","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"data_version":"4.0","data_type":"CVE","data_format":"MITRE","CVE_data_meta":{"ID":"CVE-2023-29201","ASSIGNER":"security-advisories@github.com","STATE":"PUBLIC"},"description":{"description_data":[{"lang":"eng","value":"XWiki Commons are technical libraries common to several other top level XWiki projects.
