Descriptions

A vulnerability has been identified in SINEMA Server V14 (All versions). The affected application improperly sanitizes certain SNMP configuration data retrieved from monitored devices. An attacker with access to a monitored device could perform a stored cross-site scripting (XSS) attack that may lead to arbitrary code execution with `SYSTEM` privileges on the application server. (ZDI-CAN-19823)

Se ha identificado una vulnerabilidad en SINEMA Server V14 (todas las versiones). La aplicación afectada sanitiza incorrectamente ciertos datos de configuración SNMP recuperados de los dispositivos monitorizados. Un atacante con acceso a un dispositivo monitorizado podría realizar un ataque de Cross-Site Scripting (XSS) almacenado que puede llevar a la ejecución de código arbitrario con privilegios "SYSTEM" en el servidor de aplicaciones. (ZDI-CAN-19823)

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens SINEMA Server. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the processing of SNMP sysLocation OID. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of an arbitrary script. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
