FKIE_CVE-2026-25889

Vulnerability from fkie_nvd - Published: 2026-02-09 22:16 - Updated: 2026-02-23 17:55
Severity ?
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
Summary
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to 2.57.1, a case-sensitivity flaw in the password validation logic allows any authenticated user to change their password (or an admin to change any user's password) without providing the current password. By using Title Case field name "Password" instead of lowercase "password" in the API request, the current_password verification is completely bypassed. This enables account takeover if an attacker obtains a valid JWT token through XSS, session hijacking, or other means. This vulnerability is fixed in 2.57.1.

Anterior a la 2.57.1, una falla de sensibilidad a may\u00fasculas y min\u00fasculas en la l\u00f3gica de validaci\u00f3n de contrase\u00f1as permite a cualquier usuario autenticado cambiar su contrase\u00f1a (o a un administrador cambiar la contrase\u00f1a de cualquier usuario) sin proporcionar la contrase\u00f1a actual. Al usar el nombre de campo en formato \u0027Title Case\u0027 \u0027Password\u0027 en lugar de \u0027password\u0027 en min\u00fasculas en la solicitud de la API, la verificaci\u00f3n de current_password es completamente eludida. Esto permite la toma de control de cuenta si un atacante obtiene un token JWT v\u00e1lido a trav\u00e9s de XSS, secuestro de sesi\u00f3n, u otros medios. Esta vulnerabilidad est\u00e1 corregida en la 2.57.1."
