Name of the Vulnerable Software and Affected Versions Kostac PLC Programming Software versions 1.6.9.0 and earlier

Description An out-of-bounds read issue exists due to insufficient buffer size for PLC program instructions, potentially leading to information disclosure and/or arbitrary code execution when opening a specially crafted project file.

Recommendations For versions 1.6.9.0 and earlier, consider avoiding the use of specially crafted project files until a patch is available. As a temporary workaround, restrict access to project files from untrusted sources to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
