Name of the Vulnerable Software and Affected Versions Tecnomatix RobotExpert versions prior to V16.1

Description The issue is related to the lack of proper validation of user-supplied data when parsing CELL files, which could result in an out of bounds write past the end of an allocated structure. This could allow an attacker to execute code in the context of the current process.

Recommendations For versions prior to V16.1, update to version V16.1 or later to resolve the issue. As a temporary workaround, consider restricting access to CELL files from untrusted sources to minimize the risk of exploitation.
