AdvantechCVEs & Vulnerabilities

Stack-based buffer overflow in Advantech WebAccess (formerly BroadWin WebAccess) 7.2 allows remote attackers to execute arbitrary code via the NodeName parameter.

The BrowseFolder method in the bwocxrun ActiveX control in Advantech WebAccess before 7.2 allows remote attackers to read arbitrary files via a crafted call.

The ChkCookie subroutine in an ActiveX control in broadweb/include/gChkCook.asp in Advantech WebAccess before 7.2 allows remote attackers to read arbitrary files via a crafted call.

upAdminPg.asp in Advantech WebAccess before 7.2 allows remote authenticated users to discover credentials by reading HTML source code.

Unspecified vulnerability in Advantech WebAccess before 7.2 allows remote authenticated users to create or delete arbitrary files via unknown vectors.

Multiple stack-based buffer overflows in Advantech WebAccess before 7.2 allow remote attackers to execute arbitrary code via a long string in the (1) ProjectName, (2) SetParameter, (3) NodeName, (4) CCDParameter, (5) SetColor, (6) AlarmImage, (7) GetParameter, (8) GetColor, (9) ServerResponse, (10) SetBaud, or (11) IPAddress parameter to an ActiveX control in (a) webvact.ocx, (b) dvs.ocx, or (c) webdact.ocx.

The BWOCXRUN.BwocxrunCtrl.1 control contains a method named “CreateProcess.” This method contains validation to ensure an attacker cannot run arbitrary command lines. After validation, the values supplied in the HTML are passed to the Windows CreateProcessA API. The validation can be bypassed allowing for running arbitrary command lines. The command line can specify running remote files (example: UNC command line). A function exists at offset 100019B0 of bwocxrun.ocx. Inside this function, there are 3 calls to strstr to check the contents of the user specified command line. If “\setup.exe,” “\bwvbprt.exe,” or “\bwvbprtl.exe” are contained in the command line (strstr returns nonzero value), the command line passes validation and is then passed to CreateProcessA.

The BWOCXRUN.BwocxrunCtrl.1 control contains a method named OpenUrlToBufferTimeout. This method takes a URL as a parameter and returns its contents to the caller in JavaScript. The URLs are accessed in the security context of the current browser session. The control does not perform any URL validation and allows file:// URLs that access the local disk. The method can be used to open a URL (including file URLs) and read the URLs through JavaScript. This method could also be used to reach any arbitrary URL to which the browser has access.

By providing an overly long string to the UserName parameter, an attacker may be able to overflow the static stack buffer. The attacker may then execute code on the target device remotely.

An attacker may pass an overly long value from the AccessCode2 argument to the control to overflow the static stack buffer. The attacker may then remotely execute arbitrary code.

An attacker may exploit this vulnerability by passing an overly long value from the AccessCode argument to the control. This will overflow the static stack buffer. The attacker may then execute code on the target device remotely.

An attacker can exploit this vulnerability by copying an overly long NodeName2 argument into a statically sized buffer on the stack to overflow the static stack buffer. An attacker may use this vulnerability to remotely execute arbitrary code.

To exploit this vulnerability, the attacker sends data from the GotoCmd argument to control. If the value of the argument is overly long, the static stack buffer can be overflowed. This will allow the attacker to execute arbitrary code remotely.

By providing an overly long string to the NodeName parameter, an attacker may be able to overflow the static stack buffer. The attacker may then execute code on the target device remotely.

An attacker using SQL injection may use arguments to construct queries without proper sanitization. The DBVisitor.dll is exposed through SOAP interfaces, and the exposed functions are vulnerable to SOAP injection. This may allow unexpected SQL action and access to records in the table of the software database or execution of arbitrary code.

Cross-site request forgery (CSRF) vulnerability in Advantech/BroadWin WebAccess 7.0 allows remote authenticated users to hijack the authentication of unspecified victims via unknown vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0235.

SQL injection vulnerability in Advantech/BroadWin WebAccess 7.0 allows remote authenticated users to execute arbitrary SQL commands via a malformed URL. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0234.

Multiple SQL injection vulnerabilities in Advantech/BroadWin WebAccess before 7.0 allow remote attackers to execute arbitrary SQL commands via crafted string input.

Format string vulnerability in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to execute arbitrary code via format string specifiers in a message string.

Advantech/BroadWin WebAccess before 7.0 allows remote attackers to cause a denial of service (memory corruption) via a modified stream identifier to a function.

GbScriptAddUp.asp in Advantech/BroadWin WebAccess before 7.0 does not properly perform authentication, which allows remote attackers to execute arbitrary code via unspecified vectors.

uaddUpAdmin.asp in Advantech/BroadWin WebAccess before 7.0 does not properly perform authentication, which allows remote attackers to modify an administrative password via a password-change request.

Stack-based buffer overflow in opcImg.asp in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to execute arbitrary code via unspecified vectors.

Advantech/BroadWin WebAccess 7.0 and earlier allows remote attackers to obtain sensitive information via a direct request to a URL. NOTE: the vendor reportedly "does not consider it to be a security risk."

Cross-site request forgery (CSRF) vulnerability in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to hijack the authentication of unspecified victims via unknown vectors.

Buffer overflow in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to execute arbitrary code via a long string value in unspecified parameters.

Cross-site scripting (XSS) vulnerability in bwview.asp in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters.

Cross-site scripting (XSS) vulnerability in bwerrdn.asp in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to inject arbitrary web script or HTML via unspecified parameters.

SQL injection vulnerability in Advantech/BroadWin WebAccess before 7.0 allows remote attackers to execute arbitrary SQL commands via crafted string input.

Buffer overflow in the Advantech ADAM OLE for Process Control (OPC) Server ActiveX control in ADAM OPC Server before 3.01.012, Modbus RTU OPC Server before 3.01.010, and Modbus TCP OPC Server before 3.01.010 allows remote attackers to execute arbitrary code via unspecified vectors.

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.

Stack-based buffer overflow in NTWebServer.exe in the test web service in InduSoft NTWebServer, as distributed in Advantech Studio 6.1 and InduSoft Web Studio 7.0, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a long request to TCP port 80.

The Advantech ADAM-6000 module has 00000000 as its default password, which makes it easier for remote attackers to obtain access through an HTTP session, and (1) monitor or (2) control the module's Modbus/TCP I/O activity.
