TITLE

Advantech WebAccess Node webvrpcs drawsrv Untrusted Pointer Dereference Remote Code Execution Vulnerability

DESCRIPTION

In Advantech WebAccess versions V8.2_20170817 and prior, WebAccess versions V8.3.0 and prior, WebAccess Dashboard versions V.2.0.15 and prior, WebAccess Scada Node versions prior to 8.3.1, and WebAccess/NMS 2.0.3 and prior, several untrusted pointer dereference vulnerabilities have been identified, which may allow an attacker to execute arbitrary code. plural Advantech WebAccess The product includes NULL A vulnerability related to pointer dereference exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Advantech WebAccess Node. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x277e 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. Advantech WebAccess and others are products of Advantech. Advantech WebAccess is a browser-based HMI/SCADA software. The software supports dynamic graphical display and real-time data control, and provides the ability to remotely control and manage automation equipment. WebAccess Dashboard is one of the dashboard components; WebAccess Scada Node is one of the monitoring node components. WebAccess/NMS is a suite of web browsers for the Network Management System (NMS). Security vulnerabilities exist in several Advantech products. Multiple SQL-injection vulnerabilities 2. An information-disclosure vulnerability 3. A file-upload vulnerability 4. Multiple directory-traversal vulnerabilities 5. Multiple stack-based buffer-overflow vulnerabilities 6. A heap-based buffer-overflow vulnerability 7. Multiple arbitrary code-execution vulnerabilities 8. A denial-of-service vulnerability 9. A security-bypass vulnerability 10. A privilege-escalation vulnerability An attacker can exploit these issues to execute arbitrary code in the context of the application, or modify data, or exploit latent vulnerabilities in the underlying database, delete arbitrary files, gain elevated privileges, perform certain unauthorized actions, upload arbitrary files to the affected application gain unauthorized access and obtain sensitive information. Failed attacks will cause denial of service conditions. Advantech WebAccess, etc. Advantech WebAccess is a set of HMI/SCADA software based on browser architecture. The following versions are affected: Advantech WebAccess 8.2_20170817 and earlier, 8.3.0 and earlier; WebAccess Dashboard 2.0.15 and earlier; WebAccess Scada Node 8.3.1 and earlier; WebAccess/NMS 2.0.3 and earlier
