CVE-2019-10993: Advantech WebAccess Node viewsrv SQLPrepare Untrusted Pointer Dereference Remote Code Execution Vulnerability
In WebAccess/SCADA Versions 8.3.5 and prior, multiple untrusted pointer dereference vulnerabilities may allow a remote attacker to execute arbitrary code.
Other sources
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the 0x2776 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 vulnerability to execute code in the context of Administrator.
