Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote host is running a version of Advantech WebAccess 7.2 prior to version 7.2-2014.07.30 It is, therefore, affected by multiple vulnerabilities :

- An overflow condition exists in the webvact.ocx ActiveX control due to improper validation of user-supplied input when handling the 'NodeName' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2014-0985)
- An overflow condition exists in the webvact.ocx ActiveX control due to improper validation of user-supplied input when handling the 'GotoCmd' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2014-0986)

- An overflow condition exists in the webvact.ocx ActiveX control due to improper validation of user-supplied input when handling the 'NodeName2' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2014-0987)

- An overflow condition exists in the webvact.ocx ActiveX control due to improper validation of user-supplied input when handling the 'AccessCode' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code.
(CVE-2014-0988)

- An overflow condition exists in the webvact.ocx ActiveX control due to improper validation of user-supplied input when handling the 'AccessCode2' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code.
(CVE-2014-0989)

- An overflow condition exists in the webvact.ocx ActiveX control due to improper validation of user-supplied input when handling the 'UserName' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2014-0990)

- An overflow condition exists in an unspecified ActiveX control due to improper validation of user-supplied input when handling the 'projectname' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code.
(CVE-2014-0991)

- An overflow condition exists in an unspecified ActiveX control due to improper validation of user-supplied input when handling the 'password' parameter. A remote, unauthenticated attacker can exploit this to cause a stack-based buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2014-0992)

Solution

Upgrade Advantech WebAccess to version 7.2-2014.07.30 or later.
