Name of the Vulnerable Software and Affected Versions Ansys SpaceClaim version 2022 R1

Description This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of JT files due to the lack of proper validation of user-supplied data, resulting in a read past the end of an allocated buffer. An attacker can leverage this to execute code in the context of the current process.

Recommendations For Ansys SpaceClaim version 2022 R1, consider disabling the JT file parsing functionality until a patch is available to prevent exploitation. Restrict access to malicious pages or files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
