Se ha descubierto un problema de desreferencia de puntero no fiable en Advantech WebAccess en versiones anteriores a la V8.2_20170817. Un atacante remoto puede ejecutar código para desreferenciar un puntero en el programa, provocando que la aplicación deje de estar disponible.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the implementation of the 0x2775 IOCTL in the webvrpcs process. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this functionality to execute code under the context of Administrator.
