VAR-201601-0038

Vulnerability from variot - Updated: 2025-12-22 23:49

Multiple stack-based buffer overflows in Advantech WebAccess before 8.1 allow remote attackers to execute arbitrary code via unspecified vectors. Authentication is not required to exploit this vulnerability.The specific flaw exists within the implementation of the 0x272F IOCTL in the ViewSrv subsystem. A stack-based buffer overflow vulnerability exists in a call to strcpy. An attacker can use this vulnerability to execute arbitrary code in the context of an administrator of the system. WebAccess HMI/SCADA software provides remote control and management, allowing users to easily view and configure automation equipment in facility management systems, power stations and building automation systems
