Descriptions

There are multiple ways an unauthenticated attacker could perform SQL injection on WebAccess/NMS (versions prior to 3.0.2) to gain access to sensitive information.

Se presenta múltiples maneras en que un atacante no autenticado podría llevar a cabo una inyección SQL en WebAccess/NMS (versiones anteriores a 3.0.2) para conseguir acceso a información confidencial.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Advantech WebAccess/NMS. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the processing of calls to the addLinkMonitor method of the AddLinkMonitorAction class. When parsing the mail parameter of the addLinkMonitor.action endpoint, the process does not properly validate a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise.
