Screen Creator Advance 2 Ver.0.1.1.4 Build01A and earlier is vulnerable to improper restriction of operations within the bounds of a memory buffer (CWE-119) due to improper check of its data size when processing a project file. If a user of Screen Creator Advance 2 opens a specially crafted project file, information may be disclosed and/or arbitrary code may be executed.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of KOYO Screen Creator 0.1.1.1. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SCA2 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-14868.

Use-after free vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier due to lack of error handling process even when an error was detected. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing control management information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing parts management information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing screen management information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing file structure information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

Out-of-bound read vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier because the end of data cannot be verified when processing template information. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

Out-of-bound write vulnerability exists in Screen Creator Advance 2 Ver.0.1.1.4 Build01 and earlier due to lack of error handling process when out of specification errors are detected. Having a user of Screen Creator Advance 2 to open a specially crafted project file may lead to information disclosure and/or arbitrary code execution.

Screen Creator Advance2, HMI GC-A2 series, and Real time remote monitoring and control tool Screen Creator Advance2 versions prior to Ver.0.1.1.3 Build01, HMI GC-A2 series(GC-A22W-CW, GC-A24W-C(W), GC-A26W-C(W), GC-A24, GC-A24-M, GC-A25, GC-A26, and GC-A26-J2), and Real time remote monitoring and control tool(Remote GC) allows a local attacker to bypass authentication due to the improper check for the Remote control setting's account names. This may allow attacker who can access the HMI from Real time remote monitoring and control tool may perform arbitrary operations on the HMI. As a result, the information stored in the HMI may be disclosed, deleted or altered, and/or the equipment may be illegally operated via the HMI.
