Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application’s control.

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow an authenticated user to use a specially crafted file to delete files outside the application’s control.

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Input is not properly sanitized and may allow an attacker to inject SQL commands.

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. An out-of-bounds vulnerability exists that may allow access to unauthorized data.

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. An improper validation vulnerability exists that could allow an attacker to inject specially crafted input into memory where it can be executed.

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple relative path traversal vulnerabilities exist that may allow a low privilege user to overwrite files outside the application’s control.

In Advantech WebAccess, Versions 8.4.2 and prior. A stack-based buffer overflow vulnerability caused by a lack of proper validation of the length of user-supplied data may allow remote code execution.

Advantech 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.

In WebAccess versions 8.4.1 and prior, multiple stack-based buffer overflow vulnerabilities are caused by a lack of proper validation of the length of user-supplied data. Exploitation of these vulnerabilities may allow remote code execution.
