Descriptions

An unrestricted Upload of File with Dangerous Type vulnerability exists on numerous methods of the IIoT Monitor 3.1.38 software that could allow upload and execution of malicious files.

Existe una vulnerabilidad de subida sin restricción de archivos con tipos peligrosos en numerosos métodos del software de IIoT Monitor 3.1.38 que podría permitir la subida y ejecución de archivos maliciosos.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Schneider Electric IIoT Monitor. Authentication is required to exploit this vulnerability but authentication can be easily bypassed.
The specific flaw exists within the processing of the upload method of the UpgradeMgmt servlet, which listens on port 8080 by default. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
