Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-40176 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 4.1-milestone-2; fixed in 14.10.5\n- org.xwiki.platform:xwiki-platform-web-templates (Maven): affected from 4.1-milestone-2; fixed in 14.10.5\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-2023-40176/ (Markdown: https://insights.sbomify.com/CVE-2023-40176/index.md)","id":"CVE-2023-40176","markdown":"https://insights.sbomify.com/CVE-2023-40176/index.md","name":"CVE-2023-40176","record":{"aliases":["GHSA-h8cm-3v5f-rgp6"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts via user timezone preferences, leading to data theft and privilege escalation for other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Any registered user can exploit a stored XSS through their user profile by setting the payload as the value of the time zone user preference. Even though the time zone is selected from a drop down (no free text value) it can still be set from JavaScript (using the browser developer tools) or by calling the save URL on the user profile with the right query string. Once the time zone is set it is displayed without escaping which means the payload gets executed for any user that visits the malicious user profile, allowing the attacker to steal information and even gain more access rights (escalation to programming rights). This issue is present since version 4.1M2 when the time zone user preference was introduced. The issue has been fixed in XWiki 14.10.5 and 15.1RC1.","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":"SXSS in the user profile via the timezone displayer","id":"CVE-2023-40176","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"xss","year":"2023"},"n_packages":2,"n_references":3,"next":{"headline":"XWiki Platform privilege escalation (PR) from account through AWM content fields","id":"CVE-2023-40177"},"packages":[{"ecosystem":"Maven","fixed":["14.10.5"],"introduced":["4.1-milestone-2"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-web-templates","purl":null,"source":"GHSA-h8cm-3v5f-rgp6"},{"ecosystem":"Maven","fixed":["14.10.5"],"introduced":["4.1-milestone-2"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-web-templates","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-web-templates","source":"GHSA-h8cm-3v5f-rgp6"}],"prev":{"headline":"Inconsistent Interpretation of HTTP Requests in puma","id":"CVE-2023-40175"},"products":["xwiki-platform"],"published":"2023-08-23","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":"2024-10-02","vendors":["xwiki"]},"summary":"Attackers can inject malicious scripts via user timezone preferences, leading to data theft and privilege escalation for other users.","url":"https://insights.sbomify.com/CVE-2023-40176/"}
