CVE-2026-59680

Estado: Pendiente de análisisAlta (8.6)—

An OS command injection vulnerability was found in yast2-users. When displaying the "Password Settings" tab of a user, get_password_term() in src/include/users/dialogs.rb read the shadowLastChange and shadowExpire fields with GetString(), which performs no numeric validation, and passed the resulting string to format_days_after_epoch(). That helper interpolated the value into a shell command executed via Ruby backticks without quoting or escaping.

Impact: an administrator who manages users against an external/federated LDAP directory via `yast2 users` triggers root command execution the moment they view or edit that particular user's "Password Settings" tab. No "join domain" or trust setup is required, just browsing/editing one user entry.

ExplotaciónT1203 Exploitation for Client Executionexecution85 %
Impacto principalT1059 Command and Scripting Interpreterexecution90 %

Vector CVSS con UI:R (interacción del usuario requerida: view/edit Password Settings) y acceso remoto sobre aplicación local (AV:N, PR:L). La inyección de comandos OS sin escape en backticks Ruby permite ejecución de código arbitrario como root al administrador que visualiza campos LDAP manipulados.
