FKIE_CVE-2026-25476

Vulnerability from fkie_nvd - Published: 2026-02-25 19:43 - Updated: 2026-02-28 00:42
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the session expiration check in `library/auth.inc.php` runs only when `skip_timeout_reset` is not present in the request. When `skip_timeout_reset=1` is sent, the entire block that calls `SessionTracker::isSessionExpired()` and forces logout on timeout is skipped. As a result, any request that includes this parameter (e.g. from auto-refresh pages like the Patient Flow Board) never runs the expiration check: expired sessions can continue to access data indefinitely, abandoned workstations stay active, and an attacker with a stolen session cookie can keep sending `skip_timeout_reset=1` to avoid being logged out. Version 8.0.0 fixes the issue.

Antes de la versi\u00f3n 8.0.0, la verificaci\u00f3n de expiraci\u00f3n de la sesi\u00f3n en `library/auth.inc.php` se ejecuta solo cuando `skip_timeout_reset` no est\u00e1 presente en la solicitud. Cuando se env\u00eda `skip_timeout_reset=1`, se omite todo el bloque que llama a `SessionTracker::isSessionExpired()` y fuerza el cierre de sesi\u00f3n por tiempo de espera. Como resultado, cualquier solicitud que incluya este par\u00e1metro (por ejemplo, de p\u00e1ginas de actualizaci\u00f3n autom\u00e1tica como el Panel de Flujo de Pacientes) nunca ejecuta la verificaci\u00f3n de expiraci\u00f3n: las sesiones expiradas pueden continuar accediendo a los datos indefinidamente, las estaciones de trabajo abandonadas permanecen activas, y un atacante con una cookie de sesi\u00f3n robada puede seguir enviando `skip_timeout_reset=1` para evitar ser desconectado. La versi\u00f3n 8.0.0 soluciona el problema."
