CVSS: 7.7EPSS: 0%CPEs: 5EXPL: 2CVE-2023-27480 – Data leak through a XAR import XXE attack in xwiki-platform-xar-model
https://notcve.org/view.php?id=CVE-2023-27480
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions any user with edit rights on a document can trigger an XAR import on a forged XAR file, leading to the ability to display the content of any file on the XWiki server host. This vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10-rc-1. Users are advised to upgrade. Users unable to upgrade may apply the patch `e3527b98fd` manually. • https://github.com/xwiki/xwiki-platform/commit/e3527b98fdd8dc8179c24dc55e662b2c55199434 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-gx4f-976g-7g6v https://jira.xwiki.org/browse/XWIKI-20320 • CWE-611: Improper Restriction of XML External Entity Reference •
CVSS: 9.9EPSS: 0%CPEs: 6EXPL: 2CVE-2023-27479 – Improper Neutralization of Directives in Dynamically Evaluated Code in org.xwiki.platform:xwiki-platform-panels-ui
https://notcve.org/view.php?id=CVE-2023-27479
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}}`. • https://github.com/xwiki/xwiki-platform/commit/6de5442f3c91c3634a66c7b458d5b142e1c2a2dc https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-qxjg-jhgw-qhrv https://jira.xwiki.org/browse/XWIKI-20294 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 5.4EPSS: 0%CPEs: 6EXPL: 2CVE-2023-26056 – XWiki Platform allows macro execution as any user without programming rights through the context macro
https://notcve.org/view.php?id=CVE-2023-26056
XWiki Platform is a generic wiki platform. Starting in version 3.0-milestone-1, it's possible to execute a script with the right of another user, provided the target user does not have programming right. The problem has been patched in XWiki 14.8-rc-1, 14.4.5, and 13.10.10. There are no known workarounds for this issue. • https://github.com/xwiki/xwiki-platform/commit/4b75f212c2dd2dfc5fb5726c7830c6dbc9a425c6 https://github.com/xwiki/xwiki-platform/commit/bd34ad6710ed72304304a3d5fec38b7cc050ef3b https://github.com/xwiki/xwiki-platform/commit/dd3f4735b41971b3afc3f3aedf6664b4e8be4894 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-859x-p6jp-rc2w https://jira.xwiki.org/browse/XWIKI-19856 • CWE-863: Incorrect Authorization •
CVSS: 9.9EPSS: 0%CPEs: 4EXPL: 1CVE-2023-26471 – XWiki Platform users may execute anything with superadmin right through comments and async macro
https://notcve.org/view.php?id=CVE-2023-26471
XWiki Platform is a generic wiki platform. Starting in version 11.6-rc-1, comments are supposed to be executed with the right of superadmin but in restricted mode (anything dangerous is disabled), but the async macro does not take into account the restricted mode. This means that any user with comment right can use the async macro to make it execute any wiki content with the right of superadmin. This has been patched in XWiki 14.9, 14.4.6, and 13.10.10. The only known workaround consists of applying a patch and rebuilding and redeploying `org.xwiki.platform:xwiki-platform-rendering-async-macro`. • https://github.com/xwiki/xwiki-platform/commit/00532d9f1404287cf3ec3a05056640d809516006 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-9cqm-5wf7-wcj7 https://jira.xwiki.org/browse/XWIKI-20234 • CWE-284: Improper Access Control •
CVSS: 9.9EPSS: 0%CPEs: 5EXPL: 2CVE-2023-26472 – XWiki Platform vulnerable to privilege escalation via async macro and IconThemeSheet from the user profile
https://notcve.org/view.php?id=CVE-2023-26472
XWiki Platform is a generic wiki platform. Starting in version 6.2-milestone-1, one can execute any wiki content with the right of IconThemeSheet author by creating an icon theme with certain content. This can be done by creating a new page or even through the user profile for users not having edit right. The issue has been patched in XWiki 14.9, 14.4.6, and 13.10.10. An available workaround is to fix the bug in the page `IconThemesCode.IconThemeSheet` by applying a modification from commit 48caf7491595238af2b531026a614221d5d61f38. • https://github.com/xwiki/xwiki-platform/commit/48caf7491595238af2b531026a614221d5d61f38#diff-2ec9d716673ee049937219cdb0a92e520f81da14ea84d144504b97ab2bdae243R45 https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vwr6-qp4q-2wj7 https://jira.xwiki.org/browse/XWIKI-19731 • CWE-116: Improper Encoding or Escaping of Output •
