Vulnerability from fkie_nvd - Published: 2026-03-30 00:16 - Updated: 2026-03-30 13:26
Severity
2.1 (Low) - CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N
Summary
Hardcoded Password Vulnerability have been found in CENTUM. Affected products contain a hardcoded password for the user account (PROG) used for CENTUM Authentication Mode within the system. Under the following conditions, there is a risk that an attacker could log in as the PROG user. The default permission for the PROG users is S1 permission (equivalent to OFFUSER). Therefore, for properly permission-controlled targets of operation and monitoring, even if an attacker user in as the PROG user, the risk of critical operations or configuration changes being performed is considered low. (If the PROG user's permissions have been changed for any reason, there is a risk that operations or configuration changes may be performed under the modified permissions. The CVSS values below are for the default permissions.) Additionally, exploiting this vulnerability requires an attacker to already have access to the HIS screen controls. Therefore, an attacker can already operate and monitor at that point, regardless of this vulnerability. The conditions under which this vulnerability is exploited: If all of the following conditions are met, the affected products are vulnerable to this vulnerability. -An attacker obtains the hardcoded password using a certain method. -The HIS with the affected product installed is configured in CTM authentication mode. -An attacker must have direct access to the aforementioned HIS or be able to break into it remotely using a certain method and perform screen operations. The affected products and versions are as follows: CENTUM VP R5.01.00 to R5.04.20, R6.01.00 to R6.12.00 and R7.01.00.

      "value": "Se ha encontrado una Vulnerabilidad de Contrase\u00f1a Hardcodeada en CENTUM. Los productos afectados contienen una contrase\u00f1a hardcodeada para la cuenta de usuario (PROG) utilizada para el Modo de Autenticaci\u00f3n de CENTUM dentro del sistema. Bajo las siguientes condiciones, existe un riesgo de que un atacante pueda iniciar sesi\u00f3n como el usuario PROG.\n\nEl permiso predeterminado para los usuarios PROG es el permiso S1 (equivalente a OFFUSER). Por lo tanto, para objetivos de operaci\u00f3n y monitoreo con permisos controlados adecuadamente, incluso si un atacante inicia sesi\u00f3n como el usuario PROG, el riesgo de que se realicen operaciones cr\u00edticas o cambios de configuraci\u00f3n se considera bajo. (Si los permisos del usuario PROG han sido cambiados por cualquier raz\u00f3n, existe un riesgo de que se realicen operaciones o cambios de configuraci\u00f3n bajo los permisos modificados. Los valores CVSS a continuaci\u00f3n son para los permisos predeterminados.)\n\nAdem\u00e1s, explotar esta vulnerabilidad requiere que un atacante ya tenga acceso a los controles de pantalla del HIS. Por lo tanto, un atacante ya puede operar y monitorear en ese punto, independientemente de esta vulnerabilidad.\n\nLas condiciones bajo las cuales se explota esta vulnerabilidad:\n\nSi se cumplen todas las siguientes condiciones, los productos afectados son vulnerables a esta vulnerabilidad.\n\n-Un atacante obtiene la contrase\u00f1a hardcodeada utilizando un m\u00e9todo determinado.\n\n-El HIS con el producto afectado instalado est\u00e1 configurado en modo de autenticaci\u00f3n CTM.\n\n-Un atacante debe tener acceso directo al HIS mencionado o ser capaz de irrumpir en \u00e9l de forma remota utilizando un m\u00e9todo determinado y realizar operaciones de pantalla.\n\nLos productos y versiones afectados son los siguientes: CENTUM VP R5.01.00 a R5.04.20, R6.01.00 a R6.12.00 y R7.01.00."
