FKIE_CVE-2017-12424
Vulnerability from fkie_nvd - Published: 2017-08-04 09:29 - Updated: 2025-04-20 01:37
Severity ?
Summary
In shadow before 4.5, the newusers tool could be made to manipulate internal data structures in ways unintended by the authors. Malformed input may lead to crashes (with a buffer overflow or other memory corruption) or other unspecified behaviors. This crosses a privilege boundary in, for example, certain web-hosting environments in which a Control Panel allows an unprivileged user account to create subaccounts.

"value": "En las versiones de Shadow anteriores a la 4.5, la herramienta newusers podr\u00eda utilizarse para manipular estructuras de datos internas de formas no permitidas por los desarrolladores. Las entradas manipuladas podr\u00edan llevar a ca\u00eddas (con un desbordamiento de b\u00fafer u otros tipos de corrupci\u00f3n de memoria) o a otro tipo de comportamiento sin especificar. Esto provoca un l\u00edmite de privilegios en, por ejemplo, ciertos entornos de hospedaje web en los que un Panel de Control permite que una cuenta de usuario sin privilegios cree subcuentas."
