CVE-2026-23734

Estado: AplazadaCrítica (9.3)—

XWiki Platform is a generic wiki platform. Versions prior to 18.1.0-rc-1, 17.10.3, 17.4.9, and 16.10.17 allow access to read configuration files by using URLs such as http://localhost:8080/bin/ssx/Main/WebHome?resource=/../../WEB-INF/xwiki.cfg&minify=false, leading to Path Traversal. The vulnerability is can be exploited via resources parameter the ssx and jsx endpoints by using leading slashes. This issue has been patched in 18.1.0-rc-1, 17.10.3, 17.4.9, 16.10.17.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Path traversal en endpoint web público (ssx/jsx) sin autenticación (PR:N) ni interacción (UI:N) permite lectura de archivos de configuración (VC:H). AV:N, PR:N → T1190; impacto acceso a datos locales (CWE-23, WEB-INF/xwiki.cfg).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
