VAR-201912-0756
Vulnerability from variot - Updated: 2023-12-18 13:43Advantech WebAccess before 8.4.3 allows unauthenticated remote attackers to execute arbitrary code or cause a denial of service (memory corruption) due to a stack-based buffer overflow when handling IOCTL 70533 RPC messages. Advantech WebAccess Contains an out-of-bounds vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Advantech WebAccess is a set of HMI / SCADA software based on browser architecture by Advantech of Taiwan, China. The software supports dynamic graphic display and real-time data control, and provides the ability to remotely control and manage automation equipment.
A buffer overflow vulnerability exists in Advantech WebAccess versions prior to 8.4.3. The vulnerability originates from a network system or product that incorrectly validates data boundaries when performing operations on memory, causing incorrect read and write operations to be performed on other associated memory locations. An attacker could use this vulnerability to cause a buffer overflow or heap overflow
