{"id":"CVE-2022-41935","aliases":["GHSA-p2x4-6ghr-6vmq"],"url":"https://o3.security/vulnerability/CVE-2022-41935","summary":"Exposure of Sensitive Information to an Unauthorized Actor in org.xwiki.platform:xwiki-platform-livetable-ui","details":"### Impact\n\nUser without the right to view documents can deduce their existence by repeated Livetable queries.\n\n#### Reproduction steps\n\n1. Restrict \"view\" access to `Sandbox.TestPage3` by setting an explicit view right for admins\n1. As a user who is not an admin, open `<server>/bin/get/XWiki/LiveTableResults?outputSyntax=plain&classname=&collist=doc.title%2Cdoc.location%2Cdoc.content&doc.title=Sandbo&doc.location=Sandbox.TestPage3&doc.content=dummy&limit=0` where `<server>` is the URL of your XWiki installation.\n\n#### Expect Result:\n\nNo results are displayed as the user doesn't have view rights on Sandbox.TestPage3.\n\n##### Actual Result:\n\nThe result\n\n```json\n{\n  \"reqNo\": null,\n  \"matchingtags\": {},\n  \"tags\": [],\n  \"totalrows\": 1,\n  \"returnedrows\": 0,\n  \"offset\": 1,\n  \"rows\": [\n    {\n      \"doc_viewable\": false,\n      \"doc_fullName\": \"obfuscated\"\n    }\n  ]\n}\n```\n\nis displayed.\n\nThis reveals that a document `Sandbox.TestPage3` exists (we explicitly searched for this name) which has a title containing `\"Sandbo\"` and a content containing `\"dummy\"`. By starting with a single letter and then iteratively extending the match, the full content of the title/content or XObject properties can be discovered. Several tests can be combined in a single request to use binary search to narrow down the actual match from a list of possible characters/words. If the used alphabet is known and smaller than 128 distinct characters, it is possible to discover one character with 7 requests. Alternatively, frequencies of words and word pairs (2-gram frequencies) can be used to first guess whole words and only resort to guessing individual characters if none of the predicted words match, allowing a much faster recovery of the textual content. As it also depends on the content how easy the attack is and how much recovered content would be a \"successful\" attack, it is hard to quantify how many requests are necessary.\n\n### Patches\n\nThe issue has been patched in XWiki 14.6RC1, 13.10.8, and 14.4.3, the response is not properly cleaned up of obfuscated entries.\n\n### Workarounds\n\nThe [patch](https://github.com/xwiki/xwiki-platform/commit/1450b6e3c69ac7df25e5a2571186d1f43402facd#diff-5a739e5865b1f1ad9d79b724791be51b0095a0170cc078911c940478b13b949a) for the document `XWiki.LiveTableResultsMacros` can be manually applied or a XAR archive of a patched version can be [imported](https://www.xwiki.org/xwiki/bin/view/Documentation/UserGuide/Features/Imports#HImportingXWikipages), on versions >= 12.10.11, >= 13.9-rc-1, and >= 13.4.4.\n\n### References\n\n- https://github.com/xwiki/xwiki-platform/commit/1450b6e3c69ac7df25e5a2571186d1f43402facd#diff-5a739e5865b1f1ad9d79b724791be51b0095a0170cc078911c940478b13b949a\n- https://jira.xwiki.org/browse/XWIKI-19999\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n- Open an issue in [Jira XWiki.org](https://jira.xwiki.org/)\n- Email us at [Security Mailing List](mailto:security@xwiki.org)\n","published":"2022-11-23T00:00:00Z","modified":"2026-08-12T13:33:28.661404Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":2,"affectedPackages":[{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-livetable-ui","fixedVersion":"13.10.8"},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-livetable-ui","fixedVersion":"14.4.3"},{"ecosystem":"Maven","name":"org.xwiki.platform:xwiki-platform-livetable-ui","fixedVersion":"14.6-rc-1"}],"fix":{"url":"https://github.com/xwiki/xwiki-platform/commit/1450b6e3c69ac7df25e5a2571186d1f43402facd#diff-5a739e5865b1f1ad9d79b724791be51b0095a0170cc078911c940478b13b949a","label":"xwiki/xwiki-platform@1450b6e"},"references":[{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-19999"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/41xxx/CVE-2022-41935.json"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-p2x4-6ghr-6vmq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-41935"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/1450b6e3c69ac7df25e5a2571186d1f43402facd#diff-5a739e5865b1f1ad9d79b724791be51b0095a0170cc078911c940478b13b949a"},{"type":"PACKAGE","url":"https://github.com/xwiki/xwiki-platform"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T13:33:28.661404Z"}}
