Descriptions

IBM Spectrum Protect Plus 10.1.0 through 10.1.5 could allow a remote attacker to traverse directories on the system. An attacker could send a specially-crafted URL request containing "dot dot" sequences (/../) to create arbitrary files on the system. IBM X-Force ID: 175019.

IBM Spectrum Protect Plus versiones10.1.0 hasta la versión 10.1.5, podría permitir a un atacante remoto saltar directorios del sistema.

This vulnerability allows remote attackers to create arbitrary files on affected installations of IBM Spectrum Protect Plus. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the Administrative Console Framework service. 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 create files in the context of an administrator.
