In `org.xwiki.platform:xwiki-platform-web` versions 7.2-milestone-2 until 14.10.12 and `org.xwiki.platform:xwiki-platform-web-templates` prior to versions 14.10.12 and 15.5-rc-1, it is possible to pass a title to the page creation action that isn't displayed at first but then executed in the second step. This can be used by an attacker to trick a victim to execute code, allowing script execution if the victim has script right or remote code execution including full access to the XWiki instance if the victim has programming right.\n\nFor the attack to work, the attacker needs to convince the victim to visit a link like `<xwiki-host>/xwiki/bin/create/NonExistingSpace/WebHome?title=$services.logging.getLogger(%22foo%22).error(%22Script%20executed!%22)` where `<xwiki-host>` is the URL of the Wiki installation and to then click on the \"Create\" button on that page. The page looks like a regular XWiki page that the victim would also see when clicking the button to create a page that doesn't exist yet, the malicious code is not displayed anywhere on that page. After clicking the \"Create\" button, the malicious title would be displayed but at this point, the code has already been executed and the attacker could use this code also to hide the attack, e.g., by redirecting the victim again to the same page with an innocent title. It thus seems plausible that this attack could work if the attacker can place a fake \"create page\" button on a page which is possible with edit right.\n\nThis has been patched in `org.xwiki.platform:xwiki-platform-web` version 14.10.12 and `org.xwiki.platform:xwiki-platform-web-templates` versions 14.10.12 and 15.5-rc-1 by displaying the title already in the first step such that the victim can notice the attack before continuing. It is possible to manually patch the modified files from the patch in an existing installation. For the JavaScript change, the minified JavaScript file would need to be obtained from a build of XWiki and replaced accordingly."}, {"lang": "es", "value": "XWiki Platform es una plataforma wiki gen\u00e9rica que ofrece servicios de ejecuci\u00f3n para aplicaciones creadas sobre ella. En `org.xwiki.platform:xwiki-platform-web` versiones 7.2-milestone-2 hasta 14.10.12 y `org.xwiki.platform:xwiki-platform-web-templates` anteriores a las versiones 14.10.12 y 15.5-rc -1, es posible pasar un t\u00edtulo a la acci\u00f3n de creaci\u00f3n de p\u00e1gina que no se muestra al principio pero que luego se ejecuta en el segundo paso. Un atacante puede utilizar esto para enga\u00f1ar a una v\u00edctima para que ejecute c\u00f3digo, permitiendo la ejecuci\u00f3n de scripts si la v\u00edctima tiene derechos de ejecuci\u00f3n de scripts o de c\u00f3digo remoto, incluido el acceso completo a la instancia de XWiki si la v\u00edctima tiene derechos de programaci\u00f3n. Para que el ataque funcione, el atacante debe convencer a la v\u00edctima de que visite un enlace como `/xwiki/bin/create/NonExistingSpace/WebHome?title=$services.logging.getLogger(%22foo%22).error(%22Script%20executed!%22)` donde `` es la URL de la instalaci\u00f3n Wiki y luego haga clic en el bot\u00f3n \"Crear\" en esa p\u00e1gina. La p\u00e1gina parece una p\u00e1gina XWiki normal que la v\u00edctima tambi\u00e9n ver\u00eda al hacer clic en el bot\u00f3n para crear una p\u00e1gina que a\u00fan no existe; el c\u00f3digo malicioso no se muestra en ninguna parte de esa p\u00e1gina. Despu\u00e9s de hacer clic en el bot\u00f3n \"Crear\", se mostrar\u00e1 el t\u00edtulo malicioso, pero en este punto el c\u00f3digo ya se ha ejecutado y el atacante podr\u00eda utilizar este c\u00f3digo tambi\u00e9n para ocultar el ataque, por ejemplo, redirigiendo a la v\u00edctima nuevamente a la misma p\u00e1gina con Un t\u00edtulo inocente. Por lo tanto, parece plausible que este ataque pueda funcionar si el atacante puede colocar un bot\u00f3n falso de \"crear p\u00e1gina\" en una p\u00e1gina que sea posible con derecho de edici\u00f3n. Esto se ha parcheado en `org.xwiki.platform:xwiki-platform-web` versi\u00f3n 14.10.12 y `org.xwiki.platform:xwiki-platform-web-templates` versiones 14.10.12 y 15.5-rc-1 mostrando el t\u00edtulo ya en el primer paso para que la v\u00edctima pueda notar el ataque antes de continuar. Es posible parchear manualmente los archivos modificados desde el parche en una instalaci\u00f3n existente. Para el cambio de JavaScript, el archivo JavaScript minimizado deber\u00e1 obtenerse de una compilaci\u00f3n de XWiki y reemplazarse en consecuencia."}], "lastModified": "2023-11-02T18:06:56.367", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:xwiki:xwiki:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F42D13DD-5877-438F-9976-AC8DC0EA5ADA", "versionEndExcluding": "14.10.12", "versionStartIncluding": "7.3"}, {"criteria": "cpe:2.3:a:xwiki:xwiki:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CC654D33-71EE-4374-84CD-B964D1D135BA", "versionEndExcluding": "15.5", "versionStartIncluding": "15.0"}, {"criteria": "cpe:2.3:a:xwiki:xwiki:7.2:milestone2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C2A06C6F-1DBA-4E6D-901A-096F16C08D49"}, {"criteria": "cpe:2.3:a:xwiki:xwiki:7.2:milestone3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "470D146C-5EBF-4399-BF0C-26D9CC48DE0F"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
