Severity ?
5.9 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N

Summary
eLabFTW is an open source electronic lab notebook manager for research teams. In versions of eLabFTW before 4.1.0, it allows attackers to bypass a brute-force protection mechanism by using many different forged PHPSESSID values in HTTP Cookie header. This issue has been addressed by implementing brute force login protection, as recommended by Owasp with Device Cookies. This mechanism will not impact users and will effectively thwart any brute-force attempts at guessing passwords. The only correct way to address this is to upgrade to version 4.1.0. Adding rate limitation upstream of the eLabFTW service is of course a valid option, with or without upgrading.

En las versiones de eLabFTW anteriores a 4.1.0, permite a atacantes omitir un mecanismo de protecci\u00f3n de fuerza bruta mediante el uso de varios valores falsos de PHPSESSID en el encabezado de la cookie HTTP. Este problema ha sido solucionado al implementar una protecci\u00f3n de inicio de sesi\u00f3n por fuerza bruta, tal y como recomienda Owasp con las Cookies de Dispositivo. Este mecanismo no afectar\u00e1 a usuarios y frustrar\u00e1 eficazmente cualquier intento de fuerza bruta para adivinar las contrase\u00f1as. La \u00fanica forma correcta de abordar esto es actualizar a la versi\u00f3n 4.1.0. A\u00f1adir la limitaci\u00f3n de la tasa del servicio eLabFTW es por supuesto una opci\u00f3n v\u00e1lida, con o sin actualizaci\u00f3n"
