Multiple buffer overflows in the ISSymbol ActiveX control in ISSymbol.ocx 61.6.0.0 and 301.1009.2904.0 in the ISSymbol virtual machine, as distributed in Advantech Studio 6.1 SP6 61.6.01.05, InduSoft Web Studio before 7.0+SP1, and InduSoft Thin Client 7.0, allow remote attackers to execute arbitrary code via a long (1) InternationalOrder, (2) InternationalSeparator, or (3) LogFileName property value; or (4) a long bstrFileName argument to the OpenScreen method.

Race condition in Advantech WebAccess before 8.1 allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via a crafted request.

WebAccess Versions 8.3.2 and prior. The application fails to properly validate the length of user-supplied data, causing a buffer overflow condition that allows for arbitrary remote code execution.

A local file inclusion (LFI) vulnerability exists in the options.php script functionality of Advantech R-SeeNet v 2.4.12 (20.10.2020). A specially crafted HTTP request can lead to arbitrary PHP code execution. An attacker can send a crafted HTTP request to trigger this vulnerability.

A privilege escalation vulnerability exists in the installation of Advantech WISE-PaaS/OTA Server 3.0.9. A specially-crafted file can be replaced in the system to escalate privileges to NT SYSTEM authority. An attacker can provide a malicious file to trigger this vulnerability.

Advantech WebAccess HMI Designer, Versions 2.1.9.31 and prior. Processing specially crafted project files lacking proper validation of user supplied data may cause a stack-based buffer overflow, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.
