{"id":"CVE-2023-29525","summary":"Privilege escalation from view right on XWiki.Notifications.Code.LegacyNotificationAdministration in xwiki-platform","details":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Affected versions of xwiki are subject to code injection in the `since` parameter of the `/xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration` endpoint. This provides an XWiki syntax injection attack via the since-parameter, allowing privilege escalation from view to programming rights and subsequent code execution privilege. The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8 and 14.10.3. Users are advised to upgrade. Users unable to upgrade may modify the page `XWiki.Notifications.Code.LegacyNotificationAdministration` to add the missing escaping. For versions \u003c 14.6-rc-1 a workaround is to modify the file `\u003cxwikiwebapp\u003e/templates/distribution/eventmigration.wiki` to add the missing escaping.","aliases":["GHSA-jgg7-w2rj-58cj"],"modified":"2026-08-12T03:51:34.282733607Z","published":"2023-04-18T23:01:46.239Z","database_specific":{"cwe_ids":["CWE-74"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/29xxx/CVE-2023-29525.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-20287"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/29xxx/CVE-2023-29525.json"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-jgg7-w2rj-58cj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-29525"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/8e7c7f90f2ddaf067cb5b83b181af41513028754#diff-4e13f4ee4a42938bf1201b7ee71ca32edeacba22559daf0bcb89d534e0225949R70"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/xwiki/xwiki-commons","events":[{"introduced":"0"},{"fixed":"48ee3193230753aecf8a86d7c8ff3e8f869e8330"},{"introduced":"bae1e23e73cafc007e5f28b39a04bfa0acf0199c"},{"fixed":"011dee864805aec0b24151f69f230a42e40087da"}],"database_specific":{"source":"CPE_RANGE","cpe":"cpe:2.3:a:xwiki:xwiki:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"14.4.8"},{"introduced":"14.5"},{"fixed":"14.10.3"}]}},{"type":"GIT","repo":"https://github.com/xwiki/xwiki-platform","events":[{"introduced":"0"},{"fixed":"b469b950e7fe3d22f00b639d43f286bf871472b1"},{"introduced":"ab4dfeaeef13360eebcaa507bc652073aa89a427"},{"fixed":"a5bb704d3517251bc86e46ea0370ba800adb6a4e"},{"fixed":"6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766"},{"fixed":"8e7c7f90f2ddaf067cb5b83b181af41513028754"}],"database_specific":{"cpe":"cpe:2.3:a:xwiki:xwiki:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"14.4.8"},{"introduced":"14.5"},{"fixed":"14.10.3"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["xwiki-commons-14.10.2","xwiki-commons-14.10.1","xwiki-commons-14.10","xwiki-commons-14.4.7","xwiki-commons-14.4.6","xwiki-commons-14.4.5","xwiki-commons-14.4.4","xwiki-commons-14.4.3","xwiki-commons-14.4.2","xwiki-commons-14.4.1","xwiki-commons-14.4","xwiki-commons-14.4-rc-1","xwiki-commons-8.3-milestone-2","xwiki-commons-8.3-milestone-1","xwiki-commons-8.2-milestone-2","xwiki-commons-8.2-milestone-1","xwiki-commons-8.1-milestone-2","xwiki-commons-8.1-milestone-1","xwiki-commons-8.0-milestone-2","xwiki-commons-8.0-milestone-1","xwiki-platform-14.10.2","xwiki-platform-14.10.1","xwiki-platform-14.10","xwiki-platform-14.4.7","xwiki-platform-14.4.6","xwiki-platform-14.4.5","xwiki-platform-14.4.4","xwiki-platform-14.4.3","xwiki-platform-14.4.2","xwiki-platform-14.4.1","xwiki-platform-14.4","xwiki-platform-14.4-rc-1","xwiki-platform-9.9-rc-2","xwiki-platform-8.3-milestone-1","xwiki-platform-8.2-milestone-2","xwiki-platform-8.2-milestone-1","xwiki-platform-8.1-milestone-2","xwiki-platform-8.1-milestone-1","xwiki-platform-8.0-milestone-2","xwiki-platform-8.0-milestone-1","xwiki-platform-7.4-milestone-2","xwiki-platform-7.4-milestone-1","xwiki-platform-7.3-milestone-2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-29525.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
