WADashboard API in Advantech WebAccess 8.3.1 and 8.3.2 allows remote authenticated attackers to write or overwrite any file on the filesystem due to a directory traversal vulnerability in the writeFile API. An attacker can use this vulnerability to remotely execute arbitrary code.

SQL injection vulnerability in Advantech WebAccess before 8.1 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.

An Uncontrolled Search Path Element issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. A maliciously crafted dll file placed earlier in the search path may allow an attacker to execute code within the context of the application.

Advantech WebAccess before 8.1 allows remote attackers to cause a denial of service (out-of-bounds memory access) via unspecified vectors.

Advantech WebAccess 8.1 and earlier contains a DLL hijacking vulnerability which may allow an attacker to run a malicious DLL file within the search path resulting in execution of arbitrary code.

WebAccess Versions 8.3.2 and prior. During installation, the application installer disables user access control and does not re-enable it after the installation is complete. This could allow an attacker to run elevated arbitrary code.

Advantech WebAccess 8.3.1 and earlier has an improper privilege management vulnerability, which may allow an attacker to access those files and perform actions at a system administrator level.

WebAccess Node (All versions prior to 9.0.1) has incorrect permissions set for resources used by specific services, which may allow code execution with system privileges.

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, an improper privilege management vulnerability may allow an authenticated user to modify files when read access should only be given to the user.

An Incorrect Privilege Assignment issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. A built-in user account has been granted a sensitive privilege that may allow a user to elevate to administrative privileges.

An Incorrect Permission Assignment for Critical Resource issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. Multiple files and folders with ACLs that affect other users are allowed to be modified by non-administrator accounts.

Advantech WebAccess Insufficient Type Distinction

Directory traversal vulnerability in Advantech WebAccess before 8.1 allows remote attackers to list arbitrary virtual-directory files via unspecified vectors.

An Untrusted Pointer Dereference issue was discovered in Advantech WebAccess versions prior to V8.2_20170817. A remote attacker is able to execute code to dereference a pointer within the program causing the application to become unavailable.

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, a path transversal vulnerability has been identified, which may allow an attacker to disclose sensitive information on the target.

Advantech WebAccess before 8.1 allows remote attackers to bypass an intended administrative requirement and obtain file or folder access via unspecified vectors.

Advantech WebAccess 8.3.4 allows unauthenticated, remote attackers to delete arbitrary files via IOCTL 10005 RPC.

In WebAccess/SCADA Versions 8.3.5 and prior, an out-of-bounds read vulnerability is caused by a lack of proper validation of user-supplied data. Exploitation of this vulnerability may allow disclosure of information.

Advantech WebAccess before 8.1 allows remote attackers to obtain sensitive information via crafted input.
