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.Show less

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.Show less

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.Show less

The method can be used to open a URL (including file URLs) and read file URLs through JavaScript. This method could also be used to reach any arbitrary URL to which the browser has access.Show less

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.Show less

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.Show less

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.Show less

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.Show less

Absolute path traversal vulnerability in NTWebServer.exe in Indusoft Studio 7.0 and earlier and Advantech Studio 7.0 and earlier allows remote attackers to read arbitrary files via a full pathname in an argument to the sub_401A90 CreateFileW function.Show less

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.Show less

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.Show less
